Application prospect and forming process of epp material

Epp material superior performance, has a variety of reliable performance, far more than ordinary foam plastics, widely used in various industries such as packaging, transportation, automobile, and so on, today we will understand the scope of application and molding process of foamed polypropylene material

I. application prospect of epp materials

Foamed polypropylene (EPP), foamed polystyrene, foamed polyurethane, foamed polyethylene terephthalate, etc., is a resin-matrix material filled with bubbles, which can also be regarded as gas-filled resin matrix composites.

EPP is widely used in automobile interior decoration, exterior decoration, hood and other parts, which helps to reduce vehicle weight, and play a role in noise reduction, shock absorption and heat preservation.

With the rapid development of global automotive lightweight, new energy vehicles and high-speed railway, the demand for EPP is increasing. Developed countries such as Japan, the United States and Europe are competing to develop high-performance products.As a new chemical material, EPP will be an important field of polypropylene development.

How is epp material formed

EPP molding process, there are mainly four: batch foaming method (also known as caldron pressure foaming method), mold pressure foaming method, extrusion foaming method and injection micro-foaming method.

The industrial production of EPP and EPET extrusion foams has been realized in foreign countries. At present, caldron pressure method and mold pressure method are mainly used in China, and few research achievements on extrusion foams are obtained.

At present, the production process of epp material is still being improved. With the progress of technology, epp material will have better and better performance and lower and lower cost, which will replace other foam plastics and become the mainstream in the market.Welcome to consult canary (suzhou) environmental material co., LTD.
