Main features:

      PP is a thermoplastic resin produced by polymerization of propylene. It has three configurations: isotactic, random, and syndiotactic. Industrial products mainly consist of isotactic compounds. Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually a semi transparent, colorless solid, odorless and non-toxic. Due to its regular structure and high degree of crystallization, it has a melting point of up to 167 C, is heat-resistant, and can be sterilized by steam. Its outstanding advantage is that its density is 0.90g/cm3, making it a lightweight general-purpose plastic. Corrosion resistant, with a tensile strength of 30MPa, and better strength, rigidity, and transparency than polyethylene. The disadvantage is poor low-temperature impact resistance and easy aging, but it can be overcome by modification and the addition of antioxidants separately. Features: non-toxic, tasteless, with low density, superior strength, stiffness, hardness, and heat resistance to low-pressure polyethylene. It can be used at around 100 degrees Celsius. It has good electrical properties and high-frequency insulation that are not affected by humidity, but becomes brittle, wear-resistant, and prone to aging at low temperatures. Suitable for making general mechanical parts, corrosion-resistant parts, and insulating parts. Common organic acids and bases; Rongqi has almost no effect on it and can be used as a tableware. Suitable for the storage of corrosive media and hazardous liquids in industries such as chemical engineering, refining, and pharmaceuticals.
