38 Degree To 70 Degrees Hardness EVA Material Ethylene Vinyl Acetate Foam
EVA refers to a foam material made of EVA and low-density polyethylene as raw materials, and other additives are added through molding foaming or injection molding foaming. EVA material is made from the copolymerization of ethylene and vinyl acetate. The English name is EthyleneVinylAcetate, or EVA for short.
EVA foam materials have excellent chemical properties and are widely used in the manufacture of shoe materials, EVA luggage linings, sporting goods materials EVA tool kits, building materials, and various emerging applications such as electronic accessories and automotive interiors.

FAQ:
Q1:What's the physical properties of EVA foam?
EVA foam is quite versatile when it comes to physical properties. Its hardness levels can vary from 15 to 80 degrees on the Shore C scale. Additionally, its density can range from as low as 33 kg/m³ to as high as 280 kg/m³.
Q2:What's the relationship between hardness and density of EVA foam?
EVA foam density is divided into three standards according to hardness:
1)High foaming hardness is 5%-40%,
2)Secondary foaming hardness is 40%-55%
3) Primary foaming hardness is 55%-75%,
Currently 38-60 °,Most used in packaging linings
