Porous Teflon Sheet, coating low level of PTFE
Porous Teflon Sheet balance the porosity and release property, it has a higher porosity than normal PTFE coated fabrics, and this Teflon coated fabric combines fiberglass with low content of PTFE coating.
This Porous Teflon fabric is used in applications which need airflow pass throw the fabric under pressure (air circulation for drying and curing processes), normal applications including casting sheets for uncured elastomers, vacuum bag bleeder cloth for composite molding, luxury Vinyl tile manufacturing, release sheet for grinding wheels and so on.
Unlike PTFE premium series, it is more flexible, much stronger and can be wrapped around curved shapes.
Porous Teflon Sheet
After many years development, Youngsun offering Porous series with balanced PTFE content and enough porosity.
With this high porosity surface, this Porous Teflon Sheet can allow air circulate the fabric in the production such as vacuum bag bleeder cloth, which allow products to cure and out gas through fabric.
At the same time, Teflon content will make sure the easy release surface and high tensile strength. Youngsun will balance these two properties.
Applications of Porous PTFE coated fabrics
Because of these particular properties, this Porous PTFE fabric is excellent for using in a wide range of applications, from the manufacture of polymers to a release medium for composite molding process.
Applications of Porous Teflon Sheet:
★ Aerospace, Communications & Milltary, Composite mold release in vacuum bag, or use as release sheets for fabricating glass-resin structures.
★ Polymer Processing: Manufacture of silicone rubber sheets, Curing rubber and plastic foams and sponge.
★ Insulation and protection.
★ Release liner for grinding wheels.
★ Drying painted or lacquered products.
★ Release sheet for heat sealing machines
★ Release sheet or belts for Luxury Vinyl tile, PVC flooring
