Popularity:7551Publication time:2019-9-2

EVA foam has many unparalleled advantages compared with other materials. What is Eva? What is the difference between ordinary foam materials and ordinary foam materials? Why do manufacturers like to use EVA materials? The reason is that compared with other materials, EVA materials have many incomparable advantages.

EVA, also known as ethylene-vinyl acetate copolymer material, is a new type of environmental friendly plastic foaming material. EVA material products are generally well-made, with good cushioning, shock-proof, heat insulation, moisture-proof, chemical corrosion resistance and other advantages, and the surface is non-toxic, non-absorbent and soft. Tensile toughness is stronger than low density polyethylene, but the surface is not bonded. White transparent, high feeling, feel similar to PVC film. It should be distinguished. Eva foaming material has good economic benefits, especially the single cross-linking foaming technology has the advantages of industrial continuity, short production cycle and saving raw materials. Point.

EVA is widely used in our daily production and life, such as antistatic EVA, high elasticity EVA, tasteless EVA, etc. This is even more confusing for those who are not professionals in this field in their daily lives.

Advantages of EVA foamed cotton:
1. Biodegradable: When discarded or burned, it will not cause harm to the environment.

2. The price is similar to that of PVC: EVA is more expensive than toxic PVC, but cheaper than PVC without phthalates.

Three. Light weight: EVA density is 0.91-0.93, PVC density is 1.32.

4. No odor: EVA does not contain organic odor, such as ammonia or other organic odor.

5. No heavy metals: in accordance with relevant international toy regulations (EN-71 Part 3 and ASTM-F963).

6. No Phthalates: For children's toys, there is no risk of release of plasticizers.

7. High transparency, flexibility and toughness: wide application range.

8. Ultra-low temperature resistance (-70C): Suitable for ice environment.

9. Water, salt and other substances: can be maintained in a large number of applications.

Through the above introduction of EVA foam, I hope to help you.
