Linered Aluminium Foil Tape
FL1702 is a linered aluminium foil tape with a high tensile strength aluminium foil carrier and pressure sensitive acrylic adhesive. It’s designed for sealing foil-faced insulation, pipe insulation sections and metal ducting, with strong adhesion and UL723 and BS476 Class O fire rated performance.
FL1702 Linered Aluminium Foil Tape provides a reliable sealing solution for insulation, HVAC and ducting applications. It combines a high tensile strength aluminium foil carrier with a pressure sensitive acrylic adhesive to create a durable bond in demanding environments.
The tape is designed for sealing foil-faced insulation materials, pipe insulation sections and metal ducting. It helps maintain thermal efficiency and reduces moisture vapour ingress through joints and seams, supporting the long-term performance of insulation systems in commercial and industrial settings.
FL1702 offers strong adhesion to steel at 15N/25mm and a tensile strength of 45N/25mm. The acrylic adhesive performs reliably across a wide temperature range, making the tape suitable for both indoor and outdoor use.
The 40 micron aluminium foil backing reflects heat effectively and provides a robust barrier against moisture vapour, while the siliconised paper release liner allows clean, controlled application.
FL1702 meets UL723 Fire Rating 25/50 requirements and achieves Class O certification to BS476 Parts 6 and 7, making it well suited to HVAC, insulation and building service applications where fire performance is important.

Instructions
Ensure all surfaces are clean, dry and free from grease, dust and loose material before application.
Remove the release liner and apply the tape with firm, even pressure across the joint or seam.
For best results, apply the tape between +10°C and +40°C.
Press firmly along the entire length of the tape to achieve maximum adhesion and sealing performance.
Store the tape in a clean, dry environment and keep it away from excessive heat and direct sunlight.
