POTENTIOMETER HOUSING
Application: | Electronics Potentiometer Housing | |
Requirements: | Dimensional accuracy High temperature resistance Superior wear resistance against metal Low CLTE values Good ESD protection |
|
Recommendation: | PLASCO PDC 603LS PPS + 30% Carbon Fibers + 13% PTFE + 2% Si |
|
Solution: | The addition of 30% carbon fibers to PPS reduces shrinkage values
to +/- 0.0045. They also provide the ESD protection and good wear and friction values. The addition of PTFE further reduces the wear values especially against metals. The addition of a silicone lube provides the final improvement required to pass a 1 million cycles-to-failure test. PPS offers 500 degrees F heat resistance and CLTE values approach those of metal in the final composite. |
