Informação do produto
Styroflex® 2G66 is a styrene-butadiene block copolymer (SBC) with the properties of a thermoplastic elastomer (S-TPE). Styroflex® 2G66 is the only S-TPE with a styrene content of at least 60 % styrene and a rubber fraction of at least 70 %. Characteristic properties of Styroflex® 2G66 are therefore: high transparency, excellent thermostability, very high elongation at break and high resilence. Styroflex® 2G66 is more polar than comparable SBS or SEBS grades and offers a good printability.
Applications: Styroflex® 2G66 is a very versatile material, suitable for a variety of applications: In multilayer (coextruded with PE-EVA), thin-gauge film for the supporting layer, Styroflex® 2G66 is used e.g. for packaging fresh meat. Styroflex® 2G66 is also used for the modification of styrenic polymers; e.g. blended with high impact polystyrene it improves the toughness and the stress cracking resistance (ESCR) significantly. Styroflex® 2G66 is also suited for two-component injection molding, especially with polystyrene, to which it has excellent adhesion. Styroflex® 2G66 and compounds based on Styroflex® may be used for conventional injection molding (eg. of toys) and the extrusion of profiles, flexible tubing and soft foams.
