Describe the actual heat exposure
State whether the fabric sees warm air, radiant heat, intermittent sparks or direct hot particles. Include contact duration and whether the fabric is exposed to molten slag. Do not use a continuous working-temperature number as a substitute for an application assessment.
- State process, orientation and distance from the heat source.
- Identify spark, spatter, abrasion, oil, moisture and cleaning exposure.
- For slag exposure, request a sample evaluation under the agreed method and confirm the finished assembly.
Specify the coating and fabric together
The substrate, PU formulation, coating sides, finished weight, thickness and color define the offered construction. Similar product names can describe different builds.
- Record base fabric weave and weight.
- Choose one- or two-sided coating based on exposed surfaces and fabrication.
- Confirm width, roll length, color and accepted tolerances.
Use test evidence that matches the project
Ask for the exact standard, edition, method and report scope required by the customer. Evidence for one material or sample does not automatically cover a different finish or fabricated product.
Frequently asked questions
Is PU-coated fabric automatically suitable for welding slag?
No. Determine the full exposure, including spatter type and duration, and validate the proposed construction to the agreed evaluation method.
Do PU-coated fiberglass fabrics have one universal temperature rating?
No. The applicable limit depends on the exact construction and test conditions. Use approved product data for the proposed material.
