All Types And Characteristics Of Rotational Molding Raw Materials

Main types

Polyethylene (PE)

The most commonly used rotational molding raw materials: Polyethylene accounts for the vast majority of the rotational molding raw material market, especially linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE).

Features: Good processing performance, heat resistance, weather resistance and high strength. LLDPE has better flexibility and impact resistance, while HDPE has higher rigidity and hardness.

Polypropylene (PP)

Features: Polypropylene has excellent chemical resistance, heat resistance and high mechanical strength. However, its application in the rotational molding process is relatively rare because its processing performance may be slightly inferior compared to PE.

Other polymers

Including polycarbonate, nylon, ABS resin and other synthetic resins. These materials have unique advantages in certain specific applications, such as the high transparency of polycarbonate, the wear resistance of nylon, and the easy processing of ABS resin.
