Ethylene vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. It is highly elastic with rubber-like qualities, yet extremely tough, which makes it a popular choice for all types of flexible tubing. In many cases, EVA extrusions offer a more cost-effective alternative to rubber.
EVA is flexible even at low temperatures and is three times as flexible as low-density polyethylene (LDPE). It offers low and moderate temperature toughness, good chemical-resistance, exceptional clarity and gloss with little or no odour, and its resilience prevents cracks from appearing.
EVA extrusions are available in a range of hardnesses. The higher the vinyl acetate content, the more flexible and transparent the finished product will be.
EVA extrusions in use
Many products can be produced from extruded EVA, including:
- Medical tubing
- Drinks and beer tubing
- Cleaner hosing
- Anti-vibration pads
