Alu. Foil Tape (FR Grade Class O & UL 723 ASTM E84 Fire Rating)

A nominal 40 micron (1.6 mil) high tensile strength aluminum foil backing, combined with a high performance flame retardant solvent acrylic adhesive, protected by an easy-release silicone release paper.

FEATURES

Aluminum backing provides excellent reflection of both heat and light. High quality adhesive with super strong adhesion and holding power offers reliable and durable Foil-Scrim-Kraft Facing joints and seams sealing in HVAC ductwork application. Low moisture vapor transmission rate makes BondTape AF4025R an excellent vapor barrier. Service Temperature range from -30° to +120°C (-22° to +248°F).

TYPICAL APPLICATIONS

HVAC industry for joining and sealing Foil-Scrim-Kraft Facing laminated fiberglass blanket / duct board joints and seams; joining and sealing flexible air duct seams and connections. May also be used for other industrial uses requiring a tape with these characteristics and benefits.
