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.
·very high mechanical strength
·very high rigidity
·very high thermal stability
·very high dimensional stability
·very high radiation resistance
·very high hydrolysis resistance
|| Disadvantages ：
·notched impact strength relatively low
low resistance to acetone
