EPP materials have good sound insulation performance, and EPP products are highly effective in noise isolation.

But extremely hard development of polypropylene foam, belonging to high-tech, however, for foreign foamed polypropylene core technology also is in a few countries a few big companies, the main reason for polypropylene itself is determined by the unique physical properties.

Therefore, depend on the objective of the patented technology to produce foamed polypropylene has good market prospects of foam is formed in the gas dispersion in solid polymer micelles, foam plastic is qualitative light, adiabatic, buffer, insulation, anticorrosion, low price, etc.

Therefore, it is widely used in daily necessities, packaging, industry, agriculture, transportation, military industry and aerospace industry.

Demand of foamed plastics in recent years such as the United States market continued to grow at an annual rate of 4.2%. Our country since the 1990 s the development of the foam is very rapid, the main varieties have a polyurethane (pu) soft and hard foam plastic, polyethylene and polyethylene (PE) foam three categories.

However, all three kinds of materials have certain limitations.

Therefore, foamed polypropylene material arises at the moment.

Polypropylene resin has the characteristics of light weight, abundant raw material source, superior performance price, excellent heat resistance, chemical corrosion resistance and easy recovery.

It is the world's fastest growing general-purpose thermoplastic resin.

The research and development of polypropylene foam has become a hot topic in recent years.

At present, some developed countries are developing green packaging materials and instead expanded polystyrene, polypropylene foam particles and the foam sheet is the most typical one of the largest varieties and dosage.
