Silica welding blanket

Product Overview
BSTFLEX Silica Welding Blanket Roll is a woven high-temperature silica fabric supplied in continuous roll form for welding blanket manufacturers, industrial textile converters, distributors and OEM buyers. Available in 70% silica and ≥96% high silica constructions, the material is used for welding blankets, welding curtains, spark barriers and hot-work protection where higher thermal capability than conventional fiberglass is required. Multiple fabric weights, thicknesses and widths are available, with full-roll, cut-to-length and finished welding blanket supply options.

What is a Silica Welding Blanket Roll?
A silica welding blanket roll is woven silica textile supplied as continuous fabric rather than as a pre-sized and sewn welding blanket. The roll format is designed primarily for fabricators, converters, distributors and OEM buyers that manufacture different welding protection products from the same high-temperature material.

Common Conversions / Uses

• Welding blankets
• Welding curtains
• Welding screens
• Spark barriers
• Hot-work protective panels
• Industrial heat barriers
• Equipment protection covers
• Furnace-area protective curtains
• Custom high-temperature fabric assemblies

Silica Grade — Typical Working Temperature — Typical Positioning
70% Silica Fabric | Up to approx. 800°C / 1472°F | Industrial welding and heat protection where extreme 1000°C continuous capability is not required
≥96% High Silica Fabric | Up to approx. 1000°C / 1832°F | More demanding high-temperature welding and thermal protection

1250 g/m² | Approx. 1.30 mm | Approx. 84 cm | ≥96% | Up to approx. 1000°C

Imperial Weights
Finished silica welding blanket constructions include 18 oz and 36 oz options with approx. 0.030 in and 0.060 in thickness references depending on selected material.

Why Choose Silica Instead of Fiberglass Welding Fabric?
Selection Factor | Fiberglass Welding Fabric | Silica Welding Fabric
General Welding Protection | Widely used | Also suitable
Material Cost | Generally lower | Generally higher
High-Temperature Capability | Suitable for many standard welding applications | Selected for higher thermal exposure
Available Constructions | Uncoated and multiple coated options | 70% and ≥96% silica grades plus selected surface treatments
Primary Buying Reason | Economy and general-purpose protection | Higher-temperature welding and thermal protection

Supply Formats
Supply Format | Description | Typical Buyer
Full Roll | Continuous silica welding fabric | Industrial converters, fabricators and distributors
Cut-to-Length Fabric | Continuous material supplied in specified lengths | Fabricators requiring controlled quantities
Cut Panels | Silica fabric cut to specified panel dimensions | Customers performing their own sewing and assembly
Finished Welding Blanket | Sewn and fabricated silica blanket | End users, distributors and OEM finished-product programs

Selection & Specification Notes
- Silica fabric should not be treated as a single material grade; silica content, fabric weight, thickness, yarn construction, weave, surface treatment and usable width all affect performance.
- Higher silica content (≥96%) provides increased continuous temperature capability (~1000°C) but may not be the most cost-effective option when 70% silica (~800°C) is sufficient.
- Temperature rating must consider exposure conditions: continuous vs peak exposures, radiant heat, direct hot-particle contact, welding sparks, spatter, hot slag and installation orientation (vertical vs horizontal).
- Roll width and finished blanket size must be planned: finished blankets may be fabricated from multiple panels if the raw fabric width is insufficient.

Recommended RFQ Items
Provide the following when requesting material specification or quotation: silica grade (70% or ≥96%), operating temperature (continuous and peak), application type (welding, cutting, curtains, screens, equipment protection), fabric weight (g/m² or oz/yd²), thickness, usable width, roll length, quantity (number of rolls or total meters), supply format (full rolls, cut lengths, panels, finished blankets), and any OEM/labeling/packaging requirements.

Additional Notes
- Roll goods normally do not include sewn hems, reinforced edges, grommets, eyelets, attachment straps or finished blanket packaging unless specifically ordered as finished products.
