Basalt woven tape has become a preferred high-temperature insulation material for engineers and manufacturers seeking durability, stability, and fire resistance in demanding environments. Made from continuous basalt fibers derived from natural volcanic rock, this material offers a combination of mechanical strength and thermal endurance that exceeds traditional fiberglass products. This technical guide provides a detailed overview of the specifications, performance characteristics, and key benefits of basalt woven tape to support engineering decisions and application planning.

What Is Basalt Woven Tape

Basalt woven tape is produced by melting natural basalt rock and extruding it into continuous filaments, which are then woven into a narrow, strong, and heat-resistant textile structure. The material retains the natural mineral composition of basalt, giving it excellent high-temperature performance and a stable fiber structure.

Core technical characteristics include

• Continuous operating temperature up to 700°C

• Short-term exposure capability up to 850°C

• High tensile strength with minimal shrinkage

• Resistance to abrasion, vibration, and corrosion

• Non-combustible and environmentally friendly fiber composition

These qualities make basalt woven tape suitable for high-heat insulation and protective wrapping across multiple industries.

Technical Specifications of Basalt Woven Tape

Although specifications can vary by manufacturer, basalt woven tape generally offers the following standard technical ranges.

Typical dimensions

• Width options from 10mm to 100mm or customized based on project needs

• Thickness commonly between 1.5mm and 3mm

• Roll lengths from 30 meters to 50 meters depending on width and density

Temperature ratings

• Continuous resistance: 700°C

• Peak short-term resistance: 850°C

• Melting point near 1450°C

Mechanical performance

• High tensile strength suitable for wrapping under tension

• Excellent vibration resistance, suitable for engine and exhaust systems

• Low thermal conductivity, providing efficient heat insulation

Chemical and environmental resistance

• Resistant to fuels, oils, coolants, and most industrial chemicals

• Stable under UV and moisture exposure

• Does not release toxic fumes under heat

These specifications explain why basalt woven tape performs reliably in harsh operating environments where both heat and mechanical load are constant concerns.

Key Properties and Performance Advantages

Basalt woven tape is valued for its balanced combination of strength, heat resistance, and safety. Below are the core performance advantages that differentiate it from conventional insulation materials.

High Thermal Stability

The tape maintains structural integrity even at high temperatures, making it ideal for use on exhaust systems, heat shields, and hot pipelines.

Non Combustible Fire Resistance

The mineral nature of basalt fibers ensures the tape does not ignite or support flame spread, offering excellent fire protection for hoses, cables, and nearby components.

Superior Abrasion and Vibration Resistance

Basalt woven tape holds up well against friction and vibration, which are common causes of insulation failure in automotive, generator, and industrial equipment.

Strong Mechanical Strength

The continuous fiber structure allows the tape to be wrapped tightly around components without tearing, fraying, or losing its shape over time.

Environmentally Safe and Non Toxic

Basalt fibers are free from chemical binders and do not emit harmful fumes, making the material suitable for sensitive industrial applications.

Common Applications of Basalt Woven Tape

Because of its exceptional heat and mechanical performance, basalt woven tape is widely used in industries that require reliable thermal protection.

• Exhaust pipe insulation for automotive and industrial engines

• Thermal wrapping for turbochargers and exhaust manifolds

• Fire resistant protection for hydraulic hoses and electrical cables

• Heat shielding for furnaces, processing lines, and high temperature machinery

• Protective layers in marine and aerospace systems

The tape can function as both a primary insulation material and an additional protective barrier in multi layer insulation assemblies.
