Question

Accepted Answer

There are various types of plastic materials used in injection molding, including thermoplastics, thermosets, and elastomers.

Thermoplastics can be melted and re-melted, making them easy to mold and recycle. Examples include polyethylene, polypropylene, and polystyrene.
Thermosets cannot be melted and re-molded, making them more durable and heat-resistant. Examples include epoxy and phenolic resins.
Elastomers are rubber-like materials that can stretch and return to their original shape. Examples include silicone and polyurethane.
Other types of plastics used in injection molding include bioplastics, which are made from renewable resources, and engineering plastics, which have high strength and durability.
