PP is a thermoplastic raw material with good heat resistance, corrosion resistance, mechanical strength and rigidity, as well as good fatigue and impact resistance. The density of PP is relatively small, with a specific gravity of only 0.90-0.91g/cm ³， Therefore, it has a lighter weight and better plasticity. PP also has good electrical insulation performance and transparency, as well as good weather resistance and durability. Widely used in various fields, such as household goods, food packaging, medical devices, automotive components, electronic equipment, building materials, etc.
