Specialized industries necessitate specialized materials.  Heavy industrial equipment requires materials with strength and resilience to handle high-loads.  Chemical processing applications, such as galvanic tanks or liquid storage tanks need high chemical and corrosion resistant materials.  On an amusement park ride, materials must be high-impact, weight-bearing and durable, as well as aesthetically pleasing.  Although these are all various applications, AIP can precision machine composites to provide solutions for any project’s exact specifications.


In this issue of AIP’s latest blog, we discuss the diverse thermoplastics we machine for the specialized industrial sector.


Read on to find out about the benefits of the following thermoplastics:


  • PEEK
  • Polysulfone
  • Radel
  • PPS
  • Delrin




product made of peek materialPEEK (polyetheretherketone) is a lightweight thermoplastic known for excellent chemical and moisture resistance.  For this reason, it has versatile applications in multiple industries:  Medical & Life Sciences, Power & Energy, Aerospace & Defense and the Specialized Industrial Sector.


PEEK is a semi-crystalline, high-performance thermoplastic. This means it has enough elasticity to be machined to various custom designs, with strong mechanical properties that provide resistance to fatigue and stress-cracking, as well as a good structure for bearing, wear and structural applications.


In the Specialized Industrial Sector, PEEK is a great option for food and beverage filling or automated manufacturing equipment because it is highly chemical and moisture resistant.


Applications Include:

  • Metal Replacement
  • Processing Equipment
  • Vacuum Chamber Applications
  • Semiconductor Manufacturing Equipment


Polysulfone – PSU


product made of peek materialMade from UDEL Resin, PSU (Polysulfone) is a high-performance thermoplastic that retains its properties in temperatures ranging from -150°F (-100°C) to 300°F (150°C).


Further properties include:

  • Excellent Radiation Stability
  • Chemical resistance
  • Hydrolysis Resistance For Constant Use In Hot Water And Steam


Applications Include:

  • Stainless Steel Replacement
  • Aluminum Parts Replacement
  • Semiconductor Process Equipment Components


Radel – PPSU


product made of peek materialWith high heat and high impact performance, RADEL delivers better impact resistance and chemical resistance than other sulfone-based polymers, such as UDEL and ULTEM. Its toughness and long-term hydrolytic stability mean it performs well even under autoclave pressure. Notably, RADEL can also be polished to a mirror finish and is FDA and NSF approved for food and beverage contact.


Applications Include:

  • Electronic Burn-in Sockets
  • Precision Filter Components
  • Steam Autoclave Cycle


Ryton – PPS


product made of peek materialDid you know that PPS (or Polyphenylene sulfide) products offer the broadest resistance to chemicals of any advanced engineering plastic? Other properties include high temperature stability, hydrolysis resistance, superb dimensional stability and structural durability. It’s no surprise that this makes it a popular choice for industrial usages.


Applications Include:

  • Chemical Pumps
  • HPLC Components
  • Semiconductor Wafer CMP Clamp Rings
  • Theme-Park Coaster Wheel Bushings




product made of peek materialThis polymer is an amorphous, amber-to-transparent thermoplastic.  ULTEM is often sought after for its high ductility, thermal resistance, rigidity and comprehensive chemical endurance.  AIP machines ULTEM into many components, especially electrical insulation parts in the specialized industrial sector.

Applications Include:

  • Analytical Instrumentation
  • Dielectric Properties Required
  • Electrical Insulators
  • High Strength Situations
  • Semiconductor Process Components
  • Structural Components
  • Underwater Connector Bodies




product made of peek materialTORLON, PAI (polyamide-imide), is an amorphous, high-performance thermoplastic. Due to its consistent performance at severe levels of temperature and stress, TORLON is ideal for critical mechanical and structural components of jet engines, automotive transmissions, oil recovery, off-road vehicles and heavy-duty equipment.  Explore the TORLON Machining Guide from AIP for information on applications and capabilities of this incredible polymer.


Applications Include:

  • Bearing Cages
  • High Temperature Electrical Connectors
  • Structural Parts
  • Valve Seats
  • Wear Rings


Delrin – Acetal (Polyoxymethylene)


product made of peek materialThis semi-crystalline material provides unprecedented strength and stiffness while maintaining a low coefficient of friction and good wear properties in wet environments. Excellent for high moisture or submerged applications, Acetal significantly outperforms Nylon in these environments.


Several different grades of Acetals are available that AIP machines: PTFE-filled Acetals with lower coefficients of friction (ideal where impact strength and wear capability are needed), glass-reinforced Acetals with a much higher strength and greater heat resistance and FDA-compliant Acetals for medical- and food-related applications.


Applications Include:

  • Electrical Insulators
  • Industrial Bearings
  • Rollers
  • Gears
  • Scraper Blades
