Industrial Dust Non-woven PTFE Needle Felt Filter Cloth
1.Brief Introduction Of PTFE Needle Punched Felt
Be composed of 100% pure PTFE;
Can operate at 240 °C continuously;
Acid and alkali Resistance, corrosion resistance,have strong chemical stability (0-14 PH)
Can be used under high humidity environment;
Low shrinkage rate even if under high temperature,
Aging resistance;
No enviroment pollution
2.General introduction of the PTFE Filter Fabrics
PTFE (polytetrafluoretyhylene) also called Teflon, which be treated as the KING of the plastics due to the properties of the high temperature resistance, corrosive resistance, durable, which is a innate excellent materials for industrial filtration.
Anhui Yuanchen adopted the first grade PTFE (Teflon) fiber and sound workmanship needle punched into felt, after the special finish treatment, the Teflon needle felt filter cloth can be widely used in various industrial occasions for dust collection (PTFE dust filter bag ) and liquid filtration (Teflon micron rated filter bag ).
