Application

Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc., and also used in food and drug packaging.

INSTRUCTION

Polypropylene, abbreviated as PP, is a colorless, odorless, non-toxic, translucent solid substance.

(1) Polypropylene 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 polypropylene 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, polypropylene materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical functions of metals. In addition, polypropylene has good grafting and compounding functions, and has huge application space in concrete, textile, packaging and agriculture, forestry and fishery.

PROPERTY

Polypropylene has many excellent properties:

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 110-120℃.

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 polypropylene products is better than that of high-density polyethylene products.
