Types of Rotationally Molded Plastics and Rotational Molding

Sep 22, 2017

Cross-linked polyethylene is an ideal material for rotomolded products that will be exposed to extremely cold temperatures. 

Custom rotational molding services allow customers to design rotomolded products to their specifications.

High-density polyethylene (HDPE) offers high-flow molding and high molecular weight performance in rotationally molded parts. Properly rotomolded HDPE products will have interior gloss development, ductile cold temperature impact performance and an off-gas odor that confirms the chemical cross-linking reaction. 

Linear low density polyethylene (LLDPE) provides superior fit and finish to rotationally molded products. Rotomolded LLDPE products also have high impact, tensile and dielectric strength. 

Plastic rotational molding is the process of rotating molten plastic material in a mold in order to shape it into a useful product.

Polyethylene (PE) is a lightweight plastic that has a low modulus of elasticity. Rotationally molded PE products are thick in desired places and have good impact resistance. 

Polyvinyl chloride (PVC), also referred to as "vinyl," has excellent transparency, chemical resistance, long-term stability, good weatherability, flow characteristics and stable electrical properties. PVC can be either rigid or flexible. 

Rotational molders, also known as rotational moulders or roto moulders, are used to fabricate hollow plastic parts.

Rotational moulding is the low pressure process used to create hollow plastic components.

Rotationally molded fuel tanks are seamless polyethylene (PE) tank structures that retain molded-in logos, warnings, serial numbers and other full color graphics when exposed to salt water, sunlight, solvents, cold weather and other severe conditions.

Rotationally molded plastics are one-piece products created on a rotational molding machine.

Rotomolds are machines used to make hollow, one-piece plastic parts.

Rotomolded products are hollow plastic parts formed by rotational plastic molding processes.

Rotomolded tanks are hollow plastic containers used for the storage of materials, often in bulk quantities.

Rotomolding, also known as rotomoulding, is the four-step process used to make hollow plastic components.
