Weight:
• For applications requiring greater thickness than 425 tape.
• Meets UL 723 specification for class L low flammability.
• Foil backing provides an excellent reflective surface for both heat and light.
• Aluminum foil backing and acrylic adhesive system combine to offer long aging
• The high coefficient of expansion offered by the aluminum allows expansion and
• Performs in a range from -65°F to over 300°F (-54°C to 149°C). Higher
• Store in a clean, dry place at 60-80°F (15-27°C) and 40-50% relative humidity no
