Why do inferior silicone fiberglass fire-resistant fabrics on the market crack, delaminate, or break down within 6 months?

Low-grade alternatives come with false temperature resistance ratings, are prone to silicone coating peeling, and glass filament shedding. Many carry unverified Class A2 fire certificates, alongside weak resistance to oil, acid, and outdoor weather, plus rough, defective surface finishing.

These substandard materials require full replacement every 3–6 months, resulting in costly project downtime, extra rework and failed fire safety inspections.

Premium Suntex HTV Silicone Fabric Core Specifications

Our fabric is constructed with a high-tensile fiberglass substrate and virgin silicone rubber via high-temperature vulcanization (HTV), certified to GB 8624-2006 Class A2 fire performance.

Operating temperature range: -50 °C to 550 °C

Features:

  • Fireproof, oil-repellent, waterproof, and anti-aging;
  • Easy to cut and sew, with a full range of thicknesses and color customizations available.

4-Step On-Site Quality Inspection Checklist

  • Surface Check: Uniform, dense silicone coating with zero pinholes
  • Hand Feel Test: Soft, elastic texture, no rigid hardening
  • Adhesion Test: No coating rubbing off or delamination after repeated bending
  • Base Cloth Check: Complete intact fiberglass weave with evenly distributed coating

Important Reminders

  • Low-cost, unqualified fabrics incur hidden recurring maintenance and rework costs over time.
  • Application Limitation: This material is not recommended for use in working environments with sulfur dioxide (SO₂) in flue gas.

Opt for Suntex high-temperature vulcanized silicone fabric: zero cracking and delamination, fully certified, fully customizable, to drastically reduce your long-term project operating costs.
