GEHR Plastics PP-30PET-F Polypropylene, 30% PET Fiber Reinforced  (discontinued **)
Categories: Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polypropylene (PP)

Material Notes: Polypropylene shows a high mechanical strength and a 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 continuous operating temperatures ranges between 5°C and 100°C.

Properties

  • low weight
  • high heat resistance
  • high tensile strength
  • high surface strength
  • high chemical resistance
  • low oxidation resistance
  • low abrasion resistance
  • brittle in the coldness
  • HF-welding not possible
  • natural color is not weather resistant
  • strong relationship between mechanical and impact strength
  • fractrue behavior is splinter-proof for passive safety
  • good acoustic characteristics
Applications
  • pumps
  • valves
  • gaskets
  • supporting stands
  • spacer for the plating
  • particles for toys
PP-30PET-F is 30% PET fiber reinforced and has optimized stiffness with an improved notched impact strength at the same time.
