1. Polyethylene: commonly used polyethylene can be divided into low pressure polyethylene (HDPE), high pressure polyethylene (LDPE) and linear high pressure polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact properties, film-forming properties, etc. LDPE and LLDPE are mainly used in packaging films, agricultural films, plastic modification, etc., while HDPE has a wide range of uses, such as films, pipes, and injection daily necessities.

 

2. Polypropylene: Relatively speaking, polypropylene has more varieties, more complex uses, and a wide range of fields. The varieties mainly include homopolymer polypropylene (homopp), block copolymer polypropylene (copp) and random copolymer polypropylene ( rapp), according to different uses, homopolymerization is mainly used in the fields of wire drawing, fiber, injection, BOPP film, etc., copolymer polypropylene is mainly used in household appliances injection parts, modified raw materials, daily injection products, pipes, etc., random polymerization Propylene is mainly used for transparent products, high-performance products, high-performance pipes, etc.

 

3. Polyvinyl chloride: Because of its low cost and self-flame retardant properties, it has a wide range of uses in the construction field, especially for sewer pipes, plastic steel doors and windows, plates, artificial leather, etc.

 

4. Polystyrene: As a transparent raw material, it has a wide range of uses when there is a need for transparency, such as automobile lampshades, daily transparent parts, transparent cups, cans, etc.

 

5. ABS: It is an engineering plastic with a wide range of uses. It has outstanding physical mechanical and thermal properties. It is widely used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as washing machines, air conditioners, refrigerators, etc. Electric fans, etc., are used in huge amounts, and they are also widely used in plastic modification.
