Fiberglass welding blanket

Product Overview
BSTFLEX Vermiculite Coated Fiberglass Welding Blanket Roll is a mineral‑treated fiberglass fabric supplied in continuous rolls for welding blanket manufacturers, industrial textile converters, distributors and OEM buyers. The vermiculite coating improves the heat and abrasion performance of the fiberglass surface, making the material suitable for welding blankets, curtains, spark barriers and demanding hot‑work protection. Available constructions range from approximately 0.8 mm to 3.0 mm thickness, with multiple fabric weights and custom fabrication options.

Key Benefits

• Improved resistance to direct heat
• Improved resistance to sparks
• Improved surface abrasion resistance
• Better protection of the fiberglass yarn surface
• Improved performance in demanding welding environments
• Good flexibility for cutting and sewing
• A dry mineral‑treated surface without silicone rubber coating

Typical Applications

• Welding blankets
• Welding curtains
• Spark and spatter barriers
• Temporary hot‑work barriers and screens
• Fabrication shops and metalworking facilities
• Maintenance welding, shipyard hot work and industrial repair operations
• Grinding and cutting protection

Buying and Fabrication Notes

• Roll goods are raw fabrication material and do not automatically include grommets, eyelets, sewn hems, reinforced edges, attachment straps or individual finished-product packaging unless specified.
• Standard roll width is approx. 100 cm / 40 in; larger finished blankets may require joined panels.
• Final specification should always be confirmed against the exact fabric construction ordered.
