2. Excellent temperature resistance: continuous use up to 130°C; peak temperature 150°C.

3. High strength and wear resistance, with resistance to acids and alkalis, as well as hydrolysis resistance. Good air permeability.

4. Halogen-free or low-halogen options; RoHS compliant; eco-friendly.

5. Lightweight and flexible—easy to cut, punch, and process into various shapes.

6. Cost-effective with stable performance and better overall properties than wool felt and ordinary polyester felt.

Application
 



1. Dust filtration
Filter bags for cement plants, power plants, metallurgy, and woodworking; explosion-proof treatment for aluminum and magnesium dust.
2. Automotive and rail transit
Thermal insulation for engine bays, interior sound insulation, and fireproof pads for battery compartments.
3. Industrial sealing and protection
Fire door sealing strips, equipment shock-absorbing pads, and welding protective felt.
4. Building and fire safety
Fire barriers, flame-retardant sound insulation layers, and temporary fireproof coverings.
