CMD also includes in its production range gaskets made of various thermoplastic materials whose resistance characteristics are well known largely in chemical environments.

Specifically, for polytetrafluoroethylene (PTFE) gaskets, CMD uses both pure state and application-specific material. In types called filled, the characteristics are modified by the introduction of appropriate additive powders such as glass fibers, carbon, graphite, molybdenum disulfide, bronze, ceramics, and even mixtures of two or more powders.
