Anti-Corrosion plastic bearings

  *POM Engineering plastics elucidation

  *PEEK Engineering plastics elucidation

  *PP Engineering plastics elucidation
     PP(Polypropylene)shows a high mechanical strength, tensile strength, but a low notched impact strength, PP resists stress cracking and it is easy to weld. At minus temperatures it can get brittle. The chemical and electrical properties are very good. The temperature ranges between +5℃and +100℃.
