PTFE Glass Fabrics

PTFE glass fabrics consist of a woven fiberglass that has been coated with a PTFE resin. They are designed for a wide range of applications and come in several grades to meet specific performance requirements. These fabrics have a nonstick surface, perform well under temperatures ranging from -100° F to 500° F. They also are chemically inert, have high tensile strength and have outstanding electrical properties. Typical applications include the heat-sealing or cutting of plastic bags or film, the manufacturing of dress shirts and blouses in the sizing process (to seal necks, collars and cuffs without damaging the fabric), thermal insulation, conveyor belts, gaskets, seals, bearing liners, and nonstick surfaces for paints, adhesives and food products. A variety of industries use PTFE glass fabrics, including packaging, aerospace, electronics and petroleum processing.

PTFE Glass Fabric Grades

Standard Grade PTFE Fabric

Standard grade PTFE fabric has a smooth surface and excellent nonstick properties. It serves the widest range of applications among the PTFE fabric grades. Standard grade contains an excellent balance of substrate weave, strength, finish and coating weight. Typical applications include release sheets on heat-sealing machines and laminate presses; nonstick surfaces for paints, adhesives and food products; thermal insulation for high-temperature and chemical-resistant environments; gaskets, seals and bearings for chemicals, oils and gases; and covers for hot plates, platens, chutes and hoppers.

Premium Grade PTFE Fabric

Premium grade PTFE fabric is more durable than the standard grade. It has an extra-heavy coating of PTFE resin and a super-smooth, nonporous surface suitable for advanced applications such as release sheets for cooking and baking, laminate separator sheets, specialized heat-sealing, and demanding, nonstick applications. Other uses include motor and generator insulation, conveyor belts, gaskets, seals, and bearing liners.

Mechanical Grade PTFE Fabric

Mechanical grade PTFE fabric has a medium coating of PTFE designed for resistance to high temperatures and chemicals. It also has excellent dimensional stability. Typical applications include chemical-resistant laboratory aprons and protective curtains such as those for bottle washers, food packaging and acid protection, and other low-load mechanical applications.

Economy Grade PTFE Fabric

Economy grade PTFE fabric has a light coating of PTFE and is designed for large-volume, high-performance applications. The cost-efficiency of economy grade PTFE fabric does not compromise the quality of the product. Typical applications include leaders for processing paper, plastics, metallic foils and cloth; separator sheets for processing uncured rubber; and the manufacture of abrasive wheels.

Porous Grade PTFE Fabric

Porous grade PTFE fabric is designed for airflow, outgassing and resin bleed-through. It uses open-mesh glass fabric with a coating of PTFE that ranges from breathing to 0.25- inch mesh. This grade also has excellent resistance to chemicals. Typical uses include filtration, release sheets for fabric coating, the curing of rubber and plastic foams, and applications that require draining or drying.

PTFE Adhesive Tapes

PTFE adhesive tapes come with a high-quality silicone or acrylic adhesive for outstanding performance. The PFTE coating provides optimal release, dimensional stability and outstanding heat resistance (silicone, 500° F; acrylic, 350° F). PTFE adhesive tapes have low friction and function well as electrical insulation.

PTFE Glass Tape

This pressure-sensitive tape, which comes with either a silicone or an acrylic adhesive, has a PFTE coating that offers excellent heat resistance, strength, dimensional stability, a nonstick surface and exceptional wear life. Two grades are available: standard and premium. Standard grade is the preferred choice for most adhesive applications. It has a smooth surface and outstanding nonstick properties. Premium grade has an even smoother surface and can meet the needs of even the most demanding applications.

PTFE Glass Zone Tape

PTFE glass zone tape is a double-sided tape used to create custom adhesive zones. The adhesive is available in either silicone or acrylic.

PTFE Glass Cloth Tape

PTFE glass cloth tape is available with adhesive on one or both sides of the tape. It is intended for use in masking parts for plasma spraying and for inner and outer wraps for transformers and motors. This tape has good abrasion resistance, outstanding flexibility and stability at high temperatures.

Skived PTFE Tape

Skived PTFE tape has broad acceptance in both military and industrial applications. Its high elongation properties make it an ideal choice when conformity is important. Skived PTFE tape is an excellent choice for wire wrap and insulation tape for high-dielectric and high-temperature applications. With mechanical operations, skived PTFE tape serves as a multipurpose tape, given its low friction and nonstick properties.

PFTE Belting

PFTE belting can be manufactured to custom specifications, depending on individual needs. These specifications are determined from information provided on temperature range (-100° F to 500° F) needed for continuous operation, pliability, release qualities (surface finishes) and strength. The amount of pliability needed for a belt is based on the size of the belt roller. The smaller the roller, the more flexible the belt must be. Thinner materials (0.010 inches and under) are more pliant than heavier coated fabrics. Surface finishes can range from rough and semiporous to super smooth. The release needed for fabric impressions helps to determine the type of surface finish selected. Factors influencing belt strength include breaking, tensile and tear strength. Other considerations include the amount of load the belt will carry, how fast it moves and the tightness of the belt tension. Several splice options are available, including alligator, clipper, smartloop, fabric-notch, butt, overlap and scarfed. Belts also can be equipped with heat-sealed film or fabric on one or both edges of the belt. The reinforcement reduces fraying of the belt edges that rub on guiding rollers and provides a strong anchor for guiding pins, snaps and grommets. Tracking and guiding devices can be placed on one or both edges of the belt. Options include snaps, grommets and silicone-rubber guides. Two-ply belts, laminated with staggered splices, work well when continuous thickness along the entire length of the belt is needed. This type of belt ensures a uniform seal for packaging and heat-sealing operations.
