Silica Needlemat
Silica Needlemat for High Temperature Insulation
At Textile Technologies Europe Ltd, we supply high performance silica needlemats engineered for demanding thermal insulation applications across industrial, power generation, and transportation sectors.
Our needlemats are manufactured from 100% amorphous silica fibres, mechanically needled without any chemical binders, offering superior thermal stability, dimensional integrity, and resistance to temperatures up to 1000°C in optimum conditions.
These non-woven felts provide low thermal conductivity and excellent flexibility, making them ideal for insulating complex shapes, cavities, and high-temperature assemblies such as turbines, combustion chambers, furnaces, exhausts, and ducting systems. In particular, silica needle mat is most commonly used as a middle insulation layer in high specification insulation jackets.
Unlike traditional E glass-based felts, silica needlemats offer significantly higher heat resistance and are non-irritating to handle, with no added resins or bonding agents.
Our Range of Silica Needlemats Includes:
-
Standard Silica Needlemat (96%+ SiO₂ content)
-
Silica Needlemat with Aluminium Foil Lamination
-
Adhesive-Backed Silica Felt
-
Silica Needlemat Reinforced with Glass Cloth
-
Custom Die or CNC cut Silica pieces cut to drawing specifications
Available in thicknesses from 4mm to 25mm and densities from 120kg/m³ to 250kg/m³. We offer rolls, sheets, or fabricated components to suit your application requirements.
What is silica needlemat used for?#
Silica needlemat is used as a high-temperature insulation layer in industrial furnaces, exhaust systems, gas turbines, and thermal enclosures. It provides radiant heat protection, acoustic damping, and fire resistance in safety-critical environments.
How is silica needlemat manufactured?
The mat is formed by layering chopped silica fibres and mechanically needling them to create a strong, flexible structure. No binders or adhesives are used, making it safe for high-temperature applications.
Can silica needlemat be customised?
Yes. We can supply adhesive backing, foil facings, or stitch-bonded versions for improved dimensional stability. Custom cutting and lamination services are also available.
What temperature can this insulation withstand?
Silica needlemat can resist continuous exposure up to 1000°C, with minimal shrinkage (up to 8%). This makes it a superior choice to glass-based alternatives, which typically degrade above 750°C.
Is this product safe to handle?
Yes. Silica fibres are soft and non-irritating compared to glass or ceramic-based materials. They are free from mineral silicates and ceramic fibres, reducing handling concerns and making them suitable for applications involving direct contact or confined workspaces.
