The structure of EPP foamed polypropylene material came into being. Polypropylene resin has the characteristics of light weight, rich material history, superior utility price ratio, excellent heat resistance, chemical corrosion resistance, easy to recover and so on. It is the world's fastest growing general purpose thermoplastic resin. Industry research and development of polypropylene foam has become a hot spot in recent years.
Now, EPP is developed countries are vigorously developing and as a substitute for foamed polystyrene green packaging materials, of which polypropylene foam particles and foam sheets are the most typical and the largest amount of varieties of polypropylene foam beads (EP) with PP as the primary material, the use of physical foam technology made of foamed beads. It is mainly used for sintering mold forming to a variety of shapes and standards for use in different occasions.
