- Stable chemical and physical properties;
- Excellent flame retardancy, no molten drops, no carbon gathering, no shrinkage and no deformation by fire;
- Strong corrosion resistance;
- Resistant to various solvents, acids and bases;
- Strong temperature resistance, low hygroscopicity, long service life;
- Low resistance, high dust capacity.
It is mainly used for primary filtration in ventilation equipment, dust removal equipment and air supply systems in various high temperature and fireproof environments.
