Commonly used plastic varieties performance
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, 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 applications, such as films, pipes, and injection daily necessities.
2. 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, and artificial leather.
3. 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.
