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.
