SEPTON™ comprises a wide range of high-performance TPE raw materials based on our proprietary isoprene technology. These products are hydrogenated diblock and triblock styrene copolymers that have the same properties as rubber over a broad temperature range. The polymers are rigid before they are processed, but they soften during processing, giving good flow properties. During cooling polystyrene domains are formed and lock the elastomeric network together. SEPTON therefore has high tensile strength and good elasticity. Moreover, its thermoplastic properties make it is easy to recycle.
