Ethylene vinyl acetate (EVA) copolymers are used in extrusion film processes for applications including packaging, surface protection and greenhouse covers, and in photovoltaic cell encapsulation. EVA copolymers are used in molded caps and seals, footwear and car interiors. They are the base polymer in many adhesive resin formulations and in wire and electrical cables compounding. For the hot-melt adhesive needed to hold pages and covers together in bookbinding applications, low to medium MI and high VA grades are used to maximize cohesive strength and flexibility.RXSOL EVA is an ethylene vinyl acetate copolymer with 18% VA.
RXSOL EVA can be used for blown or cast monolayer and coextruded films, or blended with other resins. Other grades can be used for molded or extruded liner seals inside plastic and metal bottle caps.
