FlameShield™ This high temperature, heat resistant and chemical resistant fabric with self adhesive backing and a release film is used in packaging as a non-stick release surface on heat sealers, blister and form fill sealing equipment. Used on guide rails chutes and slides. Excellent resistance to almost all solvents, caustics and acids. High dielectric strength.
Used as an insulation buffer for RF sealing, and as a surface cover on L Bar, Impulse and Bag sealers. This material is a tan color.
The base fiberglass fabric is rated to 1000°F / 537°C, while the PTFE coating melting point is 620°F / 327°C.
Available in 5 weights / thicknesses, in roll widths of 39" in a roll length of 36 yards. (Adhesive thickness is extra (add .0017").

The PTFE resin is applied to the fabric in a hot process and under pressure, causing a total impregnation of the base fabric. The surface of the resin is smooth and it takes considerable and aggressive force to scratch the ptfe surface to remove it from the fabric with fingernail scraping.
Available in Standard and Premium grades. Premium grade has an almost perfectly smooth surface while standard grade surface has some profiling of the underlying base fabric. Available with Silicone or Acrylic adhesive.
