What are the commonly used injection moulding materials?

2019-03-08 1077

Injection materials commonly used in injection moulding and plastic materials suitable for injection moulding, including PE PP PS and other plastics, have thermoplasticity and are suitable for hot injection moulding.

PE Material: PE, also known as polyethylene, is one of the most commonly used macromolecule materials in daily life. It is widely used in the manufacture of plastic bags, plastic films and milk drums.

PP material: Polypropylene, polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The absolute value of mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety in plastic materials, and its tensile strength can only reach 30 MPa or a little higher. Polypropylene with larger isotactic index has higher tensile strength, but with the increase of isotactic index, the impact strength of the material decreases, but it does not change when it drops to a certain value.

PS material: PS is polystyrene.

The above materials are commonly used in injection moulding.
