Closed Cell Black EVA Foam Inserts Packaging Jewelry Velvet Gift Box
EVA Foam is a soft form of rubbery foam, similar in firmness to a yoga mat, but a bit less spongy. EVA is often valued for its soft feel, strength in low-temperature environments, and resistance to cracking. It is also UV-resistant so can last a long time in applications that are exposed to sunlight.
Advantage:
1.Good elasticity and compression
2. Insulation
3. Shakeproof
4. Heat and noise reduction
5. Light weight and chemical resistant
6. Antibacterial
7. Waterproof
8. Nontoxic
9. Bright and colorful colors
10. Suitable for a wide temperature range

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 types of EVA Foam We Offer?
We provide a wide range of EVA foam products, including sheets, mats, and strips.
Our foam comes in various densities and resistance levels to suit different applications.
Q3:Is EVA foam a plasitc or rubber product?
EVA has the properties of both plastic and rubber, so it can be classified as a "semi-rubber" material.
Traditional plastics are mainly composed of carbon, hydrogen, oxygen and other elements,
while rubber is mainly composed of carbon, hydrogen, oxygen and nitrogen.
From a molecular structure perspective, EVA is quite different from traditional plastics and rubber,
which is one of the reasons for its classification controversy.
