VEXTRA® (GLV) Tadpole

AMI’s VEXTRA® (GLV) is a high heat resistant tadpole tape that is ideal for gasketing applications found in lab ovens, industrial boilers and furnaces. It can be manufactured so that it conforms to various channel sizes. The tape is engineered with a vermiculite coating and remains stable up to 1500°F. The vermiculite coatings is inorganic, chemically inert, noncombustible and orderless. VEXTRA GLV tape is also available with a high performance pressure sensitive adhesive. The adhesive limits the temperature resistance to 300°F, however the adhesive is generally used to aid in the installation process and after the tape is in place, it is mechanically bonded so that the adhesive is no longer necessary. Thickness: .060″ wall

Data Sheet

VEXTRACombat heat with superior vermiculite armor.

Used for Welding Protection, Furnace Curtains, Pipe Wrapping/Lagging, Expansion Joints, Heat Shield/Containment, Machinery Protection, Removable Flange/Valve Covers, Stress Relief, Exhaust Manifold Wrap and more.

  • Remains stable to 1500°F (815°C) (Upper Temperature Limit)
  • Continuous operating temperature 1000°F (540°C)
  • Non-combustible vermiculite-coated fiberglass
  • 50% More protection than fiberglass
  • Improved abrasion resistance
  • Coating acts as armor to the fiberglass, providing better resistance to direct flame
  • Heat travels across the fabric—not through it
  • Available in three colors – blue, black and bronze

VEXTRA® Textiles are 100% fiberglass coated with a golden vermiculite solution made of plate-like mineral crystals. This non-combustible coating acts like armor when heat strikes the fabric, causing the heat to travel across the fabric rather than through it, shielding the fiberglass from the heat source.
