P84 High-resistant Temperature Needle Felt

P84 High-resistant Temperature Needle Felt a kind of functional fiber, is not only economical but high-powered among varies high-temperature fibers, which outweighs others in the aspects of strength, modulus and with the characteristics of without creeping in the long-term heating, good dimensional stability, small thermal expansion, resistance to chemical corrosion and high-temperature flame retardant, etc.

The filter cloth made of P84 can keep its dimensional stability in the range of 100-200a , while declining if place it in hydrochloric acid, nitric acid, sulfuric acid and sodium hydroxide, resistance to bleach and solvent.
