FSK Tape is a composite tape combining aluminium foil, fiberglass scrim and kraft paper. It adopts acrylic or synthetic rubber-resin adhesive, matched with easy-to-peel silicone release paper. The tape maintains good flexibility to avoid cracking and lifting after pasting, and acts as an effective moisture and vapor barrier.
With stable physical performance, different models cover diverse temperature resistance ranges and adhesion strengths to meet differentiated usage demands. The 3-way FSK backing delivers stronger structural reinforcement, while the 2-way version is cost-effective for conventional sealing work. Solvent acrylic adhesive adapts to extreme high and low temperatures, and solvent synthetic rubber-resin adhesive provides ultra-strong initial tack and bonding force. All tapes have uniform thickness and excellent heat & light reflection capacity, serving as ideal auxiliary materials for thermal insulation and sealing projects.

A: While both are high-strength variations of Reinforced Aluminum Foil Tape, they are designed to match distinct insulation facings. Foil-Scrim-Kraft Tape features a silver metallic finish optimal for sealing foil-faced duct wraps, rigid duct boards, and reflective bubble insulation. ASJ tape, or All Service Jacket Tape, features a heavy-duty white outer layer designed to match white-jacketed pipe insulation networks.
A: Yes. Despite their multi-layer mechanical reinforcement, our tapes apply easily to irregular, curved, or uneven geometric profiles without lifting or peeling.
A: No. The bi-directional or tri-directional fiberglass mesh layer provides outstanding puncture and tear resistance while in service, but when paired with our premium pressure-sensitive adhesive and release liner, it handles cleanly and cuts efficiently on the job site.
A: Our ASJ tape integrates an inner aluminum foil layer that maintains a zero-permeability vapor barrier, keeping moisture away from cold-water piping systems to prevent condensation and pipe sweating.
A: The scrim is a middle layer of bi-directional or tri-directional fiberglass mesh. It acts as a structural backbone, allowing the tape to bend cleanly with the primary insulation facing while providing the high tensile strength required to prevent tearing under pressure.
A: No. Our reinforced tapes are formulated with weather-resistant pressure-sensitive adhesives—such as cold-weather acrylics—ensuring they deliver solid holding power and resist lifting even under severe temperature fluctuations.
