Sherwood Industries began in 1975 with the developing of foams for use as Speaker Surrounds. Sherwood Industries Inc. has supplied the Speaker Industry worldwide with the highest quality foams for over 45 years now. We created specialized Polyester and Polyether foams including water resistant types that we 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. We continue to supply foams to all corners of the world. Continuing our product development, we started extruding Santoprene TPV Sheet for use as Speaker Surrounds. With this new product in our line-up, we needed more space and moved to our current facility in Niles, Illinois. We now produce Santoprene Sheet for a multitude of industries including Automotive, Electric, Medical, Appliances, etc. Santoprene is used in everything from Die Cut Gaskets to Speaker Surrounds. We then 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 extrude over a million pounds a year of Santoprene and other plastics. We are proud of our expansion and are not afraid to evolve and create new products to serve our customers
