0.45mm PU Coated Fiberglass Fabric Cloth For Welding Spatter Sparks Protection

PU(Polyurethane) coated fiber glass fabric is a woven fiberglass cloth substrate which has been coated on one side or both two sides with a specially compounded grey polyurethane coating. Mass per unit of this PU coated glass fabric is 460g/m2. Base cloth is satin(cross twill) weave 3732 fabric. It is 430g/m2 and 0.43mm thick. When coated with 15g/m2 grey PU coating each side, totally weight per unit can be 460gsm, and thickness will be 0.45mm.

One special property of PU coated fiberglass cloth is, usually common coated fiberglass fabric like silicone or PTFE coated fabric should be used below 260℃. While PU coating is able to resisting instantaneous temperature up to 1100 degree Celsius. So it is very suitable materials for welding sparks/spatter shield, good for fire/welding blanket/curtain. Coated fiberglass fabric also have some special properties like chemical corrosion resistance, electrical insulation, high strength, no itchy, rich colors.

Properties:

1. 15g/m2 PU coating on both sides
2. Pu coating can bear 1100℃ instantaneously
3. Resist most acids, Chemical corrosion resistance
4. Waterproofing (it is washable)
5. Heat resistant, resist high temperature below 260℃

Application:

• Welding Spatter Shield
• Fire Curtain, Fire Doors
• Fabric Air Distribution Ducts
• Ductwork Connector
• Thermal Insulation Jacket/Exhaust Blanket
• Fire/Smoke Control Systems

Fiberglass are also available in blended and coated choices. Blended fibers fabric are manufactured from a mixture of two or more different kinds of fibers. However coated fiberglass products can be improved or sized glass fibers. There are silicone/pvc/PFTE/pu coatings that offers different special needs.

Data Sheet Of Base Cloth 3732:

Satin Weave:

The eight harness satin is similar to the four harness satin except that one filling yarn floats over seven warp yarns and under one. This is a very pliable weave and is used for forming over curved surfaces.

3732 fiberglass fabric is a widely used basic cloth for coating. It is always used for fire blanket because of its suitbale thickness. When coatded with PU coating, because PU coating can resist 1100℃ for a short time, this PU coated 3732 fabric is very suitable for fire blanket and welding blanket for fire, welding sparks/spatters protection.
