PTFE Coated Fabrics
PTFE fabrics, or heat sealing fabrics, consist of a woven fiberglass and are coated with a PTFE resin. They are extremely resistant to high temperatures, contain outstanding electrical properties, have excellent release surfaces and superior chemical resistance.
Fabric grades include Standard, Premium, Mechanical, Economy, Porus Bleeder & Filter Cloth, Crease & Tear Resistant, Black Anti-Static, Open Mesh and Silicone Rubber Coated Fabrics.
Premium Grade PTFE – Glass Fabric
Premium Grade PTFE-Glass Fabric offers optimum release and durability in harsh environments. Applications include reusable pan liners for cooking and baking, laminate separator sheets, tortilla and pizza crust belts, heat sealing and applications where fabric weave impression is undesirable.
Standard Grade PTFE – Glass Fabric
Standard Grade PTFE-Glass Fabric is used in the widest range of applications due to its combination of high performance and moderate price. Applications include release sheets on heat-sealing machines and laminate presses, release surface for paints, adhesives and food products, gaskets, seals and bearings for chemicals, oils, and gases, thermal insulation for high temperature and chemical resistant applications and covers on hot platens, chutes, hoppers and troughs.
Mechanical Grade PTFE – Glass Fabric
Mechanical Grade PTFE-Glass Fabric is preferred in applications where economy is more important than maximum resistance to chemicals and solvents. Applications include chemical resistant laboratory aprons, protective curtains for paint spraying and bottle washing, acid protection and food packaging.
Economy Grade PTFE – Glass Fabric
Economy Grade PTFE-Glass Fabric is designed for large volume applications that require cost-efficiency and high performance. Applications include leaders for processing paper, plastics, metallic foils and cloth, separator sheets for processing uncured rubber and manufacturing of abrasive wheels.
Porous Bleeder & Filter Cloth
Porous Bleeder & Filter Cloth promotes drying by allowing airflow through the fabric. It is used as a release cloth in vacuum molding, filtration, strainers and pollution abatement.
Crease & Tear Resistant PTFE – Glass Fabric
Offers a cost effective solution to FPC assembly over conventional methods. Polyimide tapes, resin coated plates and double sided tapes can increase costs, lower productivity, contaminate and/or damage flexible circuitry, reduce print accuracy and create environmental issues.
Black Anti-Static/Conductive Fabric
Specially treated fabric that reduces static build up. It can be provided with carbon loading which offers semi-conductive and anti-static properties.
Silicone Rubber Coated Fabric
Silicone Rubber Coated Fabric offers a tough coated surface for applications where high flexibility and a high slip coefficient are required. It is an excellent electrical insulator in harsh environments, has high resistance to mild alkali, non-oxidizing acids, most salts, mineral lubricating oil, air, moisture and sunlight and it will release adhesive and viscous materials which often adhere to a fluorocarbon resin. Applications for silicone coated fabric include electrical insulation tapes, gaskets, heater covers, safety curtains, conveyor belts for industrial processes, foam manufacturing, shrink tunnels and release and separator sheets for viscous processes in the chemical, rubber, plastic, electrical and aerospace industries.
Open Mesh Fabrics
Are often used in the creation of belts because they allow outgassing of volatile products and promote drying by allowing airflow through the belt. These belts are ideal for drying, curing and bonding inks, pigments and powders to fabrics and non-woven materials.
