It is a white waxy solid, and its low density, strength, stiffness and hardness are high, the gloss is good. Having good heat resistance, high insulation properties. The melting temperature has good fluidity, good formability.
Polypropylene is a crystalline plastic, color wood-like material is a white, transparent than PE, according to its different degree of crystallinity, forming a transparent to translucent products. Light weight, specific gravity than water, polyethylene surface is hard, thin-walled products resistant to folding.
Density, strength stiffness, hardness and heat resistance are superior to low pressure polyethylene, can be about 100 degrees.
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. PP Due to high crystallinity, surface of the material stiffness and good resistance to scratches; Environmental stress cracking problem does not exist.
It's 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.
