Key features

Formulated with premium synthetic butyl rubber to provide an exceptional zero-leakage seal, ensuring stable and consistent vacuum pressure throughout long resin infusion and curing cycles.

Maintains its strong tack and dimensional stability during room temperature or elevated oven curing processes without softening, melting, or degrading.

Engineered to peel off effortlessly from both composite bags and expensive metal/composite molds after high-temperature curing, drastically saving tool cleanup time and labor costs.

Exhibits powerful immediate adhesion to all common tooling substrates, including aluminum, steel, fiberglass, and carbon fiber molds, requiring minimal finger pressure to secure.

The highly flexible and clay-like compound effortlessly conforms to sharp corners, deep recesses, and complex pleats, completely eliminating vacuum bridging issues.

A versatile workshop consumable widely utilized in wind energy blade manufacturing, marine yacht hulls, automotive carbon fiber parts, and aerospace composite structures.

If minor punctures occur during vacuum setup, the self-healing butyl rubber properties allow it to reseal itself with simple finger smoothing, preventing critical part loss.

Contains zero solvents or hazardous VOCs, ensuring a safe working environment for technicians; it remains stable without drying out or losing tack under standard storage.

Each roll features a perfectly centered, tough backing liner that protects the tape from contamination and tears off cleanly on the shop floor without tearing or sticking.

We support flexible private labeling, specific roll widths (e.g., 12mm), customized lengths, and heavy-duty, moisture-proof box packaging tailored for global shipping.

Product Q&A

Q:Q1: Will this sealant tape leave any glue residue on expensive molds after high-temperature curing?

A: No, our tape is formulated with high-grade synthetic butyl rubber designed specifically for advanced composites. It maintains excellent dimensional stability during heated cycles and offers a clean, effortless release from both metal (aluminum/steel) and composite molds after curing, leaving zero sticky residue behind.

Q:Q2: How do I ensure a 100% airtight seal and prevent vacuum leaks when applying the tape?

A: For the best seal, ensure the mold surface is completely free of dust, grease, or excess loose release agents before application. Apply the tape firmly onto the tooling surface using steady finger pressure, overlapping the ends cleanly at the corners. For complex or sharp contours, leave a small pleat or "dog-ear" in the vacuum bag to prevent bridging and tension-induced leaks.

Q:Q3: What is the maximum temperature limit, and can it be used in autoclave processes?

A: We offer a versatile range of vacuum sealant tapes tailored to different workshop curing requirements:
