Braskem America SVT2180 is a copolymer of renewable ethylene with Vinyl Acetate (EVA) mainly used for the production of crosslinked foam sheets and other parts. It is a product with easy processability and high compatibility with mineral fillers, thermoplastics, and elastomeric resins. Other important characteristics are elasticity, flexibility, excellent stress cracking resistance (ESCR), chemical resistance, and low temperature strength. The exclusive morphologic characteristics give outstanding crosslinkability. The components produced with SVT2180 have the following properties: low weight, resistance to deformation, low shrinkage, high capacity of shrinkage, and color retention. The minimum biobased carbon content of this grade is 80%, determined according to ASTM D6866.
