About Preshrunk Silica Needle Mat
Preshrunk Silica Needle Mat
Silica Needled Insulation enables the product to be easily cut and fabricated into intricate design configurations. Excellent thermal strength enhances high product value-in-use.
Silica Needled Insulation, made from amorphous silica, is ideal for a wide range of critical, high temperature applications. Silica Needled Insulation comes in in three thicknesses and can be Shrunk (nominal 5%) or Un-Shrunk (nominal 13%). It contains no shot (small spheres) which is important in certain insulation applications.
Silica Needled Insulation is designed to withstand temperatures up to 1,100 degree C. It is comprised of non-respirable, 9-micron filament fibers that are mechanically bonded and contain no added resins or adhesives. Density is 8 to 10 lb/ft3. Silica Needled Insulation is environmentally-friendly since it contains no harmful refractory ceramic fibers (RCF).

Customizable, Versatile Insulation SolutionsOffered as rolls or sheets and readily customizable in length, width, and thickness, the Preshrunk Silica Needle Mat accommodates both standard and unique project requirements. Its adaptability makes it suitable for gasketing, expansion joints, pipe insulation, and fireproofing across automotive, manufacturing, and industrial applications.
FAQ's of Preshrunk Silica Needle Mat:
Q: How is the Preshrunk Silica Needle Mat manufactured and treated for quality?
A: This mat is produced using a needle punching technique followed by a preshrunk process, which minimizes shrinkage under high heat (4% at 1000C). Its surface is uncoated and plain, ensuring optimal thermal performance and durability.
Q: What are the standard dimensions and can they be customized?
A: Standard dimensions are 1000 mm by 600 mm with available thicknesses of 6 mm, 12 mm, and 25 mm; further customization for length, width, and thickness is also possible, meeting specific project requirements.
Q: When should I choose this mat for my application?
A: Select this silica needle mat when your project demands high temperature insulation (continuous up to 1000C, short-term up to 1100C), chemical resistance (except to hydrofluoric and phosphoric acids), and non-flammability in industrial environments.
Q: Where is this product commonly used?
A: It is widely utilized in furnace and kiln linings, petrochemical installations, steel and metallurgy plants, automotive thermal protection, and for fireproofing, gasketing, expansion joints, and pipe or duct insulation.
Q: What is the main benefit of using preshrunk silica needle mat over other insulation materials?
A: The key advantage is its combination of high-temperature resistance, low shrinkage, and chemical resilience, ensuring long-lasting thermal insulation and fire protection in severe operational conditions.
Q: How is the mat packaged for distribution and export?
A: The mats are packed as rolls or sheets and further enclosed in PE bags or cartons, providing secure handling and safe transport, whether locally distributed or exported internationally.
