Styrenic block copolymer. (Materials).

This grade of Septon hydrogenated styrenec block copolymer is claimed to offer better mechanical properties than previous versions of SEBS. Ideal applications for the polymer grade are said to include sports equipment, soft touch grips, handles and buttons, hardware and power tools. This polymer is said to be ideal for compounders seeking soft touch and good physical properties. Septon 4077 is a SEEPS polymer. Joined on either end by a polystyrene block, the midblock structure of SEEPS (polystyrene-poly [ethylene/ethylene/propylenel-polystyrene), a copolymer-like amorphous ethylene propylene rubber, allows for higher oil loadings and reduced oil migration when compounded with other resins like polypropylene. This material is compounded on traditional processing equipment like twin screw extruders, and processed by injection molding equipment and extrusion.
