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.
Benefit ::
- Low seal initiation temperature for fast packaging speeds
- Low shrink temperature
- Greater adhesion than polyethylene (PE) to a variety of substrates/layers including polyolefins, PVS, PS and PET
- Softer and clearer than PE
- Enhanced flexibility
- Increased impact strength
- Improved puncture resistance
- Excellent flex crack resistance
- Excellent flow and caulking in seal area
- Good bondage to PVdC in coextrusion processe
