Design engineer look to replace metal parts and components with thermoplastics whenever possible. Not only can they be produced more cost-effectively, they offer greater design flexibility, weigh less and resist corrosion. The availability of high temperature resins like PEEK, PPS, PPA and PEI can stretch the use of thermoplastic even further.
If you can’t stand the heat… internally lubricated compounds: While auto under-the-hood and industrial machinery might be the first to come to mind, high temperature application are not always driven by hot operating environment. Some application that may never see elevated use temperatures have to survive a hot manufacturing environment (lead-free solder, paint ovens). High temperature generally feature good chemical resistance as well.
Internally lubricated compounds:
The addition of an internal lubricant to a thermoplastic material can improve the wear resistance and can reduce the coefficient of friction in plastic parts. Traditional lubricants like PTFE and PTFE/Si blends are common. Compounds made with high temperature resins can provide wear performance comparable with externally lubricated metal parts.

- ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
- ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
