ECOGRACE is always specializing in reaching and manufacturing filtration material and dust collector filter bags. Our main filter products including the Nomex Filter bags, PPS filter bags, Acrylic filter bags, P84 filter bags,etc.  We will provide more effective filtration solutions for all industries like Asphalt mixing, steel mill, thermal power plant, Biomass boiler, cement plant,etc.

Application:

PPS(Ryton) Filter Bag is widely used in coal-fired boilers, also used for waste incinerators, coking furnace, kiln furnace, chemical dry process of flue gas cleaning processes, also using in carbon black, powder collect, pneumatic conveying, cement industry, and so on. When due to chemical attack and hydrolysis causes, can not use Aramid, PPS(Ryton) Filter Bag can be substituted.

Performance:

PPS(Ryton) Filter Bag will be applied in the gas  continuous  temperature up to 160°c, instant heat resistant up to 200°c.
Chemical structure of PPS RYTON filter media is simple and strong and stable , it has excellent performance of acid and alkali resistance!
Excellent hydrolysis resistance capability, and strong chemical stability.
Good flame retardant  and excellent heat resistance function. Disadvantage is that antioxidant performance of PPS(Ryton) Filter Bag is poor, easily occur oxidation-corrosion.It is suitable for gas with  O2 composition < 10%.

Application:

Nomex Filter Bags is mainly used in cement industry, asphalt industry, metallurgical industry and tobacco industry for  flue gas purification.

Performance:

Nomex Filter Bags continuous operating temperatures is up to 200°c, instant service temperature is up to 240°c.
Nomex Filter Bags fire retardant performance is excellent,
Corrosion resistance and alkali resistance is good,
Excellent thermal stability, excellent abrasion resistance and flexural resistance. Hydrolysis resistance is poor, when SOx and vapor in flue gas or dew point is frequent, it would greatly reduce its service life.

Application:

P84 FILTER BAGSis mainly used in drying, burning, smelting, industrial kilns, coal-fired boilers and waste incineration process of flue gas purification.
P84 FILTER BAGS is applied the gas continuous operating temperature is up to 240°c, instant operating temperature is up to 260°c.
P84 FILTER BAGS is made with flame retardant fiber, has excellent resistance to chemical corrosion.
Good resistance to hydrolysis.
P84 FILTER BAGS a large filter surface area, with excellent filtration performance, in favor of cleaning of filter bag.
P84 FILTER BAGS is  applicable to gas with chemical harsh conditions , normal performance in the gas in oxidation and hydrolysis.

Application:

PTFE filter bags is higher in cost compared with other filter bags .It is suitable for the corrosion resistance of harsh condition where require a longer working life of dust filters , such as waste incineration flue gas filtration.
PTFE filter bags  has excellent chemical stability and heat resistance.
PTFE filter bag will  withstand all strong acids and alkali erosion.
PTFE filter bag will serve well for gas continuous operating temperature  up to 240°c, instant temperature  up to 280°c.
It will  withstand all kinds of strong oxidant corrosion, hydrolysis performance is excellent;
Good flame retardant, insulation, heat insulation, light stability, low coefficient of friction and small adhesion.
PTFE filter cloth has excellent filtration efficiency, low and stable differential pressure, easy cleaning, and under the same conditions its life is far more than other high temperature resistant  filter materials.
