KWO® MultiTex® Tape

ePTFE gasket tape

KWO® MultiTex® tape is a high quality gasket material made from multidirectionally expanded PTFE. In the expansion process the PTFE material is biaxially stretched.

Thereby the lengthwise and crosswise cold-flow tendency is reduced, the tensile strength is increased and the recovery property is substantially improved. The flexible material adapts excellently to the sealing surfaces and compensates for considerable unevenness, even at changing temperatures and loads. Another advantage of the material is that the seal tape is merely compressed but not widened during installation. The self-adhesive tape is easy to position.
KWO® MultiTex® gasket tape ensures always an excellent tightness under operating conditions. The product has very good recovery properties and a low leakage coefficient, even at reduced sealing pressure.
KWO® MultiTex® gaskets are suitable for all applications in which the high resistance of the PTFE material is required and where conventional gasket tapes reach their limits. The tape is characterised by an almost full chemical resistance and is suitable for temperatures of up to 230°C.
