Glass Fiber Needle Felt is a non-woven composite material engineered for exceptional thermal insulation, sound absorption, and mechanical durability. Composed of inorganic glass fibers bonded through a needle-punching process, it offers a lightweight yet robust solution for high-temperature environments. This product is resistant to corrosion, chemical degradation, and thermal shock, making it ideal for applications demanding reliability in extreme conditions, such as automotive exhaust systems, industrial furnaces, and aerospace components.
Step | Description |
---|---|
Material Preparation | Glass fiber rovings are cut into specific lengths (1.5-3 inches) for uniform distribution. |
Binder Application | Fibers are bonded using polyester, epoxy, or PTFE binders for structural integrity. |
Needle Punching | Barbed needles mechanically interlock fibers to form a dense, non-woven mat. |
Curing | Heat treatment activates binder curing, ensuring dimensional stability. |
Quality Control | Parameters like weight (30-500 gsm), thickness (2-25 mm), and thermal resistance are tested. |
Parameter | Standard GNF | High-Temperature GNF |
---|---|---|
Basis Weight | 30-500 gsm | 800-1000 gsm |
Thickness | 2-25 mm | 5-25 mm |
Tensile Strength | ≥40 N/50 mm (MD) | ≥60 N/50 mm (MD) |
Thermal Conductivity | 0.035 W/m*K (room temp) | 0.025 W/m*K (850°C) |
Flammability | Self-extinguishing | Non-combustible |
Certifications | ISO 9001, RoHS, REACH | ISO 9001, UL 94 |
