Pyrosil™ Tape

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.

Pyrosil™ tapes are sold in 36 ft. rolls only.

Reinforced extra-strength Pyrosil™ also available

We can also supply Pyrosil™ Reinforced Tape. Reinforcement with sinusoidal-shaped glass fiber provides significantly more tensile strength. It also provides resistance to notch sensitivity. Width 1″ (25 mm).
