EVATHENE® UE659

Ethylene Vinyl Acetate Copolymer

USI Corporation

产品说明：

EVATHENE UE659 is a high VA content ethylene vinyl acetate copolymer (EVA) with excellent low temperature impact strength, environmental stress crack resistance, flexibility, elasticity, transparency, and processability. It could be developed for many new applications and substitute for flexible PVC,
rubbers, and other elastomers. One of major application of UE659 is mixed with blowing agent and cross-linking agent for compression molding or injection molding of foamed shoe sole. Another major application of UE659 is to mix with tackifier and PE wax to make hot melt adhesive. Besides, UE659 could be processed by injection molding, and extrusion while incorporated with additives.
