Glass Fiber Needle Felt is a non-woven fabric manufactured by needling chopped E-glass fibers (SiO₂ 52-56%, Al₂O₃ 12-16%). Fibers are short-cut to 50-90 mm lengths, carded into a web, and mechanically reinforced via high-density needle punching (thousands of barbs per m²). This process creates a 3D microporous structure with >90% porosity, enabling superior filtration, thermal insulation, and acoustic absorption.
| Industry | Applications |
|---|---|
| Industrial Filtration | Baghouse dust filters for steel, cement, carbon black, and waste incineration plants (filtration velocity: ≤1.0 m/min) |
| Thermal Insulation | Boilers, HVAC pipelines, automotive engine hood pads, household appliances (microwaves, ovens) |
| Transportation | Automotive mufflers, aircraft cabin walls, ship bulkhead fireproofing |
| Construction | Sandwich layers for color steel plates, timber-framed wall insulation (Fire Class A1) |
Compliant with industry standards (e.g., JC/T 590-1995), parameters for common grades are listed below:
