Materials Used in Rotomolding

The most common material used in roto molding is Polyethylene (PE), accounting for 97% of rotomolded products. This material is versatile, available, and easy to mold. It can be easily ground to powder, which is suitable for this technique (which usually requires powder over granules).

Other options for rotomolding include:

Polypropylene (PP): Although this material has poor impact strength at cold temperatures, it has great resistance to cracking from chemical and environmental stress, superior stiffness, and a higher thermal distortion temperature.
Nylons (PA): Because of their excellent technical performance, nylon materials are perfect for rotational molding applications. Though some nylon types (Nylon 6) require an inert atmosphere (usually nitrogen), making the roto molding process a bit complicated, its low cost can make up for the challenge.
Polycarbonate (PC): It’s a translucent, high-strength polymer with built-in flame retardancy. Polycarbonate may need extensive technological processing due to its poor impact resistance.
Plasticized polyvinyl chloride (PVC): It’s a liquid substance that resists certain chemicals and has good weathering and aging qualities. Each grade has different flexibility, impact, and temperature performance.
