What is EPP foam?

Let me popularize it with everyone. EPP is the abbreviation of expanded polypropylene (Expanded polypropylene), which is the abbreviation of a new type of foam plastic. EPP is a polypropylene plastic foam material. It is a highly crystalline polymer/gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing environmentally friendly new pressure-resistant buffer heat insulation material. EPP is also an environmentally friendly material, which can be recycled and reused, and can be naturally degraded without causing white pollution.

This is something that has become popular in recent years.
Epp Foam material is also one of the foam materials, but it is a more popular material in recent years. His focus is on environmental protection, good endurance, toughness, etc.
Generally we see Meituan Waimai or Baidu Waimai or some KFC, McDonald`s and other food delivery foam boxes, which are generally called EPP takeaway boxes in the industry, distribution boxes, and food insulation boxes can be delivered hot and cold; they can also be used in logistics. In terms of turnover, in terms of medicine, it can be used to distribute medicines.

EPP has light specific gravity, good elasticity, shock resistance and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance (-40~130°C), non-toxic Odorless, 100% recyclable with virtually no loss of performance, it is a true environmentally friendly foam. EPP beads can be molded into various shapes of EPP products in the mold of the molding machine. EPP is widely used in automobiles, such as bumper core materials, anti-collision blocks, roof linings, door fillers, headrests, sun visors, etc., which can save fuel consumption and improve the safety factor of passengers. EPP has been widely used in the packaging industry, such as electronic products, medical equipment, etc., especially in the packaging of export products, it has become an irreplaceable packaging in response to environmental protection requirements. Due to its non-toxicity and high temperature resistance, it is also widely used in food packaging and microwave heating.

Generally, the EPP beads should be loaded in the pressure tank first (even if the beads are filled with a certain pressure of air), and then the compressed air is injected into the mold of the EPP molding machine through the spray gun, and the 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.
