High Performance Polyester Tape for Autoclave and Composite Bonding, Clean Release After High Temperature Cycles

The reinforced high-modulus PET backing maintains structural integrity under combined high heat (up to 177°C) and vacuum pressure inside autoclaves, preventing tape rupture, creep or resin bleed during composite curing. The proprietary adhesive system achieves balanced tack: strong enough to fix vacuum bag films, release cloth and mold edges during molding, yet peels off fully clean once the composite cools, leaving no adhesive traces that ruin fiber surface finish or block secondary bonding.

Professional-Grade Advantages

1. Autoclave Cycle Tolerance: Stable performance under multiple 177°C pressurized heating cycles, suitable for long-duration composite curing over 4 hours.

2. Resin & Chemical Resistance: Impermeable to epoxy, polyester and vinyl ester composite resins, no adhesive swelling or dissolution.

3. Non-Contamination Formula: Free of silicone and heavy metal additives, complies with aerospace composite raw material standards.

4. High Conformability: Moderate elongation adapts to curved mold surfaces without gap generation during vacuum bagging.

5. Easy Post-Process Handling: Can be peeled off warm composite parts without fragmenting, reducing manual cleaning time greatly.
