When PTFE (polytetrafluorethylene) was developed in 1938, its importance to industrial sealing was quickly recognized because of its tremendous chemical resistance.
While use of PTFE as a gasket material increased in industrial applications, complaints about certain properties surfaced: skive marks made initial sealing difficult, cold flow caused leakage and premature failure, and temperature/pressure cycling was a problem.
The GYLON® Style 3522 material is made of 100% pure PTFE with no fillers or additives, making the material ideal for the most demanding, high purity requirements. Industries such as food, pharmaceutical, semi-conductor, recognize the uniformity of GYLON® 3522 that makes it an ideal gasket choice for those critical applications that cannot risk process contamination or premature failure.
