Expansion Joint Materials

TacExpan expansion joint materials are designed to provide stress relief, absorb thermal expansion and shock, adjust for minor misalignments in duct work and isolate mechanical vibrations. TacExpan PTFE fabrics used in non-metallic expansion joints offer excellent chemical and temperature resistance, flexibility and minimal vibration fatigue in harsh environments. TacExpan is constructed by laminating PTFE coated fiberglass fabric with PTFE film on one or both sides. Expansion joint material composition is dependent on the specific demands of the application.
