Fiberglass fabric welding blanket

Overview
BSTFLEX heat-cleaned fiberglass welding blanket roll is an uncoated woven fiberglass supplied in continuous rolls for fabrication of welding blankets, welding curtains, spark barriers and industrial hot-work protection. It is intended for distributors, converters, fabricators and OEM buyers requiring flexible fiberglass fabric for local cutting and sewing. Custom roll widths, cut lengths and finished blankets are available to meet project requirements.

Supply & Order
MOQ: 1 roll. Supply forms: continuous roll, cut-to-length, or fabricated blanket.

What is a heat-cleaned fiberglass welding blanket roll?
A heat-cleaned fiberglass welding blanket roll is a woven fiberglass fabric delivered as a continuous roll rather than a pre-sewn blanket. The fabric is heat treated to reduce organic processing residues while maintaining the woven structure. As an uncoated material it is suitable for subsequent cutting, sewing and conversion into finished protective items.

Heat-cleaned vs uncoated fiberglass welding blanket roll
The terms heat-cleaned and uncoated are often used for related purchasing needs. Buyers should specify construction details (heat treatment, weight, weave, finish) rather than relying on terminology alone. Coated constructions (acrylic or silicone) provide different handling and durability characteristics.

Key specification summary
Base material: woven fiberglass fabric
Surface: heat-cleaned, uncoated
Polymer coating: none
Supply form: continuous roll, cut length or fabricated blanket
Color: white or tan depending on construction
Primary use: welding protection, spark barriers and hot-work fabric conversion
