EPP is short for a new type of foam. EPP is a polypropylene plastic foam material, a highly crystalline polymer/gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing environmental protection new type of pressure-resistant cushioning and thermal insulation material. EPP is also an environmentally friendly material, which can be recycled and reused, and can be degraded naturally without causing white pollution.

EPP has light specific gravity, good elasticity, shock and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, no water absorption, insulation, heat resistance (-40~130℃), non-toxic Odorless, 100% recyclable and almost no degradation in performance, it is a truly environmentally friendly foam. EPP beads can be molded into EPP products of various shapes in the mold of the Forming Machine.

EPP is widely used in automobiles, such as bumper core materials, anti-collision blocks, roof linings, door filling, headrests, sun visors, etc., which can save fuel consumption and improve passenger safety.

EPP has been widely used in the packaging industry, such as electronic products, medical equipment, etc., especially in the packaging of export products, and has become an irreplaceable packaging material in response to environmental requirements. Because of its non-toxicity and high temperature resistance, it is also widely used in food packaging and microwave heating.

Production principle

Generally, EPP beads must be pressure-loaded in a pressure tank (even if the beads are filled with a certain pressure of air), and then compressed air is injected into the mold of the EPP molding machine through a spray gun, and steam is injected to further expand the EPP beads And the surface is welded together to form. After cooling, the mold is stabilized at a certain temperature to obtain EPP products.
