Rubber Material Science at Boyd

Rubber is an elastic polymeric substance that can be either natural or synthetic. It can regain its original shape within limits after being deformed if not vulcanized. Vulcanizing rubber adds strength. Rubber is generally tough, resilient, and resistant to environmental and chemical exposure. It is used as a key ingredient in a wide variety of material formulations including sponge, foam, adhesives, and films in addition to traditionally recognized rubber components like hoses.

Boyd custom compounds, molds, extrudes, and converts rubber to produce resilient components that offer a variety of characteristics. Our rubber material science heritage dates 70+ years.

rubber compound prepared for production

Featured Rubber: Silicone

Boyd has been compounding and manufacturing silicone components for medical, eMobility, food, transportation, construction, and aerospace applications for over 40 years. Boyd’s high quality silicone processes enable us to produce silicone tubes, extruded profiles, o-rings and sheets to complex silicone molded parts and assembled products.
