Product Description

P*4 Fiber Features
1.Excellent steady under high temperature and resistance to acid,
2.High filtration efficiency , high tensile strength
3.Low back washing pressure, maximum flexibility
4.Excellent dust cake release
P*4 needle punched felt
 
1. Prominant heat-resistance with working temperature up to **0
2. Great chemical-resistance. In the past *0 years, P*4 has been widely recognized for its key value in dealing with the acid waste gas and alkalescent dust from incineration procedure of garbage.
3. low backwashing pressure and high disengaging efficiency.
 
Heading Promise **0% high quality pure P*4 material,use the most advanced production machine to produce top quality p*4 needle felt,nowadays we are supplying to American, Middle-East,South-East Asia and domestic market.
