Saint-Gobain® CHR® Pressure Sensitive Adhesive Tapes are available in a wide range of backing types and backing thicknesses. They can be provided with Silicone, Acrylic, or Rubber adhesives tailored to the application needs. Among the most popular backings are fiberglass, silicone coated fiberglass, PTFE, PTFE coated fiberglass, UHMW polyethylene, polyimide, polyester, cloth/textiles, copper and aluminum, and composite backings. These tapes are used in electrical insulation markets, aerospace markets, industrial anti-stick and release markets, and electronic manufacturing markets where high temperature specifications and high performance engineering designs require high performance tapes. Acrylic (A) Acrylic adhesives perform in continuous operating temperatures from -40°F to +375°F (-40°C to +188°C). Benefits include exceptional solvent resistance, excellent adhesion to metal, superior weathering and aging characteristics. Rubber (R) Natural rubber adhesives impart high tack and shear characteristics. These adhesives perform in continuous operating temperatures from -20°F to +325°F (-29°C to +164°C). Natural rubber adhesives have a broad range of adhesion performance from 3.0 oz. /in. to 60 oz. in. Silicone (S) Perfect for extreme temperature applications, silicone adhesives perform in continuous operating temperatures from -100°F to 500°F (-73°C to 260°C). Silicone based adhesive systems exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue. BACKING SUBSTRATES Film-FEP FEP film is used for applications requiring optical clarity, quick release, and abrasion resistance. FEP film applications include high temperature coil and capacitor wrapping, composite bonding, masking, and conveyor release linings. Film-Polyester Polyester films have excellent dimensional stability, high tensile, tear, and impact strengths, and ultimate elongation up to 120% of its original dimensions. These films exhibit low water absorption and good resistance to oils, greases, strong acids, and organic solvents. They also retain electrical properties, dielectric strength and dielectric constant in continuous operating temperatures from -100°F to 350°F (-73°C to 177°C). Applications include transformer and capacitor wrapping, printed circuit board fabrication, splicing tapes, composite bonding protection, and low-cost masking. Film-Polyimide Polyimide films are employed because of their extreme heat resistance. Service temperatures range from -100°F to +500°F (-73°C to +260°C). These flame retardant films exhibit high tensile strength and conformability, good solvent resistance, excellent dielectric strength and good abrasion resistance. Polyimide tape applications include electrical insulation, capacitor, transformer, and coil wrapping, well, electronic assembly, and wave solder protection. Film-PTFE PTFE films provide a conformable release surface and exhibit a remarkably low coefficient of friction and non-stick properties. PTFE films have high temperature resistance and are virtually unaffected by all chemicals. At elevated temperatures, PTFE film still retains excellent tensile strength. Service temperatures range from -100°F to +500°F (-73°F to +260°C). Film applications include high temperature coil and capacitor wrapping, composite bonding, masking, and conveyor release linings. Film-Rulon® Rulon films offer superior abrasion resistance when compared to conventional PTFE films. Service temperatures range from -100°F to 500°F (-73°C to +260°C). In rotating bearing tests, it provided a 500-fold increase in wear resistance over standard PTFE. Applications include bearing liners, chute and guide rail coverings. Film-UHMW UHMW polyolefin film tape provides anti-sticking and abrasion resistance properties for application temperatures ranging from -100°F to 225°F (-73°C to +107°C). Applications include bearings, chute and guide rail coverings. Glass-Cloth Glass cloth offers excellent abrasion resistance and mechanical properties, as well as high tensile strength and extreme temperature resistance. Service temperatures range from -100°F to +500°F (-73°C to 260°C). Highly conformable and flexible, glass cloth has the unique ability to absorb insulating varnishes, which makes them an excellent choice in the electrical market. Applications include electrical insulation, coil and motor wrappings, and general industrial applications. Glass-PTFE PTFE glass provide dimensional stability, high tensile strength and edge tear, operates over a temperature range from -100°F to +500°F (-73°C to +260°C), and offers better abrasion resistance than uncoated glass cloth. The PTFE surface offers quick release and chemical resistance characteristics. Anti-static PTFE glass yields improved thermal conductivity and static dissipation. Available with silicone or acrylic adhesives, PTFE glass applications include heat sealing and low friction release surface liners for conveyors.
