Pp tarpaulins, as the name implies, is made of pp material that tent.
Is made up of propylene polymerization and obtained a thermoplastic resin.
And gauge, gauge between random and three types of configurations, industrial products and rules as the main component.
Polypropylene also includes copolymer of propylene and a small amount of ethylene.
Usually a transparent colorless solid, odorless drug-free.
Because of its neat and high crystallization structure, therefore, melting point 167 ℃, heat resistant, products available steam sterilization is its outstanding advantages.
Density of 0.
90 g/cm3, which is the lightest general plastics.
Corrosion resistance, tensile strength 30 mpa, intensity, rigidity and transparency are better than polyethylene.
Drawback is the low temperature impact resistance is poor, easy ageing, but can be respectively through modification and adding antioxidants to be overcome.
So the corresponding tarpaulins, also has the polypropylene (
