High Temperature Application Plastic bearings

  *PEEK Engineering plastics
     PEEK Polyether etherketone can be used at very high temperatures (+260℃) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength, PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260℃ and a very good resistance to all kinds of radiation. Lmportantl it is self-extinguishing according to UL 94.
