PTFE (Teflon) & Restructured PTFE Gaskets

For many years, PTFE has been recommended for a variety of sealing applications, particularly where chemical resistance is a critical factor. Macroseal stocks and produces many styles and thicknesses of PTFE and PTFE-added gaskets, sheets and gasket material. Standard PTFE sheets of virgin and repro are cut and shipped daily, as well as the glass-filled PTFE used in applications to decrease cold flow. Newer products in recent years have included restructured PTFE, such as the Gasket Resources (GRI) Durlon 9000 and 9200W, for use against more aggressive chemicals, and the Flexitallic Sigma line (Sigma 500, Sigma 511, Sigma 522/577, Sigma 533, Sigma 588, and Sigma 599), with a biaxially orientated structure, for use in the toughest applications.
