Silicone rubber high temperature tape forms a non-adhesive, self-bonding, self-curing, liquid-tight insulation barrier
High Temperature Insulation Tape
Pyrosil™ is a non-adhesive, iron oxide red silicone rubber tape, designed to withstand continuous exposure to temperatures up to 475°F (246°C).
Broad application range
By virtue of its high dielectric strength, Pyrosil™ heat resistant tape is an excellent alternative to heat shrinkable tubing, vinyl tapes and wraps.
Typical applications include: wrapping wiring harnesses; protecting splices and terminations of power cables; insulating coils on motors and generators.
Pyrosil™ is also ideal for use as an end sealant in conjunction with Pyrojacket® to prevent hydraulic oils and contaminants wicking into the inner braid.
Reinforced extra-strength Pyrosil™ Tape also available
Reinforced with sinusoidal-shaped glass fiber to provide higher tensile strength and resistance to notch sensitivity. Width 1” (25 mm).
