Braskem EVA PN2021
乙烯醋酸乙烯共聚物
Braskem
產(chǎn)品說明:
PN2021 is an Ethylene-Vinyl Acetate (EVA) copolymer, mainly used for the production of crossbed/expanded plates and other parts. It is a product with easy processability and high compatibility with mineral fillers, other thermoplastic and elastomers. Other important characteristics are elasticity, flexibility, excellent stress cracking resistance (ESCR), chemical resistance, and low temperature strength. The exclusive morphologic characteristics give an outstanding crossbability. The components produced with PN2021 have the following properties: lightness, resistance to debation, low shrink, high capacity of sticking and retention of colors.
