- Wear and Friction Solutions Automotive Under-the-hood (UTH)
Current engineering demands in automotive power train applications emphasize reliability, efficiency, and light-weighting, but not with disregard of system cost. The application of thermoplastic solutions in gears, bearings, bushings and other moving parts is a recognized opportunity to provide high performance solutions that in the end save money.
High Temperature Demands
Applications like transmission seal rings, throttle body gears and other UTH actuators must operate at high temperatures, often under high loads and speeds, while exposed to automotive fluids. The expectation of reliability and safety put significant demands on the performance and life of these parts
Internally Lubricated Compounds
The addition of an internal lubricant to a thermoplastic material can help improve the wear resistance and reduce the coefficient of friction in plastic parts. Traditional lubricants like PTFE and PTFE/Si blends are common. The use of high temperature thermoplastic resins like PEEK, PPS and PPA can give performance at UTH temperatures.

- Note
- 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.
