Sherwood Industries began in 1975, developing foams for use as speaker surrounds. Sherwood Industries Inc. has supplied the speaker industry worldwide with the highest quality foams for over 47 years now. We created specialized Polyester and Polyether foams designed specifically for use as speaker surrounds. Within a year of our inception, our U.S. sales grew, and we began exporting our foams to Japan, Taiwan, Korea, Europe and other countries around the world.

Continuing our product development, we started extruding Santoprene TPV sheet for use as speaker surrounds. Our Santoprene market quickly expanded to include automotive parts, building & construction materials, household appliances, electrical & energy products, and medical applications. As we grew, we needed more space and moved to our current facility in Niles, Illinois. We now produce over a million pounds of Santoprene sheet each year and continue to provide Santoprene sheet to markets worldwide. We have now expanded to include a profile extrusion line and a recycled rubber line, to complement our foam products and Santoprene sheet extrusion.

With 4 full time extrusion lines, we are happy to serve our many customers with superior products and great customer service. We are proud of our expansion and are not afraid to evolve and create new products to serve our customers.

Please call us and let us know how we can serve you. It is our pleasure to do so.
