HECO® FOAM 940 S

HECO® FOAM 940 S by HECOPLAST is a 40% endothermic system on a PS carrier. Acts as a blowing and nucleating agent. It has a starting temperature of about 150°C. The optimum gas yield will be achieved at 190-230 °C. It provides an optimal distribution in all kind of blowing processes that is reflected in finely structured foams and optimized cell size as well as in distribution. It is used in injection molding and extrusion of PS, ABS and other styrenic polymers. HECO® FOAM 940 S recommended dosage for injection molded parts is 0.3-0.6% to avoid sink marks 0.3-0.6%, for direct gasification, physicochemical foaming, ie cell nucleation is 1.2-2.0% and for weight reduction is 2.0-2.5%. It complies with EU-RL 1272/2008, EU-RL 10/2011 (ff) and US-FDA. It has a shelf life of 12 months.
