High temperature resistant precision structural parts PIN ejector series

        

Features

        
  • Heat resistance: Continuous use of heat resistant temperature up to 288 ° C, short time use up to 480 ° C. Abrasion resistance: Vespel's non-lubrication limit PV value is more than 10 times that of general engineering plastics, hedging Both wear and vibration wear have strong tolerance.
    Creep: Creep at 260 ° C and 186 KG/cm 2 , only 1000 hours 0.6%. Deformation of load: Teflon at 50 ° C and 140 KG/cm 2 1/70, 1/10 of nylon.
