- Mar 08, 2018 -

1. Polyethylene: Commonly used polyethylene can be divided into low density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). Among the three, HDPE has better thermal performance, electrical properties and mechanical properties, and LDPE and LLDPE have good flexibility, impact performance, film-forming and so on. LDPE and LLDPE are mainly used for packaging films, agricultural films, plastic modification, and HDPE for a wide range of uses, film, tubing, injection of daily necessities and other fields.

2. Polypropylene: Relatively, the variety of polypropylene is more, use is also more complex, a wide range of varieties are mainly poly polypropylene (Homopp), block copolymer polypropylene (COPP) and random polypropylene (Rapp), according to the use of different, are mainly used in wire drawing, fiber, injection, BOPP film and other fields, Copolymer polypropylene is mainly used for injection parts of household appliances, modified raw materials, daily injection products, pipe, etc., the random polypropylene is mainly used for transparent products, high-performance products, high-performance pipe and so on.
