Thermodyn Corp.

In 1979, Thermodyn began business with the dual purpose of selling A.W. Chesterton products and manufacturing high-temperature elastomers for the expansion joint industry. Today, that is still our main focus. Fluoroelastomers made by Dupont Dow and 3M, Dyneon are our specialty, but all elastomers and coated products are within our realm of expertise. With the addition of Teflon®-coated and filmed fiberglass products, and our patented Fluorodyn Caulk and Coating made with Viton®, we have a complete line for the expansion joint, gasket, and fluid sealing industries.

We are leaders in manufacturing new and innovative products used around the world.
