General purpose materials are used for applications that may not require specific certifications. With such a wide range of uses and applications, our general purpose materials may be exactly what you need for your parts.


One of the materials that Sherwood Industries Inc. extrudes is made with Santoprene™ Thermoplastic Vulcanizate (TPV) from Celanese. Santoprene TPV is a blend of polypropylene and EPDM rubber meaning it behaves like a rubber but processes like a thermoplastic. This material is a high performance elastomer that provides consistent performance and chemical resistance. Most of the general purpose grades are certified for multiple UL ratings, RoHS compliant, and automotive certifications. These automotive certifications include requirements from General Motors, Ford, and other automotive manufacturers.

Santoprene TPV possesses some of the best flex-fatigue resistance in the thermoplastic elastomer (TPE) family. It offers long-term durability and outstanding dimensional stability to your finished part. Santoprene TPV also has a very low compression set, which means it withstands pressure well and will resist permanent deformation. It is common that Tier 1 automotive manufacturers have weight guidelines for each part, Santoprene TPV can reduce weight up to 30% compared to its EPDM rubber counterparts. Santoprene TPV is also produced at a lower cost than thermoset rubber.

General purpose grades of Santoprene TPV can be used in a variety of industries including automotive, building, construction, household, and electronics. It can be used in both consumer and industrial applications in products such as seals, gaskets, dampeners, tubing, plugs, mats and more.


We can extrude sheet from 0.020” to 0.250” (0.6 mm to 6.3mm) thick. We offer widths between 6” to 36”. Our extruded sheet can be wound onto 3″ or 6″ PVC cores. Our machinery allows for flexibility on the amount of linear feet wound on each roll or a certain weight limit per roll. With four patterns and color matching capabilities, we can provide you with a customized product for your application. We can accommodate orders ranging from 500 pounds to truckloads, shipped worldwide.

We also offer profile extrusion to provide shapes and configurations to match your products’ exact requirements for your unique application. We make custom dies to extrude a shape that fits your requirements and will assure a consistent and reliable part over years of extrusion. Profile parts can be cut to length or wound into a roll.
