Description: SEPTON® is a series of high performance thermoplastic rubbers developed by Kuraray Co. Ltd. using its unique isoprene technology. SEPTON® resins are a series of hydrogenated styrenic block copolymers, which exhibit rubber-like properties over a wide range of temperatures. SEPTON®'s characteristics include:Excellent Mechanical PropertiesGood WeatherabilityExcellent Low Temperature PropertiesExcellent Electrical PropertiesSuperior Heat ResistanceExcellent Chemical ResistanceLow ToxicitySEPTON® grades are available with a range of Shore A hardness of 35-95 and tensile strengths of 290-5600 psi. SEPTON® resins are highly extendible with fillers, resins and oils, which allows formulation of a variety of hardness for adhesives, sealants and various compounds. As an additive, SEPTON® resins can be used to improve toughness of a variety of plastics. Several SEPTON® grades have U.S. FDA and USP Class VI approval.SEPTON® has a versatile series of grades which can be used in numerous processing techniques such as blow molding, injection molding, extrusion, hot melt and solution coatings. SEPTON® resins are thermoplastics therefore, the scrap is recyclable without significant loss of properties.Formulation (parts by weight): SEPTON® 4055 - 100, Polypropylene - 75, Process Oil - 120, Antioxidant - 0.3 Information provided by The Kuraray Group.
