Product Description

Products Description

Polypropylen e is a polymer obtained by addition polymerization of propylen e. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89~0.91g/cm3, It is flammable, the melting point is 189°C, and it softens at about 155°C. The operating temperature range is -30~140°C. It is resistant to corrosion by acid, alkali, salt solution and various organic solvents below 80 °C, and can be decomposed under high temperature and oxidation.

 

INSTRUCTION Polypropylen e, abbreviated as PP, is a colorless, odorless, non-toxic, translucent solid substance. (1) Polypropylen e is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., which makes polypropylen e rapidly used in machinery, automobiles, electronic appliances, construction, textiles, packaging since its inception. It has been widely developed and applied in many fields such as agriculture, forestry, fishery and food industry. (2) Because of its plasticity, polypropylen e materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical functions of metals. In addition, polypropylen e has good grafting and compounding functions, and has huge application space in concrete, textile, packaging and agriculture, forestry and fishery.

1. The relative density is small, only 0.89-0.91, which is one of the lightest varieties in plastics.
2. Good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, good molding performance.

3. With high heat resistance, the continuous use temperature can reach 110-120ºC.
4. Good chemical properties, almost no water absorption, no reaction with most chemicals.
5. Pure texture, non-toxic.6. Good electrical insulation.
7. The transparency of polypropylen e products is better than that of high-density polyethylene products.
