Polypropylene(PP) PP description: PP polypropylene pellets of color, cylindrical particles that smooth, odorless, non-toxic, no mechanical impurities. Has good electrical properties and high-frequency insulation from humidity, but the low temperature brittle not wear, easy to aging, PP copolymer-based material has a lower heat distortion temperature, low transparency, low gloss, low rigidity, but have a stronger impact strength. The strength of PP increases with increasing ethylene content. PP Due to high crystallinity, surface of the material stiffness and good resistance to scratches; Environmental stress cracking problem does not exist. PP application: Suitable for production of general machinery parts, corrosion-resistant parts and insulating parts. For the production of daily necessities, such as cups, buckets, pots; Industrial supplies generally require relatively high performance, such as auto parts, sports equipment and so on.
