An Informational Brief on Polymer Machining Polychlorotrifluoroethylene (PCTFE) is a thermoplastic chlorofluoropolymer; some of its fluoropolymer cousins include: FEP, Kynar® PVDF, Teflon® PTFE and Halar® ECTFE. Fluoropolymers are known for their excellent chemical and hydro-resistance. This makes them candidates for critical applications, such as medical devices and industrial piping, where fluid exposure and hazardous materials can wear on a machined plastic part. AIP has over 37 years of... Read More
The last step in finishing a part is to apply an appropriate finish. Finishing a machined part can be as simple as smoothing off the burrs and other sharp edges or painting and coating the material to improve aesthetics and functionality. In the initial design phase of your project, talk to your machinist about the finishing processes to get a highly precise and extremely resilient piece. AIP has over... Read More
An Informational Brief on Polymer Machining Polyethylene terephthalate (PET or PET-P) is a general-purpose thermoplastic polymer which belongs to the polyester family. Highlights of this material include: an excellent combination of mechanical, thermal, chemical resistance and dimensional stability. Another notable characteristic of this material is that it is one of the most recycled thermoplastics. AIP has over 37 years of experience machining complex components from thermoplastics like Polyethylene... Read More
An Informational Brief on Polymer Machining ARDEL® Polyarylates are a family of aromatic polyesters. It has inherent UV stability and superior retention of optical and mechanical properties. These qualities combined make it an excellent choice for applications where weathering and wear are a concern. To make a comparison, polyaryls have similar mechanical properties to polycarbonates. Likewise, its impact strength can be compared to medium-impact ABS. AIP has over... Read More
What is Thermal Expansion (and Contraction)? Thermal expansion or contraction occurs when a material is exposed to temperature change and thus leads to change in all dimensions, as well as other physical properties. While this effect is most noticeable in gasses and liquids, it is also notable in solids. Softer materials such as unreinforced polymers experience greater levels of dimensional change per each degree change in temperature. When... Read More
