PTFE Mold Release Tape, make of woven fiberglass coated with high quality PTFE(TEFLON), and back side coated with Silicone PSA. This mold release tape has higher tensile strength than normal self adhesive PTFE fabric. In this case, ESONE adhesive tape will be easily took down after repeatedly used.

ESONE mold release adhesive fabric is used to stick the molding, for the manufacturing of aircraft composites, wind power blade composite, like satcom and weather radomes, helicopter rotor blade, structural components like wings, tail section, fuselage component and so on.

Porous Teflon Sheet

Vacuum bagging system is consist of vacuum bag, ventilated felt, cover, isolating membrane, bleeder, bleeder cloth(Porous PTFE fabric), composite, PTFE Mold Release Tape(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 PTFE Mold Release Tape and Vacuum bagging bleeder cloths, and composite will be very easy to peeled off from the PTFE peel ply after cured.

Property of PTFE Release Film

★  Easy release and non stick.

Composite will be easy and clean released from bleeder cloths.

★  Create super smooth surface for composite

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

★  Strong mechanical strength

PTFE Mold Release Tape has high tensile strength, which can resist the several cycles of high pressure in vacuum bagging and is reusable, due to adhesive tape will not be tore when releasing from molding.

1) Helicopter blade

ESONE is selling PTFE mold release film and bleeder cloth to Helicopter blade industry, which has high request of the mechanical strength, in order for reuse mold release tape many times.

2) Airplane composite manufacturing

ESONE PTFE coated fabric is used in composite mold protection and release liners, vacuum bagging bleeder cloths, which result in a excellent smooth and shiny surface of the airplane composite, like fuselage components, wings, tail and so on.

3) satcom and weather radomes

Satcom and weather radomes are made of resin reinforced fiberglass composite, which will use vacuum bagging system for composition.

4) Wind power blade composite

Molding for wind power blade is very large and long, if PTFE mold release fabric or bleeder cloth got any problem, then all the molding will be influenced. In this case, this industry has high request of the quality of PTFE coated fabric.

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.

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.
