low friction surfaces for low temperature applications

It is also important that a high temperature plastic wear material have a relatively low coefficient of thermal expansion particularly if the polymer is to be used in direct contact with mating metal parts Plastics that are engineered for use in high temperature friction and wear applications include: Tecatron PVX TECAPEEK PVX One-part acetoxy cured silicone elastomer dispersed in Tert-Butyl Acetate Cures to a smooth silicone film that decreases the coefficient of friction (CoF) compared to the uncoated silicone and increases abrasion resistance for moving sliding and rubbing parts A non-blocking topcoat for silicone surfaces that is easy to clean and prevents the accumulation of Foreign Object Debris (FOD)

At very low sliding velocity the temperature increase is negligible because of heat diffusion but already for velocities of order 10(-2) m s(-1) the local heating may be very important Here I study the influence of the local heating on the rubber friction and I show that in a typical case the temperature increase results in a decrease in
