1. EPP has multiple meanings. Enhance parallel port, polypropylene plastic foam material, expand supply protocol, terminal potential, PHP project development compiler, etc.

EPP， Polypropylene plastic foam material is a highly crystalline polymer material with excellent performance, and is an environmentally friendly, pressure resistant, buffering, and heat-insulating material. EPP products have excellent seismic and energy absorption performance, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance, and thermal insulation. In addition, their lightweight can significantly reduce the weight of items.

The application fields of EPP are becoming increasingly widespread. EPP has been widely used as packaging material for IT products, electronic communication equipment, LCD displays, plasma TVs, precision electronic components, and precision instruments and meters. Another particularly important application area is the extensive use in the automotive industry: car bumpers, car side shock absorbers, car door shock absorbers, advanced safety car seats, child safety seats, toolboxes, trunk, armrests, floor mats, sun visors, instrument panels, etc. (according to statistical data, the average plastic used in each car is 100-130kg, of which about 4-6kg is EPP plastic).

In addition, EPP is also a good material for making aviation models, but the price is also an important reason limiting model enthusiasts from making EPP aviation models themselves.

2. EPS, polystyrene, is made through processes such as pre development, curing, molding, drying, and cutting. It can not only be made into foam plastic products with different densities and shapes, but also produce foam plates with different thicknesses. Widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting and other fields.
