Material Notes:
CN8092 is an Ethylene-Vinyl Acetate copolymer (EVA) which has a molecular structure that provides easy processing, adhesion, resilience, low hardness, good moisture, and gas barrier properties. It is a non-halogen resin that has excellent thermal stability and a low content of oligomers, with low influence on organoleptic properties of the products. The melt properties of this resin allow processability in cast film and tubular film equipment. It contains antioxidant additives. Its applications include: base resin for production of compounds for cap liners in carbonated beverages; compounds; and master batches.
