EVATHENE® UE649-04

Ethylene Vinyl Acetate Copolymer
USI Corporation
产品说明:
EVATHENE UE649-04 is a high flowability and medium VA content ethylene vinyl acetate copolymer (EVA) with many excellent properties, such as characteristic flexibility and elasticity, thermal stability, good low temperature resistance, good compatibility, resistance to blocking and non-toxicity, etc.
It possesses excellent heat stability, flexibility and good compatibility with tackifier resins and petroleum wax. The characteristics stated make EVATHENE UE649-04 to be the popular one of EVA for making hot melt.
The hot melt made by EVATHENE UE649-04 adheres with other materials which possess good adhesive strength, easy coating and non-solvent fit the request of environment protection and the hot melt is suitable for packaging, wood-working and other product assemblies.
