Notices:
PTFE needle felt are produced from 100% PTFE fiber which has been punched in three-dimentional structure. They have excellent features such as excellent flexibility, molding capability, high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance and anti-aging. 100% PTFE filter material can meet requirements in hostile environments of temperature fluctuating and acid & alkali in all PH range. The lifespan of PTFE filter material will be guaranteed for over 4 years as long as the temperature is controlled under the maximum operating temperature.

Hangzhou philis filter technology co.,ltd. has grown up to be one of leading manufacturer on dust filtration&spare parts in China.We have imported filter needle felt production line ASSELIN from France and we can produce very good quality non-woven products according customer's requirment.
Based on 8 needle felt production line ,our annual production ability can achieved 20,000 square meters per day . We can produce a large range of various filter fabric, such as polyester filter fabric, Acrylic filter fabric, Fiberglass filter fabric, PPS filter fabric, Aramid,P84 ,PTFE ,woven filter fabric and so on.
The most important thing is that we introduced German high technology to develop the first filter bag production line in China. Which help most filter bag production factory save a lot of human lab our cost but promote the work effection . The advanced technology and simple operation way of automatic filter bag production line has won a lot of customer’s praise.
