Black And White High Density EVA Foam Ethylene-Vinyl Acetate Foam For DIY Cosplay
The production process of EVA foam materials mainly includes three steps: granulation, blending and foaming. The EVA granulator crushes and processes EVA into sufficiently fine particles, and then the EVA foam material manufacturer blends it with other additive particles according to a certain ratio. Different formula materials can produce EVA foam with different properties after foaming. Material.
● Foam material manufacturers then sell to EVA foam product manufacturers to produce application products, such as shoe materials. The scraps generated during the production of foam materials can also be recycled and processed to produce recycled EVA foam materials.
● Recycling and utilizing recycled EVA foam materials is not only beneficial to environmental protection, but also helps companies control and reduce production costs. At present, there are not many companies in China that have mastered the technology of recycling recycled EVA foam materials, especially those that can produce recycled materials with stable quality.

FAQ:
Q1:How to classify EVA foam according to hardness?
1)High elastic EVA:15-25°
2)Ordinary EVA:38°
3)Medium density EVA:45-60°
4)High density EVA:65-80°
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
