1. Permanent flame retardancy, self-extinguishing, with no smoldering or dripping. It resists welding slag and helps prevent flame spread.
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.
