EVA Explained
Ethylene-Vinyl Acetate (EVA) is the copolymer of ethylene (E) and vinyl acetate (VA). The VA content can vary by 10% to 60% depending on the properties required. A Higher VA content gives more rubber like qualities. We can offer a wide range of materials but keep in stock six grades. All offer rubber like qualities in softness and flexibility. All have a low compression set.
Properties
- Closed Cell.
- Resistance to UV.
- Good Buoyancy.
- Good recovery to original shape after compression.
- Many densities and colours available.
- Excellent for printing on.
Uses
- Shock Absorption in sports shoes and Orthotics.
- Childs Toys.
- Arts and Crafts.
- Sports Mats.
- Gaskets.
- Water Sports.
