Application:

PTFE needle felt dust filter bag is more suitable for the need to withstand the harsh conditions of corrosion resistance, high filter life requirements of the occasion.

Product details:

Polytetrafluoroethylene—PTFE membrane Needle Felt also named as Teflon Needle felt is made from 100% PTFE fiber which has been punched in three-dimentional structure. The surface of polyetrafluorethylene (PTFE) membrane is smooth and anti-chemistry. FTFE Needle Punched Felt is the most high-end material for the filter bags, Any PH value with acid or alkali erosion is no effect to the PTFE needle punched felt at 240 ℃ continuous operation temperature and 260 ℃ instant temperature conditions. Polytetrafluoroethylene synthetic fiber filter bags is excellent self-lubrication, waterproof, can withstand ultraviolet radiation.
