Adhesive Backed EVA Foam Sheet Waterproof Protective Material For Seal Gasket
EVA foam also known as Ethylene-Vinyl Acetate foam is a closed cell material that usually comes in large sheets. EVA foam is UV resistant and is often used for hot tub insulation, gym mats, fishing rods, soccer cleats and even biomedical drug delivery devices. EVA is also tear resistant and has fantastic shock absorption properties
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
