About Silica Needle Mat

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).

Engineered for Extreme Temperatures

Designed to withstand continuous heat up to 1000C and short-term surges to 1200C, the Silica Needle Mat is ideal for insulating furnaces, reactors, kiln cars, and other high-temperature industrial equipment. Its high melting point (>1650C) and non-combustible, fireproof qualities provide reliable safety and protection.

Easy Handling and Versatile Application

The mat's flexible, lightweight structure makes it straightforward to cut, position, and fix in place. Available in 1-meter rolls or custom-cut sheets with standard widths of 600 mm, the product accommodates various installation needs for gaskets, linings, and heat shields.

Chemical Robustness and Durability

Manufactured from high-purity silica fibers, the mat demonstrates outstanding resistance to most acids-except hydrofluoric acid-and is unaffected by water, retaining its performance even in harsh conditions. Its durable, uncoated surface supports repeated repositioning and long service life.

FAQ's of Silica Needle Mat:

Q: How is the Silica Needle Mat installed and handled?

A: The Silica Needle Mat is simple to cut, handle, and fix due to its pliable structure. It can be easily shaped with standard cutting tools and quickly positioned for lining, shielding, or insulation tasks. Installation is straightforward, allowing for swift setup in industrial environments.

Q: What are the main benefits of using this mat for high-temperature insulation?

A: Key benefits include its ability to withstand continuous temperatures up to 1000C and brief exposure to 1200C, excellent fire resistance, minimal water absorption, high porosity for efficient thermal insulation, and outstanding resistance to most acids except hydrofluoric acid. It is also reusable and easy to reposition if needed.

Q: When should I use Silica Needle Mat over other insulation materials?

A: Use this mat for applications requiring high purity, reliable performance under extreme temperatures, and non-combustibility. It is ideal for environments where chemical stability (excluding HF acid) and low thermal conductivity are critical, such as furnaces, reactors, and fireproof linings.

Q: Where can this insulation mat be applied?

A: The Silica Needle Mat is suitable for industrial thermal insulation, fireproof lining in furnaces, kiln cars, reactors, heat shields, and gaskets. Its versatility also makes it effective in protective barriers, fire doors, and anywhere high-temperature, low-conductivity insulation is required.

Q: What is the process behind creating Silica Needle Mat?

A: The mat is produced by needle punching pure amorphous silica fibers into a cohesive, flat mat form. The process maintains the fibers' high purity (>96% SiO2) and creates a natural, untreated surface ensuring excellent thermal and chemical properties.

Q: Is the Silica Needle Mat reusable and safe to handle?

A: Yes, the mat is designed for repeated use and can be repositioned as necessary during installation or relocation. It's odorless, non-combustible, and contains no hazardous coatings, supporting safe handling in industrial settings.
