GYLON EPIX® Style 3504 is a high performance, aluminosilicate microsphere filled PTFE sheet material designed for use in many acids, some caustics, as well as hydrocarbons, refrigerants, and more. GYLON EPIX® will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, GYLON EPIX® delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm). The hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force of the flange for improved sealability.
