Aluminum foil tape Polax 48 mm x 10 m — heat-resistant sealing and repair tape

Aluminum foil tape Polax 48 mm x 10 m — heat-resistant sealing and repair tape is a foil-backed adhesive tape designed for sealing, patching and thermal insulation tasks. With a 48 mm width and 10 m length, the tape provides a continuous metallic backing that reflects heat, resists moisture and forms airtight seals on HVAC ducts, insulation joints and surface repairs. The foil construction supports mechanical strength and improves longevity in domestic and light-commercial applications where heat resistance and surface protection are required.

Advantages

The foil adhesive layer offers strong adhesion to metal, foil-faced insulation, and many building surfaces while maintaining heat resistance. Its metallic backing provides a reflective surface that reduces radiant heat transfer and helps protect underlying materials from moisture. The tape is easy to cut and apply by hand, conforms well to flat and slightly curved surfaces, and creates a durable, low-profile seal that resists tearing and aging under moderate environmental exposure.

Suitable for

• Sealing joints and seams in HVAC ductwork
• Repairing foil-faced insulation and vapor barriers
• Temporary surface repairs on metal or coated panels
• Reflective heat protection for pipes and ducts
• Moisture protection for seams and overlaps

Key specifications

• Width: 48 mm
• Length: 10 m
• Backing material: aluminum foil
• Adhesive type: pressure-sensitive adhesive for general sealing
• Heat resistance: suitable for moderate-temperature sealing and reflective applications
• Surface finish: metallic reflective

How to use

Ensure surfaces are clean, dry and free from dust, oil and loose particles before application. Measure and cut the required length of tape, peel off the release liner if present, then press the tape firmly onto the target surface, smoothing out air pockets and wrinkles. For best adhesion, apply uniform pressure along the tape length; use a roller or firm hand pressure to create an airtight seal. Overlap adjacent strips by at least 10–15 mm for continuous seams. For curved or irregular surfaces, trim the tape into shorter sections and press each section firmly to conform to the shape.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight. Use at ambient temperatures for surface preparation and application; allow adhesive to age for optimal bond when sealing critical joints. Avoid prolonged exposure to temperatures beyond the product's moderate heat tolerance and avoid continuous immersion in water. For long-term or high-temperature ducting and industrial applications, evaluate the tape's suitability against project-specific temperature and chemical exposure requirements.
