Braskem EVA TN2020
乙烯醋酸乙烯共聚物
Braskem
產(chǎn)品說明:
TN2020 is an Ethylene-Vinyl Acetate (EVA) copolymer, developed to mostly meet the needs of the multi-layer packaging segment produced by coextrusion and/or lamination processes. Multilayer structures with TN2020 can be irradiated to improve physical proprieties, such as, adhesion between layers, puncture resistance and hot sealing. Since it presents an exceptional weldability, this product meets the requirements for automatic or semi-automatic lines of cutting, welding, and/or packaging (with or without vacuum-packed process). It has excellent perbance during the extrusion operation, thermal stability, and a low consumption of energy for its processing, rendering to package production a dimensional unibity and excellent visual properties with high transparency and gloss that enhance the printing and surface finish of the packaging.
