PTFE porous sheet YS9040P with high mechanical strength

PTFE porous sheet has good non stick property while maintain the porous property of fabric. And PTFE porous sheet YS9040P has high tensile strength since ESONE is using satin weaved fiberglass fabric as basic material, this porous fabric is widely use in flooring industry, carbon fiber composited industry, aerospace industry and others.

Porosity and non stick surface is two contradictory property in manufacturing PTFE porous fabric, if too much PTFE content, then the porosity will be reduced, on the contrary, the porosity will be increased if lower PTFE content, so it is very important to find the balance to offer best product for customer’s applications.

What’s more, PTFE content also affect the mechanical strength of PTFE fabric, it is because the strength of fiberglass will be reduced when coating PTFE in high temperature, so more times coating, then the strength will be weeker. In this case, ESONE is using special formula and coating ways to maintain high mechanical strength, in order to offer long lasting PTFE porous sheet.

ESONE high tensile porous Teflon sheet is the reliable partner for your application.

Applications of PTFE porous fabric YS9040P

• Carbon fiber Laptop

Without doubt, carbon fiber laptop is the lightest laptop in the world, this material can be used to build race cars, aircraft, road bike, sports equipment, musical instruments and many other things.

Comparing to aluminum, carbon fiber composite is much more strong and stiff while aluminum is a soft metal, carbon fiber has a lower density than aluminum also, it is commonly used in military and aircraft industry to meet the extreme high demanding request.

YS9040P is used as release sheet for carbon fiber composited, in order to resist the continuously high pressure and high temperature while maintain the easy release surface.

• Luxury Vinyl Tiles (LVT) manufacturing

Luxury Vinyl Tile is a fast growing market which is famous because of the durability and aesthetic appeal. It has many competitive properties than traditional flooring options such as ceramic tile and wooden flooring.

The LVT base layer is formed through a heat and high pressure lamination of PVC crumb and glass skrim. YS9040P PTFE porous sheet is a best release sheet for LVT industry, since Teflon porous fabric is heat resistant, chemical resistant and is porous during PVC melting process.

Performance of PTFE Glass Fiber heavy belt series

★   Smooth surface, excellent release

PTFE coated glass fabrics heavy belt series YS9035AJ, has high PTFE content, which is 62%.

And the surface of YS9035AJ is smooth and shiny.

★   Durability

Fiberglass 7638 coated with high PTFE, which makes this fabric has high tensile strength and good durability.

The property of Teflon coated fiberglass reduce the production cost for customers, and increased the quality of the product.

★   High working temperature.

PTFE coated fiberglass can continuous working from -73°C – +260°C, and the maximum working temperature is +327°C(short term).

★   Chemical resistant

PTFE fiberglass fabric YS9035AJ can resist chemical in plywood, solar cells and so on, apply to drying, vulcanization and other wet and corrosive environment.

Applications of PTFE Fiberglass YS9035AJ

★   Photovoltaic cells production and module lamination

PTFE glass fiber YS9035AJ was used as release sheet in the PV module vacuum lamination process.

The quality of PTFE fabric will be a critical factor for maximum the production uptime, and increasing the quality of module.

PTFE Glass for module lamination and cell welding

★   Lamination of plywood and wood processing

Same as the production of solar cells, PTFE glass cloth is also used as release sheet for lamination of plywood and wood processing.

Due to the high working temperature of lamination, PTFE fiberglass is the perfect solution for release.

Vacuum Bagging Bleeder Cloths, make of PTFE coated fiberglass fabric with low level of PTFE content, which has a higher porosity than normal PTFE coated fabric. This fabric is also named with release fabric & peel ply.

In this case, air and extra resin will be allowed for passing through the bleeder cloths. This fabric is used as release sheet and bleeder cloth, for the manufacturing of aircraft composites, including satcom and weather radomes, helicopter rotor blade, structural components like wings, tail section, fuselage component and so on.

How to use Vacuum bagging bleeder cloths

• Placement: Position the vacuum bagging bleeder cloths above the resin layer, ensuring direct contact with the resin surface.
• Function: The bleeder cloths allow excess resin to escape and facilitate the release of trapped air, ensuring optimal compaction during the curing process.
• Surface Finish: By using the bleeder cloths, you can achieve a smooth and clean surface finish for your composite products.
• Vacuum Setup: Finally, ensure proper vacuum sealing over the bleeder cloths to maintain consistent pressure throughout the curing process.

Vacuum bagging system is consist of vacuum bag, ventilated felt, cover, isolating membrane, bleeder, bleeder cloth(Porous PTFE fabric), composite, PTFE adhesive fabric and molding.

After extracting vacuum, autoclave molding will release high temperature, high pressure by adding heat compression air, for the curing and molding of the composite. And ESONE PTFE coated fabric will provide a easy and clean release after curing process, air, resin and volatile will be allowed for escaping.

The surface of composite will be excellent smooth by using Vacuum bagging bleeder cloths, and composite will be very easy to peeled off from the PTFE peel ply after cured.

Property of PTFE coated Peel Ply

★  Easy release and non stick.

Composite will be easy and clean released from bleeder cloths.

★  Allowing air, resin and volatile escaping during curing

PTFE Peel Ply has a higher porosity than normal PTFE coated fabric, which can allow air, resin and volatile pass through in the curing process.

★  Create super smooth surface for composite

After release, the composite will have a excellent smooth and shiny surface, such as bonnet of automotive.

★  Strong mechanical strength

Vacuum bagging bleeder cloths has high tensile strength, which can resist the high pressure in autoclave. And cloth will not be tore when releasing the peel ply.

In these applications, the release property, mechanical strength and porosity of Vacuum bagging bleeder cloths is critical to the manufacturing process and the quality of the composites.
