SEPTON™ 8076 is a SEBS styrenic thermoplastic elastomer from Kuraray, a block copolymer with styrene hard segments and diene soft segments. It shows rubber-like elasticity over a wide temperature range, is plastic-like processable upon heating, and features excellent heat, weather, chemical resistance and high electrical insulation for diverse modification and formulation.
Composed of styrene hard segments and diene soft segments, with excellent rubber-like elasticity in a wide temperature range and melt processability.
Superior heat, weather and chemical resistance, as well as high electrical insulation, adapting to various harsh application environments.
Blended with polyolefins and process oil to make soft materials, an ideal alternative to vulcanized rubber and vinyl chloride.
Compounded with tackifying resin and process oil to prepare adhesives with outstanding heat and weather resistance for multi-scenario bonding.
Improves physical properties such as impact strength of olefin plastics, and acts as a high-efficiency compatibilizer for olefin and styrene resins.
Automotive and electrical components, utilizing its excellent elasticity, electrical insulation and resistance to harsh working conditions.
Daily necessities including stationery pens, toys and sporting goods, as a soft and durable substitute for traditional vulcanized rubber.
Adhesive industry, for formulating heat and weather resistant pressure-sensitive adhesives and structural adhesives for industrial bonding.
Olefin plastic modification, effectively improving the toughness and impact resistance of PP, PE and other polyolefin materials.
Polymer blending system, serving as a compatibilizer to realize efficient compatibility of olefin and styrene resin composites.
