Polypropylene, referred to as PP, is a polymer of propylene through the addition polymerization reaction. It’s white waxy material, transparent and light in appearance. The chemical formula is (C3H6)n, the density is 0.89 ~ 0.91g/cm3, flammable, the melting point is 164~170 ° C, the softening is about 155 ° C, and the temperature range is -30 ~ 140 ° C. It can resist the corrosion of acid, alkali, salt solution and a variety of organic solvents below 80℃, and can decompose under high temperature and oxidation. Polypropylene is a thermoplastic synthetic resin with excellent properties. It is a colorless semi-transparent thermoplastic lightweight general plastic with chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear resistance. It is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipes, chemical containers, etc., and is also used in food and medicine packaging.

PP (polypropylene) is a widely used thermoplastic with a variety of excellent properties and a wide range of applications. The following are the properties and uses of PP:

Features:

1. Chemical stability: PP has good chemical stability and is not susceptible to acid, alkali, salt and other chemical substances.

2. Mechanical properties: PP has high tensile strength, bending strength and impact toughness, and can withstand greater mechanical stress.

3. Electrical performance: PP has good electrical insulation performance and can be used to manufacture wire insulation layer.

4. Thermal performance: The thermal stability of PP is good, and its performance can be maintained in a wide temperature range.

5. Processing performance: PP is easy to process and can be molded by injection molding, extrusion, blow molding and other processes.

6. Low density: The density of PP is low, which helps to reduce the weight of the product.

Application:

1. Automotive industry: PP is widely used in the automotive industry to manufacture bumpers, dashboards, seat frames and other components.

2. Packaging field: PP can be made into a variety of packaging containers, such as food packaging, beverage bottles, etc.

3. Wire and cable: PP can be used as the insulation layer and sheath layer of wire and cable, with good electrical insulation performance and chemical resistance.

4. Home appliance manufacturing: PP is also widely used in home appliance manufacturing, such as washing machines, refrigerators, etc.

5. Construction field: PP can be used to manufacture building templates, pipes, pipe fittings, etc.

6. Other fields: PP can also be used in medical equipment, sports equipment, office supplies and other fields.

In the cable industry, PP is widely used in the manufacture of wires and cables as an insulating layer and sheath layer. It has good electrical insulation properties, chemical corrosion resistance and processing properties, and can meet various performance requirements of cables. In addition, PP also has low density and good mechanical properties, making cable products more lightweight, easy to install and use. At the same time, the flame retardant and low smoke characteristics of PP also make it one of the ideal materials for fireproof cables, which can reduce the generation of smoke and the spread of fire in the event of fire. In general, PP has important application value in the cable industry, which can improve the safety performance and service life of cables.
