Pyroblanket™ 32 oz and 17 oz
Heat, flame and weld spatter protection, designed to exceed industrial standards where resistance to moisture, sunlight, corona and hydraulic oils is needed.

Pyroblanket™ 32 oz and 17 oz
Our Midweight Pyroblanket™
A midweight (32oz/yd2; 1085g/m2) and lightweight (17 oz/yd2; 578 g/m2) high temperature resistant fabric, constructed from a glass fiber base fabric, impregnated both sides with a specially compounded silicone rubber coating designed to shed heavy weld spatter and resist heat and occasional flame.
Impervious To Contaminants
Pyroblanket™ 32 oz and 17 oz are completely impervious to water, moisture and hydraulic oils. It is used primarily for fabrication of premium grade valve insulation covers, hanging flame-protection blankets in outdoor and offshore use, protective molten splash applications and fabric expansion joints.

Pyroblanket™ 96 oz
Ultra-heavy grade high temperature resistant fabric, designed for use in severe molten splash applications in the primary metals industry.

Pyroblanket™ 96 oz
Tough, Durable And Very Versatile
Our heavyweight – Pyroblanket™ 96 oz (3260 g) /m2) is constructed from a glass fiber base fabric, coated one side only with a very thick layer of specially compounded silicone rubber that sheds molten splash almost instantly, before heat transfer can occur.
It is used primarily for fabrication of specialized covers and curtains in applications such as electric arc furnace (EAF), blast furnace and casting, where severe molten splash occurs. It can be cut and sewn into custom shapes and formats, or used with other Insulflex high temperature fabrics to create unique protection products for the most severe industrial applications.
Withstands Contaminants, High Heat And Flame
The silicone rubber coating is completely impervious to water, moisture and hydraulic oils. When exposed to high temperatures or molten splash for extended periods, the coating transforms into a silica refractory crust.
