Our flame retardant polyester needle felt is a new type of carbon coated filter material. We use a special surface treatment process to extend its performance and service life.
- Material: polyester staple fiber, carbon powder.
- Scrim: polyester staple yarn.
- Width: ≤2.2m.
- Thickness: 1.7mm.
- Weight: 400-600g/m2 ±10%.
Description
If you need fire-retardant materials for a filtration or dust collection system, fire-retardant polyester needle felt can provide a reliable and cost-effective solution. It is a specialized non-woven fabric designed to resist ignition and slow down the spread of flames. It is commonly used in applications where fire safety is a critical requirement.
- Protection from flying sparks.
- Resistant at high temperatures.
- Long operational life.
- Flame retardant.
- Good acid, alkali and hydrolysis resistance.
- Excellent wear resistance.
- High quality and economical.
Customizable Colors
Advantages Over Other Materials
- More cost-effective than inherently fire-resistant fibers like aramid or modacrylic.
- Easier to process than fiberglass while still providing good fire protection.
- Can be recycled (if untreated with hazardous chemicals).
