Balforon "C" Gasketing Material

Balforon “C” is a proprietary material developed to handle higher pressures and temperatures than standard PTFE products. It has been used extensively in pump and valve applications. Balforon “C” material exhibits lower deformation under load and reduced cold flow, both at room and elevated temperatures.

Balforon “C” gasketing material is asbestos-free. Its permeability to gasses and vapors is considerably lower than standard PTFE products. This gasket material absorbs no moisture and is non-stick and non-adhesive. In addition, this material can be molded and machined into virtually any shape or configuration.
