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.

Technical Details & Test Data
- LNP™ Compounds Wear and Friction Solutions Bearings, Bushings, Cams and Sliders
At the push of a button, windows move, doors lock, copies get made, and HVAC comes to life. These electromotive actions require gears, bearings, bushings and other wear surfaces to provide smooth, reliable, actuation forces. LUBRICOMP™ and LUBRILOY™ compounds can help deliver the high quality performance required.
Thermoplastic Bearings
While resistance to wear is important for thermoplastic bushings/bearings, low friction can be more important. Heat generated from friction is often the limiting factor in plastic bearing applications. The operating load (P) and speed (V) of the application can be compared to the allowable, or “Limiting PV” of a candidate material. The data shown below was generated using a cylindrical half bearing test configuration, but modern thrust washer testers can be used to develop PV maps as well.
Internally Lubricated Compounds
The addition of an internal lubricant to a thermoplastic material can improve the wear resistance and reduce the coefficient of friction in plastic parts. Traditional lubricants like MoS2 , PTFE and PTFE/Si blends are common, with reinforcements like glass and carbon fiber adding strength and modulus. High temperature resins are sometimes required to resist deformation from friction generated heat.
