E-class woven fiberglass filter cloth fabircs are the optimum solution for dust collection systems with working temperature 150-260ºC. ECOGRACE develop and research the chemical finish on the fiberglass filter cloth to fully utilize the chemical and physical function. it includes PTFE membrane, PTFE dipping, Graphite treatment, silicon treatment, PTFE Fiberglass Filter Bags.


ECOGRACE finished woven fiberglass bags are successfully used in reverse air dust collection system, pulse jet bag filter dust collection system and shaking vibrating dust collection system. The applied including cement plant, carbon black processing.

1) Features:

1. High temperature resistant , it can work for a long time under 260°C.

2. Smooth surface is good for easy dust cake releasing , energy saving . 

3. Steady size,non shrinking under proper temperature.

4. Intensity high, obstruction more than 99% code thickness.


3) Industrial applicaiton:
 
1. Cement plant, coal boiler, waste incinerators;

2. Carbon black production, refineries, steel mills;

3. Foundary/metal smelting furnace, metal smelting;

4. Non ferros alloy plant, paper plant, glass production plant.

ECOGRACE Fiberglass Filter Bag Chemical Finishing :
 
GSP finished: 
It consists blend of silicon oils, graphite & PTFE ( Teflon ). The three finishes components combine to protect the glass fabric from abrasion , but offer only limited protection from chemical attack. The GSP finish is now widely primarily in cement production and metal foundry applications .

PTFE finished:
10 % addon of PTFE particles encapsulates the glass fibers to prevent abrasion.Recommended for use with utility base load boilers operating under mild pH conditions.


Acid Resistent treatment ( AR ): 
Consists of acid resistant polymers,PTFE , graphite , and silicon treatment . Recommended for filtration of flue gases in industrial utility boilers and acid environments such as carbon black and fossil fuel burning power generation . 
 
E-PTFE membranes: 
Coated with e-PTFE membranes

With the surface finished, it enjoys such characters as smooth, much lower emission , high temperature resistant , chemical corrosion repellent , high tensile breaking strength ,easy cleaning .
