High Silica Welding Blanket

Product Overview

LXHTR High Silica Welding Blankets are manufactured from high-silica fiber fabrics containing over 96% SiO₂, providing excellent protection against welding sparks, molten metal splash, radiant heat and high-temperature exposure.

Compared with conventional fiberglass welding blankets, high silica welding blankets offer significantly higher temperature resistance and improved performance in steel mills, foundries, shipyards, power plants and heavy industrial environments.

Available in multiple fabric weights, coatings and customized dimensions, these blankets can be used as welding protection covers, thermal barriers, equipment shielding blankets and removable heat protection systems.

Core Design Features

• High Silica Fiber Construction — Made from high-silica fabrics containing over 96% SiO₂ for superior thermal resistance.
• Extreme Heat Protection — Provides continuous protection at temperatures up to 1000°C.
• Molten Metal Splash Resistance — Designed to withstand sparks, slag and molten metal splash generated during welding and cutting operations.
• Multiple Surface Treatments — Available in untreated, vermiculite-coated and silicone-coated versions for different applications.

Key Advantages

• Reliable Spark Protection — Helps protect equipment, floors and nearby work areas from welding sparks and hot debris.
• Heat Resistant Performance — Suitable for high temperature applications including welding, cutting, grinding and maintenance work.
• Reduced Fiber Irritation — Coated versions help minimize airborne fibers and improve handling comfort during operation.
• Industrial Durability — Heavy duty construction supports long service life in industrial environments.
• Custom Manufacturing Available — Custom dimensions, thicknesses and finishing options are available for different project requirements.

FAQ

What is the difference between a high silica welding blanket and a fiberglass welding blanket?

High silica welding blankets provide significantly higher temperature resistance (up to 1000°C continuous) and better molten metal splash protection than standard fiberglass welding blankets.

Can the blanket withstand molten metal splash?

Yes. This welding blanket offers excellent resistance to welding slag and molten metal splash, making it suitable for foundries and steel plants.

Is silicone coating recommended for high-temperature applications?

Silicone coating improves abrasion and water resistance, but the coating itself is typically limited to approximately 260°C. For direct exposure to extreme temperatures, uncoated or vermiculite-coated high silica blankets are generally recommended.

Can custom sizes be manufactured?

Yes. Custom dimensions, edge treatments, grommets and coatings are available.

Which coating is best for welding applications?

Vermiculite coating is generally preferred for high-temperature welding and molten splash protection, while silicone coating is more suitable when additional abrasion and moisture resistance are required.
