Silicone Coated Fiberglass Tape for High Temperature Insulation and Sealing
Product Overview
Silicone coated fiberglass tape is a high-temperature insulation and protection material developed for industrial applications where heat resistance, flexibility, and environmental durability are required. It is manufactured from woven fiberglass fabric coated with silicone rubber, combining the thermal stability and mechanical strength of fiberglass with the surface protection and flexibility provided by silicone.
This tape is commonly used to wrap, insulate, and protect hoses, pipes, cables, and components exposed to elevated temperatures, moisture, vibration, and mechanical contact in industrial environments.
Material Construction
The product consists of two functional layers:
-
Fiberglass base fabric
Provides mechanical strength, dimensional stability, and resistance to elevated temperatures.
-
Silicone rubber coating
Improves surface durability, flexibility, and resistance to moisture, oil splash, and environmental exposure while reducing fiberglass fraying during installation.
This construction allows the tape to perform reliably under repeated wrapping and long-term service conditions.
Typical Applications
Silicone coated fiberglass tape is widely used in:
-
Thermal insulation of hoses, pipes, and tubing
-
Wrapping and protection of electrical wiring and cable assemblies
-
Sealing and insulation in engines, generators, and industrial equipment
-
Protection of joints, flanges, and irregular components
-
Maintenance, repair, and retrofit operations
These applications are commonly found in industrial manufacturing, power generation, automotive, marine, and heavy equipment environments, where continuous heat exposure and environmental stress are present.
Performance Characteristics
-
Designed for continuous exposure to elevated temperatures
-
Silicone surface resists moisture, oil splash, and many industrial fluids
-
Maintains flexibility for wrapping around complex or irregular shapes
-
Non-conductive materials provide electrical insulation properties
-
Suitable for both indoor and outdoor industrial use
Engineering Considerations
Heat Exposure
The fiberglass substrate provides stable thermal performance, while the silicone coating protects the surface from degradation caused by heat and environmental exposure.
Mechanical Handling
Compared to uncoated fiberglass tape, the silicone-coated surface improves abrasion resistance and durability during repeated handling, installation, and maintenance work.
Environmental Resistance
Silicone rubber offers good resistance to UV exposure, moisture, and weathering, supporting long-term use in demanding industrial environments.

Installation & Use
-
Wrap the tape tightly around the component requiring insulation or protection
-
Overlap layers as needed to achieve the desired insulation thickness
-
Secure tape ends mechanically or with compatible fastening methods if required
-
Avoid excessive tension that may distort the fiberglass weave
Limitations
-
Not intended for direct flame exposure without additional fire protection
-
Not designed as a pressure-containing or structural reinforcement material
-
Chemical compatibility should be verified for aggressive fluids or solvents
For applications involving direct flame, molten metal, or extreme heat exposure, additional fire-resistant protection should be considered.
