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.
