Americhem’s Sevrene® styrenic block copolymers represent years of compounding solutions developed to help extruders, injection and blow molders realize the efficiencies of thermoplastic elastomers (TPEs) with distinct structural advantages. Sevrene® can be customized for ideal stiffness and resistance to heat, ozone and UV light. Compared to traditional thermoplastic vulcanizates (TPVs), Sevrene® delivers better processing and appearance due to its all-thermoplastic, tri-block system. Greater tear strength – especially at durometers 55 Shore A and below – can also be expected from our custom colorable polymers that consistently outperform off-the-shelf products.

Americhem knows how to bring textures alive. We can modify our Sevrene® formulations to create the haptics, or surface feel, that your customers expect from a high-quality product. Whether you are aiming for slippery, smooth or sure-grip comfort, the rubber-like characteristics of styrene block copolymers allow us to improve tactile experiences for increased satisfaction.
No other SBC manufacturer understands the visual discipline of color like Americhem. Our color technology leadership can be utilized to access a wide range of highly weatherable colors for both interior and exterior applications. We know that color plays a decisive role in your customers’ selection process, and we will work with your design team to help boost creativity within our Sevrene® offering.
Sevrene® is an all-thermoplastic tri-block compound that is produced by combining styrene-ethylene-butylene-styrene (SEBS) rubber, polypropylene and oil in a twin-screw extruder. Other raw materials, such as filler, colorant, lubricants, compatibilizers and haptic agents can also be added to achieve the desired end-product characteristics. Americhem supplies Sevrene® in easy-to-process pellets delivered in bulk or in gaylords. Because SBC polymers have good chemical resistance to water, acids and bases but poor resistance to hydrocarbon-based oils, fuels and solvents, our material science experts will collaborate to ensure that Sevrene® thermoplastic compounds are the most suitable for your application.
