We fabricate beater add gaskets from the following manufacturers:

Beater-addition gasket materials, or simply Beater Add for short, are made by proprietary manufacturing processes. Each Beater Add vendor has their own process but the general process is as follows: A select mixture of water, latex, fibers, fillers, and chemicals is formed into a slurry. The slurry is then run through specialized machinery that extracts the water, dries the mixture, compresses, and vulcanizes the material into a long continuous sheet. Sheets are rolled as a finished product from which gaskets are fabricated.

The selection of fibers, fillers, chemicals as well as the compression force produce a wide range of formulations. The main advantage of Beater Add is that it is inexpensive. A disadvantage is that operating temperature ranges may be limited.

Thermoseal’s Multi-Layer Technology materials provide both exceptional interfacial and interstitial seal-ability. Conformable outer layers prevent leakage between the gasket and flanges and a strong high density core provides structural support while preventing leakage through the gasket. Multi-Layer Technology materials are available in varied compounds to match your application requirements so you can tailor performance to your customer’s application.
