Glass Fiber Needle Felt : High Temperature Insulation For Industrial And Automotive Applications

1. Product Introduction

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.

2. Production Process

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.

3. Usage Precautions

Storage: Keep in dry, cool environments (15–35°C) away from humidity and direct sunlight.
Temperature Limits: Operate within -40°C to 850°C (short-term exposure up to 1000°C for high-grade variants).
Chemical Compatibility: Resistant to oils, fuels, and solvents; avoid contact with strong alkalis or acids.
Handling: Wear PPE (gloves, masks) to prevent fiber irritation; use sharp tools for cutting.
