Core Value
The 220V High Temp Fiberglass Reinforced Silicone Rubber Heater is a highly versatile, surface-conforming surface heating solution engineered for rapid mounting and removal on cylindrical, spherical, or irregular metal surfaces. Built with high-tensile fiberglass fabric embedded between layers of premium silicone rubber, this heater combines mechanical tear resistance with extreme flexibility and high electrical insulation strength.
Featuring integrated high-temperature industrial Velcro (hook-and-loop) fasteners, the element wraps snugly around target components—such as gas cylinders, process pipelines, valves, pumps, and drums—ensuring intimate surface contact without requiring pressure-sensitive adhesives or complex mechanical metal clamps. High-purity nickel-chromium (Ni80Cr20) resistance alloy wire or precision-etched foil circuits ensure uniform heat transfer across the entire surface. Designed for continuous operating temperatures up to 200°C (with peak limits up to 230°C), every heater is engineered for moisture resistance, chemical durability, and long operational life under repeated thermal cycling.
- ✓ Tool-Free Velcro Installation: High-temp hook-and-loop straps allow rapid wrap-around installation, adjustment, and frequent removal for maintenance inspection.
- ✓ Fiberglass Fabric Reinforced: High-tensile fiberglass mesh substrate prevents tearing, stretching, and mechanical puncture under industrial handling.
- ✓ Uniform Thermal Profile: Etched foil or resistance wire element layout delivers even watt density, eliminating localized cold zones on curved vessels.
- ✓ High Temperature Capability: Continuous operation at 200°C (392°F), with short-term exposure resistance up to 230°C (446°F).
- ✓ Moisture & Chemical Resistant: Silicone outer sheath protects heating circuits against moisture, weather, mild acids, industrial oils, and chemical splatter.
- ✓ Flexible & Conforming: Easily wraps around small-diameter piping (down to 25mm radius) or large industrial storage tanks.
- ✓ Integrated Temperature Control Options: Compatible with digital temperature controllers, inline thermal fuses, PT100 sensors, or K/J thermocouples.
- ✓ Quality Assured: 100% tested for dielectric withstand voltage (1500V/1min), insulation resistance, and dimensional accuracy prior to dispatch.

Installation & Handling Guidelines
- Surface Preparation: Clean the target pipe, tank, or cylinder surface to remove grease, rust, or loose rust scale for optimal thermal contact.
- Wrapping & Positioning: Wrap the silicone heater snugly around the target vessel, ensuring the heating surface sits flat against the metal wall without folds, overlap, or air pockets.
- Velcro Tensioning: Pull the Velcro straps tight to lock the heater in place. Ensure equal tension across all straps so the element maintains firm contact throughout thermal expansion.
- Electrical Wiring: Connect power leads to the rated supply voltage printed on the product label. Never connect a low-voltage element directly to grid voltage.
- Temperature Control: Use an external digital thermostat or integrated temperature sensor (e.g., PT100/Thermocouple) to prevent exceeding the max continuous temperature limit of 200°C.
- Storage & Maintenance: When removing, allow the heater to cool completely. Store flat or loosely rolled; do not tightly fold or crease the heater, as sharp bends can break internal resistance wires.
