Product Introduction

This high silica self-adhesive tape is manufactured from silica fiber with a purity of 96% or higher, coated with a pressure-sensitive adhesive backing for easy installation. The tape can be applied directly to the surface of the protected object and secured quickly through the pressure-sensitive adhesive properties. The high-temperature resistance allows continuous operation above 1000°C. The pressure-sensitive adhesive decomposes at high temperatures, and the tape can perfectly cover hoses, cables, and pipelines. The tape is suitable for working environments with complex piping systems or difficult disassembly, making it widely used in metallurgy, electric power, coal, and other industries to protect cables and hoses operating under ultra-high temperature conditions.

Core Advantages

Pressure-Sensitive Adhesive Backing

Self-adhesive backing enables quick installation without additional adhesives, clamps, or tie wraps. Press directly onto the protected surface.

1000°C High-Temperature Resistance

Continuous operation above 1000°C. The high silica substrate maintains integrity at extreme temperatures.

Adhesive Decomposes Cleanly

Pressure-sensitive adhesive decomposes at high temperatures without leaving residue or producing toxic fumes, leaving the pure high silica tape in place.

Complex Installation Environments

Ideal for applications with complex piping systems, tight spaces, or where disassembly is not possible. Wrap around existing components without disconnection.

Ultra-High Purity Silica

SiO₂ content ≥96% provides superior thermal stability and chemical resistance at extreme temperatures.

Application Scenarios

Metallurgy industry cable and hose protection

Electric power plant cable wrapping

Coal industry conveyor belt cables

Complex piping system insulation

Hard-to-reach equipment protection

High-temperature cable bundling

Hydraulic hose protection near furnaces

Retrofit installations without disassembly

This high silica self-adhesive tape is suitable for metallurgy industry applications where cables and hoses are exposed to extreme heat from furnaces, molten metal, and hot processing equipment. Electric power plants use the tape for cable protection in boiler areas, turbine compartments, and high-temperature switchgear. The coal industry applies the tape to protect conveyor belt cables, hydraulic lines, and instrumentation wiring in high-temperature zones. Complex piping systems benefit from the tape's ability to wrap around existing components without disconnection. Hard-to-reach equipment areas where traditional sleeves cannot be installed due to space constraints are ideal applications. High-temperature cable bundling in control panels and junction boxes near heat sources uses the tape for thermal protection. Hydraulic hoses near furnaces in steel mills and foundries are protected by wrapping the tape around hoses. Retrofit installations without disassembly are a key advantage, as the tape can be applied to existing systems without shutdown or component removal.

Common Questions and Solutions

Does the adhesive leave residue after high-temperature exposure?

The pressure-sensitive adhesive is formulated to decompose cleanly at temperatures above 400°C. It does not leave sticky residue, char, or ash on the protected surface. The adhesive decomposes into gases that dissipate, leaving the pure high silica tape in place as a protective wrap.

Can the tape be used in applications where the protected surface exceeds 150°C?

Yes. The tape is designed for high-temperature applications. The pressure-sensitive adhesive provides initial positioning and temporary hold at room temperature. Once the operating temperature exceeds 150°C, the adhesive begins to soften and eventually decomposes above 400°C. The high silica tape itself remains fully functional as a thermal barrier. For permanent high-temperature applications, additional mechanical securing is not required as the tape will remain in place by itself once applied around the component.

How should the tape be applied?

Remove the release liner and apply the adhesive side directly to the clean, dry surface of the cable, hose, or pipe. Press firmly to ensure good adhesion. For wrapping applications, overlap each turn by 25-50% of the tape width. The tape can be applied without additional tie wraps for most applications. For high-vibration environments, stainless steel tie wraps can be added for extra security.

Is the tape suitable for use in the coal industry with potential coal dust exposure?

Yes. The high silica tape is non-combustible and does not absorb coal dust into its structure. The smooth surface allows dust to be brushed off. However, ensure that the adhesive side is fully covered (by overlapping or by the underlying surface) to prevent dust from adhering to exposed adhesive. The tape meets coal industry safety requirements for non-flammable materials.

What is the shelf life of the self-adhesive tape?

When stored in a cool, dry place (15-25°C, <50% relative humidity) away from direct sunlight, the tape has a shelf life of 12 months from the date of manufacture. After 12 months, the adhesive tack may decrease. Always store the tape horizontally in its original packaging.

Can the tape be used on irregular surfaces or around fittings?

Yes. The flexible high silica tape conforms to irregular surfaces, elbows, tees, and fittings. For sharp corners or complex shapes, apply the tape in smaller overlapping sections. The adhesive holds the tape in place while you wrap, simplifying installation on vertical or overhead surfaces.

Installation and Handling Considerations

Clean and dry the surface of the cable, hose, or pipe before application. Remove oil, grease, dust, and moisture for optimal adhesive bonding at room temperature.

Store the tape in a cool, dry place at temperatures between 15-25°C. Do not store near heat sources or in direct sunlight. Use within 12 months of manufacture for best adhesive performance.

For applications where the protected component will not exceed 150°C after installation, the adhesive will remain intact. For high-temperature applications (>400°C), the adhesive will decompose and the tape will function as a non-adhesive wrap.

Apply the tape with 25-50% overlap for complete coverage. Start wrapping at the end closest to the heat source. For vertical installations, start at the bottom and wrap upward to prevent water or contaminants from seeping under the overlap.

For applications in the metallurgy, electric power, or coal industries, inspect the tape during scheduled maintenance. The high silica tape does not degrade under normal operating conditions but should be replaced if mechanically damaged.

Wear gloves when handling the tape. The glass fiber edges after cutting can be sharp. The adhesive does not cause skin irritation under normal use but may stick to skin; remove with soap and water.
