1BSTFLEX Silica Welding Blanket Roll is a high-temperature woven silica fabric supplied in continuous roll form for welding blanket manufacturers, industrial textile converters, welding safety distributors and OEM purchasing programs.
Compared with conventional fiberglass welding fabric, silica textile is selected for applications requiring greater thermal capability. BSTFLEX supplies both 70% silica fabric and ≥96% high silica fabric, allowing buyers to select the appropriate construction according to operating temperature, fabric weight, thickness, welding exposure and purchasing budget.
The material can be supplied as roll goods for local cutting and fabrication, as cut-to-length material, or converted by BSTFLEX into finished welding blankets.
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.
Depending on the selected grade, silica roll material can be converted into:
Silica fabric should not be treated as one single material grade.
BSTFLEX currently supplies two important silica groups for industrial thermal protection:
| Silica Grade | Typical Working Temperature | Typical Positioning |
|---|---|---|
| 70% Silica Fabric | Up to approximately 800°C / 1472°F | Industrial welding and heat protection where extreme 1000°C continuous capability is not required |
| ≥96% High Silica Fabric | Up to approximately 1000°C / 1832°F continuous exposure | More demanding high-temperature welding and thermal protection |
The higher silica content should not automatically be selected for every project. If the operating conditions are within the capability of a 70% silica construction, it may provide a practical balance between thermal performance and material cost.
Where sustained thermal exposure is more severe, ≥96% high silica fabric should be evaluated.
BSTFLEX 70% woven silica fabric is available in several constructions suitable for welding blankets, curtains and industrial heat barriers.
| Fabric Weight | Nominal Thickness | Available Width | Silica Content | Working Temperature |
|---|---|---|---|---|
| 600 g/m² | Approx. 0.75 mm | Approx. 92 / 100 cm | 70% ±5% | Up to approximately 800°C |
| 880 g/m² | Approx. 1.00 mm | Approx. 92 / 100 cm | 70% ±5% | Up to approximately 800°C |
| 1100 g/m² | Approx. 1.30 mm | Approx. 92 / 100 cm | 70% ±5% | Up to approximately 800°C |
Available width and roll configuration should be confirmed against the exact fabric construction and production order.
For more severe high-temperature applications, BSTFLEX supplies woven silica fabric manufactured with ≥96% silica content.
Current high silica fabric constructions include several weights and thicknesses. The following are representative options particularly relevant to welding and thermal protection fabrication:
| Fabric Weight | Nominal Thickness | Typical Width | Silica Content | Working Temperature |
|---|---|---|---|---|
| 600 g/m² | Approx. 0.70 mm | Approx. 92 / 100 cm | ≥96% | Up to approximately 1000°C |
| 880 g/m² | Approx. 1.00 mm | Approx. 92 cm | ≥96% | Up to approximately 1000°C |
| 1150 g/m² | Approx. 1.30 mm | Approx. 92 / 100 cm | ≥96% | Up to approximately 1000°C |
| 1250 g/m² | Approx. 1.30 mm | Approx. 84 cm | ≥96% | Up to approximately 1000°C |
BSTFLEX also manufactures other high silica fabric weights and thicknesses. The exact construction should be selected according to the required welding protection performance rather than simply choosing the heaviest available material.
Silica welding blankets are also commonly specified in imperial fabric weights.
Existing BSTFLEX finished silica welding blanket constructions include 18 oz and 36 oz silica cloth options, with approximately 0.030 in and 0.060 in thickness references depending on the selected material.
When purchasing roll material, however, buyers should confirm the exact silica grade, metric fabric weight, thickness and usable width rather than relying on the oz/yd² description alone.
Not every silica grade, weight and thickness combination should be assumed to be interchangeable.
Fiberglass is widely used for economical general welding protection. Silica is selected when the thermal requirement moves beyond the practical range of conventional fiberglass constructions.
| 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 |
The decision should still consider sparks, spatter, slag exposure, installation position and contact duration rather than temperature alone.
The words "silica fabric" do not define the complete material.
A professional specification should identify the actual silica content.
BSTFLEX offers both 70% silica and ≥96% silica constructions because the two materials serve different cost and performance requirements.
A buyer requesting only "silica welding blanket roll" should therefore provide the operating conditions so the silica grade can be selected correctly.
Silica percentage is only one part of the specification.
Two rolls manufactured with similar silica content can still behave differently because of:
For welding blanket fabrication, heavier material may provide greater physical mass and thermal separation, but fabric weight alone does not prove suitability for every slag or molten-material exposure.
A maximum temperature number is not enough to specify a silica welding blanket roll.
Buyers should distinguish between:
A fabric hanging vertically beside a welding operation can experience a different thermal load from the same material placed horizontally below cutting work where hot particles remain on the surface.
For severe exposure, provide the actual welding or cutting process rather than purchasing only by a nominal temperature number.
Roll goods allow industrial fabricators to produce different finished dimensions from the same silica fabric.
The material can be converted into:
Finished dimensions such as 6 × 6 ft, 6 × 8 ft, 8 × 8 ft or 10 × 10 ft are only examples. Other dimensions can be fabricated according to the actual project and available material width.
Silica fabric roll width is an important consideration when planning large finished welding blankets.
The finished blanket may be wider than the usable width of the base fabric. In that case, several fabric panels can be joined during fabrication according to the required finished construction.
Buyers should therefore distinguish between:
A large finished blanket should not automatically be interpreted as one seamless piece of fabric.
Industrial converters should calculate material requirements from usable roll width rather than finished blanket area alone.
Consider:
For repetitive OEM production, providing BSTFLEX with the finished product drawing can help evaluate a practical fabric construction and supply format.
| 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 |
For customers requiring completed products instead of roll goods, BSTFLEX also supplies Silica Fabric Welding Blankets.
Welding safety distributors can use silica roll material to serve local fabrication customers while offering finished blankets to customers requiring ready-to-use products.
This creates a broader product program consisting of:
Distributors can therefore cover both raw-material and finished-product purchasing requirements from the same material family.
For repeat OEM programs, the material specification should be controlled more closely than for one-time general maintenance work.
The approved purchasing specification can include:
Once a material has been approved, subsequent production should follow the agreed specification rather than substituting another silica grade solely because the general product name is similar.
Not every industrial welding application requires ≥96% silica.
Where the working environment remains within the confirmed range of 70% silica fabric, this grade can provide an effective high-temperature textile while avoiding unnecessary material cost.
The current BSTFLEX 70% Woven Silica Fabric range provides several fabric weights for welding blankets, curtains and industrial heat barriers.
Where continuous thermal exposure is more demanding, ≥96% high silica fabric should be evaluated.
BSTFLEX 96% High Temp Silica Fabric is manufactured for continuous high-temperature industrial applications and is available in multiple fabric weights and thicknesses.
For welding blanket production, select the exact fabric according to the required combination of thermal capability, thickness, handling and final blanket construction.
A silica welding blanket roll normally does not include finished blanket fabrication features unless specifically ordered.
Standard roll goods should not automatically be assumed to include:
These features are specified when the raw silica fabric is converted into a finished welding blanket.
BSTFLEX supports custom silica roll requirements for industrial distributors, fabricators and OEM buyers.
Depending on the selected grade, customization can include:
The available combination must be confirmed against the selected silica fabric and production quantity.
Heat-cleaned fiberglass remains an economical solution for many general welding applications.
Silica should be selected when the application requires greater high-temperature capability rather than simply because silica is considered a premium material.
For standard general-purpose requirements, compare the Heat Cleaned Fiberglass Welding Blanket Roll.
For high-temperature applications, silica can provide a more appropriate thermal platform.
Acrylic and silicone coated fiberglass rolls solve different problems from silica fabric.
Coated fiberglass is often selected for surface durability, abrasion resistance, moisture resistance or repeated handling.
Silica is selected primarily when higher-temperature capability is the main material requirement.
For lower-temperature applications where coating properties are important, compare the Acrylic Coated Fiberglass Welding Blanket Roll and other coated welding fabrics.

It is woven silica fabric supplied in continuous roll form for subsequent cutting and fabrication into welding blankets, curtains, screens and other industrial high-temperature protection products.
The primary difference is silica content and corresponding thermal capability. BSTFLEX 70% silica fabric is specified for working temperatures up to approximately 800°C, while the current ≥96% high silica fabric is designed for continuous exposure up to approximately 1000°C.
No. The correct grade depends on operating temperature, application, mechanical requirements and cost. Using ≥96% silica where 70% material already satisfies the application may add unnecessary material cost.
BSTFLEX supplies multiple silica fabric weights. Current 70% constructions include 600, 880 and 1100 g/m². The ≥96% high silica range includes several additional weights and thicknesses. Confirm the required welding application so the appropriate construction can be selected.
Yes. Continuous roll supply is intended for converters, welding blanket manufacturers, distributors and OEM buyers.
Special roll lengths and packaging can be evaluated according to the selected silica fabric and order quantity.
Yes. BSTFLEX can supply roll material or manufacture finished silica welding blankets according to customer dimensions and fabrication requirements.
Normally no. Grommets, hems, sewing and reinforcement belong to the finished welding blanket specification rather than standard roll goods.
Material suitability should be confirmed against the actual welding or cutting process, particle size, contact duration, installation position and required protection level. A high silica percentage or temperature figure alone should not be treated as proof of suitability for every molten-material exposure.
Send BSTFLEX the required silica grade, fabric weight, thickness, usable width, roll length, quantity and intended welding or hot-work application.
If the material has not yet been selected, provide the continuous operating temperature, maximum short-duration exposure, welding or cutting process, expected sparks or spatter and the type of finished product you plan to manufacture.
For OEM fabrication programs, finished-product drawings and common blanket dimensions can also help determine suitable roll width, fabric construction and material requirements.
BSTFLEX can supply full rolls, cut-to-length silica fabric, cut panels and finished welding blankets for industrial distributors, fabricators and OEM buyers.
