PEEK’s Dominance in Medical Device Manufacturing

In the competitive landscape of medical device manufacturing, the choice of material plays a pivotal role in determining the quality, reliability, and safety of the end product. PEEK (polyetheretherketone) has emerged as an exceptionally promising alternative to traditional metals, presenting a slew of benefits that cater specifically to the unique demands of the medical field.

In particular, PEEK’s unique qualities make it a prime choice for medical applications where chemical resistance and exposure are prominent. Whether inside the body or in the operating room, PEEK provides biocompatibility, structural stability, and continuous mechanical functionality at high temperatures in critical environments.

Join us in our informational brief on why medical device manufacturers are increasingly seeking PEEK over metals for medical R&D applications.



Biocompatibility and Safety

PEEK excels in biocompatibility, a critical factor for medical devices, especially those that come into direct contact with the body. It has successfully cleared all ISO 10993 biocompatibility tests for both short and long-term implants. This ensures minimal risk of adverse reactions when used in vivo, eliminating concerns associated with metals, such as metallosis or allergic reactions.

In a case study for reducing the need for brain surgery operations, PEEK became the top choice material for Dynamic Telescopic Craniotomy. Not only did this PEEK innovation provide biocompatibility with human tissue, it also expanded with brain swelling following a cranial surgery. This vital aspect of PEEK’s performance as a polymer highlights how it can advance brain surgery techniques and improve recovery times for patients.



Adaptable Design and Customization

PEEK’s inherent versatility supports a broad range of intricate and patient-specific designs. It can be CNC machined to create detailed medical devices or components with high precision. This adaptability is especially beneficial in the dynamic landscape of medical technology, where ongoing innovation and customization are paramount.

PEEK’s ability to perform with human tissue and fluids makes it an excellent choice for spinal implants, brain flap surgeries, and facio-skeletal restructuring.

Chemical Resistance and Sterilization Ease

In the medical world, devices often come into contact with a variety of chemicals, be it medications, sterilization agents, or bodily fluids. PEEK is chemically inert, resisting potential degradation or reactions that could compromise the device’s functionality or patient safety. Furthermore, PEEK devices can be sterilized using standard medical sterilization techniques without compromising the material’s integrity.


Advantages of PEEK’s chemical resistance

PEEK is relatively inert and biocompatible while also withstanding temperatures up to 100°C. Under the right circumstances, .005” – .020” ID tubing can be used up to 5000 psi for a limited time, and 0.030” to 3000 psi. Larger IDs are typically good to 500 psi. These limits are substantially reduced at elevated temperatures and in contact with some solvents or acids. Its mechanical properties allow PEEK to be used instead of stainless in many situations and in some environments where stainless would be too reactive.

However, PEEK can be somewhat absorptive of solvents and analytes, notably methylene chloride, DMSO, THF, and high concentrations of sulfuric and nitric acid. This tubing is highly prone to “kinking”, or sealing off, if held in a sharp bend over time.

The chart at the right shows the chemical resistance of PEEK at 200°C (420°F). PEEK exhibits excellent resistance to a wide range of organic and inorganic chemicals. The compatibility of PEEK with many chemicals at 20 °C (68 °F) has been investigated and the results for unreinforced grades are favorable. PEEK is compatible with almost any of the solvents used in HPLC. The only solvent which will attack PEEK are concentrated nitric acid and sulfuric acids.




PEEK Performance and Innovation

The demands of the medical device industry are uniquely stringent, requiring materials that are safe, reliable, and adaptable. PEEK, with its remarkable blend of properties tailored to medical needs, has proven to be an invaluable choice for manufacturers. By integrating PEEK into their production, medical device manufacturers can ensure not only the longevity and reliability of their products but also the safety and well-being of the patients they serve.

Traditional metals such as titanium have a strong challenger in PEEK’s performance and innovation offering. It provides a combination of biocompatibility, chemical resistance and machinability that the medical industry demands.

While PEEK is a more expensive material, the benefits in long-term patient care and medical advancements can make a difference in ROI.

A Brief History of PEEK in Orthopedic Surgery


Since the 1980s, Polyaryletherketones (PEEK) have been utilized as biomaterials in trauma, orthopedic, and spinal implants. Due to its relative inertness, radiolucency and chemical resistance, PEEK has had the greatest clinical impact in spine implant design.


Laboratory studies during the 1990s confirmed that PEEK implants had the needed combination of wear, strength, creep, and fatigue resistance to replace the metallic biomaterials in spinal implants. An intervertebral fusion cage was the first piece of spinal instrumentation that had been made with PEEK rather than metal. It was implanted in 1999 and made with PEEK-OPTIMA™ from Invibio Biomaterial Solutions.


The Future of PEEK Beyond Spinal Implants


Since then, PEEK has only expanded as a performance biomaterial for instrumented spine surgery. In the United States, spine fusion is one of the leading surgeries for patients who suffer from chronic neck and back pain that does not respond to preliminary treatments.


According to Orthopedic Design & Technology, around 215,000 Americans underwent spine fusion procedures in 1997. By 2007 that number had increased to 402,000. PEEK is now an established biomaterial that will only continue to expand.


The Biocompatibility and Biostability of PEEK

PEEK displays excellent biocompatibility and biostability as a performance medical-grade material. To differentiate, let’s briefly discuss biocompatibility versus biostability.


Biocompatibility – The biological requirements of a biomaterial or biomaterials used in a medical device. When it comes into contact with human tissue and fluids, it’s compatible with the environment and will not incur adverse effects.


Biostability – The ability of a material to maintain its physical and chemical integrity after implantation into living tissue. The FDA mandates that any medical material that comes into direct or indirect contact with human tissue and fluids must maintain mechanical and molecular integrity.


Anything touching or interacting with human tissue and bone must be both biocompatible and biostable for a patient. This is one area where metals fail compared to PEEK. Metals like titanium are a standard material for spinal fusion, yet clinical studies continue to reveal the advantages of PEEK.


Benefits of PEEK for Spinal Fusion

PEEK has a growing advocacy in the field of orthopedics for cervical fusion as well as spinal fusion. Published literature supports the material’s advantages and highlights these key benefits for patients with spinal and cervical fusion surgery:

  • • Improved spinal alignment and geometry
  • • Reduced hospital stays and decreased blood loss
  • • Decreased complication rates
  • • Good/excellent functional outcomes and improved patient satisfaction
  • • Excellent fusion rates


Biomaterial Comparison: PEEK Versus Metals

When it comes to standards of medical biomaterials, PEEK tends to outshine metals such as stainless steel and even titanium alloy.


Stainless Steel

Stainless steel has the advantage of being inexpensive, durable, and easily alloyed. However, as medical practices have advanced, stainless steel is often replaced by titanium and PEEK implants for spinal fusions.


First, stainless steel has low biocompatibility and is more likely to leech artifacts due to corrosion once implanted. This is a danger to patient safety and increases the need for surgeries overtime. PEEK, on the other hand, closely resembles cortical bone tissue and is flexible enough to graft onto tissue.


Additionally, metals like stainless steel visually obscure the healing site under fluoroscopy, making it more difficult for doctors to see whether the spine is healing correctly when doing checkups via X-rays or MRIs. Conversely, PEEK is a radiolucent material that offers ease, comfort, and a clear view to monitor stability and healing.


Titanium Alloy

Titanium alloy is an accepted standard biomaterial for spinal and cervical fusion surgeries. Compared to PEEK, it has a similar rate of fusion for cervical and lumbar spine fusions.


One potential complication of spinal fusion is the subsidence of disc height in the post-operative period. Recent studies to assess subsidence in titanium and PEEK cages showed a notably increased rate of subsidence in titanium versus PEEK in patient follow-ups.


This is a serious concern for surgeons looking to improve the rate of patient recovery and lessen repeat spinal fusion surgery. In this regard, PEEK is a superior performance material for safer and better spinal fusion practices.


Advancing Orthopedic Innovation With Medical-grade PEEK


The fields of orthopedics and spinal fusion continue to research new methods for best practices in the industry. Over the last three decades, medical-grade PEEK has established itself as the performance biomaterial of choice for surgeons and OEMs. Medical device design demands the highest level of sanitation, biocompatibility, and precision in one of the most extreme environments, the human body.


As a material that closely resembles cortical bone, PEEK has an established advantage over other metals such as titanium that have shown degradation and leeching over time. As OEMs search to expand the horizon of orthopedic medicine, PEEK polymer machinists like AIP stand at the ready to provide unrivaled expertise on design, function, and quick prototyping.

Torlon® Takes the Heat in Mission-Critical Aerospace Components


Few businesses on the planet share the same level of scrutiny towards their components as those in the aerospace industry. The material properties of Torlon® are what make the high-performance thermoplastic a top material pick in the industry.


To pass the benchmark, aerospace components must be:

  • – Impervious to corrosive and oxidizing chemicals
  • – Able to function in both cold and hot environments
  • – Lightweight to reduce overall vehicle weight and increase payload
  • – Strong enough to withstand constant friction, impact, wear, temperature extremes, and high pressures


Few polymer materials can check all those boxes, but Torlon® is among them. For decades aerospace OEMs have relied on Torlon® to solve unique challenges in the aerospace and defense sector. One of its most outstanding properties is the ability to maintain mechanical stability at extreme temperatures. For this reason, it’s often used for bushings, fasteners, and screws in Boeing 787s and even F-16 fuel and air connectors.


Properties of Torlon®

Besides incredible thermal stability and resistance rivaling aluminum, copper, and steel, Torlon®  is well known for its strength under pressure and chemical resistance. Torlon’s benefits include the following:


  • – Wear resistance in dry and lubricated environments
  • – Maintains strength and stiffness up to 500°F (260°C)
  • – Low-temperature toughness and impact strength
  • – Chemical resistance, including acids and most organics
  • – Low creep and wear under load
  • – Excellent compressive strength and extremely low CLTE
  • – Low flammability and smoke generation

High-Temperature Wear Resistance

Torlon® falls within the family of imidized performance polymers. Celazole® (PBI), VESPEL® (PI), and Torlon® (PAI) all perform at elevated temperatures up to and above 500°F (260°C). These grades of thermoplastics have resistance to chemicals, steam, and wear. Torlon® PAI is often accepted as a metal replacement in aerospace applications where temperatures range from cryogenic to extreme heat, and the application requires thermal/electrical insulation and weight reduction.



Torlon® Solves Tough Aerospace Challenges


Torlon® has been a critical material for many years with industries relying on its innate qualities to solve complicated challenges. How can Torlon® do the same for the aerospace industry? Consider the following:


1. Boeing thermal isolators – Increasing fuel efficiency by reducing aircraft weight is a constant goal for the aviation industry. In the case of the Boeing 787, Torlon® was able to help make that goal attainable. The engineers at Boeing theorized they could reduce the overall weight of the aircraft by feeding hydraulic lines through the fuel tanks rather than around them. For this to work, the hydraulic lines needed insulation that could handle being exposed and heated by harsh environments. Torlon® 4203 PAI was a perfect choice because it does not conduct heat nor electricity, which would have caused problems, as temperatures range from -40°F (-40°C) up 350 F (177°C).


2. Boeing bushings for blocker doors – Blocker doors allow the aircraft to slow down by creating a reverse thrust. The doors must be precise, and that task falls to the bushings in the hinge assembly. They must maintain a low friction and wear rate while surviving temperatures ranging from -40° to 500°F (260°C), and all without lubrication. Torlon® 4301 PAI provides all these needed properties.


3. Worldwide Aviation fastening screws – Aerospace OEMs need screws made from a material that can provide a capacity for heavy load-bearing while being optimized for production. In the case of radar systems, the screws also need to be made out of a material that won’t interfere with detection capabilities. For that reason alone, metal screws are out, as they’ll interfere with the radar’s ability to function. Torlon® 4203, on the other hand, is both RFI and EMI transparent, it doesn’t corrode, and it has a fantastic strength-to-weight ratio.


4. F-16 fuel and air connectors – With auxiliary tanks, the F-16 can take on the role of a strategic bomber, as its range is extended by a full 50%. At first, the fuel connectors were made from stainless steel but required additional insulation against lightning strikes, rendering metal connectors infeasible. Finding an alternative material proved difficult due to other variables; it needed to be resistant to temperatures up to 400°F (205°C), be chemically resistant to jet fuel, and handle constant vibrations. Torlon® 4203 was the answer, as it reached all those requirements while also handling pressures beyond 650 psi. This choice improved both the part performance and manufacturing costs.


In all of these real-world examples, Torlon® demonstrates its superiority in strength and thermal stability. The fact that it’s successfully used in critical applications is proof of the material’s reliability.
