Ethylene Vinyl Acetate (EVA)
Ethylene vinyl acetate (also known as EVA) is the co-polymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene.I t is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive water proof properties, and resistance to UV radiation.EVA slippers and sandals are currently very popular because of their properties like light weight, easy to mold, odorless, glossy finish, and cheaper compared to natural rubber. EVA resins are available in a broad range of specialty grades designed for consistent performance and productivity.
