What is EVA foam material

    1. Introduction

    EVA refers to a foamed material made from EVA and low-density polyethylene as raw materials, adding other additives and then molding foaming or injection foaming. EVA material is made by copolymerization of ethylene and vinyl acetate. The English name is EthyleneVinylAcetate, or EVA for short.

    EVA foam material has excellent chemical properties and is widely used in the manufacture of shoe materials, eva luggage linings, sporting goods materials EVA kits, building materials, and various emerging applications such as electronic accessories and automotive interiors.

    2. Industry chain

    ● The production process of EVA foam material mainly includes three steps of granulation, blending and foaming. The EVA granulator will crush and process the EVA into small enough particles, and then the EVA foaming material manufacturer will blend it with other auxiliary particles in a certain proportion. Different formulas can be foamed to produce EVA foams with different properties. material.

    ● The foam material manufacturer then sells to the EVA foam product manufacturer to produce application products, such as shoe materials. The leftover material produced in the foaming material production process can also be recycled and processed to produce recycled EVA foam material.

    ● Recycling recycled EVA foam materials is not only beneficial to environmental protection, but also helps enterprises control and reduce production costs. At present, there are not many domestic enterprises mastering the technology of recycling recycled EVA foam materials, especially those that can produce stable quality recycled materials.

    Eva foam material is widely used in shoemaking
