WEB EXCLUSIVE: The newest EPS resin from Nova Chemicals, Monaca, Pa., is a shape/packaging grade, R625B, with 25% recycled content. The recycled PS used in this product is EcoSix resin from RAPAC, a RING Company, Oakland, Tenn.
Nova’s R625B EPS boasts a low VOC content of around 4%, minimum foam density of 1.2 pcf, fast molding cycles, and excellent fusion and part strength. It can be used for the same applications as a virgin EPS resin; its quality and consistency are said to be similar to its virgin counterparts and to surpass that of other EPS resins with recycled content. Applications include general-purpose packaging, coolers, wine-packs, medical/pharmaceutical shippers, and custom-shape molding.
RAPAC collects and processes EPS and other PS materials into PS beads ready for pentane impregnation by Nova Chemicals. According to Nova, its unique resin manufacturing allows the RAPAC recycled resin and the Nova virgin PS resin to be homogenized in the reactor prior to adding pentane, creating a highly consistent R625B resin.
