Graphite/PTFE composite
Base resin: TECAPOWDER P84 HCM yellow, 325 mesh, filler 15 % graphite and 5 % PTFE
- Lower coefficient of friction compared to formulations without PTFE
- Outstanding friction properties on rough sliding surfaces through PTFE transfer to the opposite material
PTFE composite
Base resin: TECAPOWDER P84 HCM yellow, 325 mesh, blended with 30 % PTFE
- Lowest coefficient of friction of all PI composites
MoS2 composite
Base resin: TECAPOWDER P84 HCM yellow, 325 mesh, blended with 15 % MoS2
- For tribological applications in dry ambiance and vacuum
Carbon fiber
- Due to the negative thermal expansion of carbon fibers, the coefficient of linear thermal expansion of P84 can effectively be to the same level as metals. As well as the thermal transmission of such composites which is much better than under the use of graphite. Therefore, it is well known that blending only 0,5 % of carbon fibers (CF) in 3 mm length will double the heat transmission of plastics. The use of up to 30 % CF increases the flexural modulus significantly.
- A disadvantage is the poor machinability of such materials as well as the reduction of elongation. It is not possible to improve tensile strength of TECAPOWDER P84 using reinforcement fibers.
Glass fibers/balls
- The use of up to 50 % by weight of glass is used to improve the heat deflection temperature (HDT) of TECAPOWDER P84 in very temperature sensitive applications (for example welding apparatus or plasma guns; arc resistance required).
- The addition of 5 % PTFE to this composite improves machinability
