What materials can be used in injection molding?

A variety of materials can be used in injection molding, including thermoplastics, thermosets, and elastomers.

Thermoplastics: These are the most commonly used materials in injection molding, including polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-styrene (ABS), and polyvinyl chloride (PVC).

1. Thermosets: These materials are harder, more rigid, and more heat-resistant than thermoplastics. Examples include epoxy resins and phenolic resins.

2. Elastomers: These are rubber-like materials with high elasticity and flexibility. Examples include silicone, natural rubber, and styrene-butadiene rubber (SBR).

The choice of material depends on the specific application and requirements for the finished product. Properties such as strength, durability, flexibility, heat resistance, chemical resistance, and color can be tailored by using different materials and additives in the plastic pellets. In addition, recyclable and biodegradable materials are becoming increasingly popular in injection molding as part of a sustainable production process.
