product detail

Material：

polyester filter bag are made of 100% filament polyester fiber,after needle punched, singed heat set calender for the raw polyester filter felt material, then polyester filter felt can be sewn into polyester filter bags.

Available Finish: singed,calendar,heat set PTFE membrane,W/O,anti-static treatment.

Advantage:

Polyester bag filters Breaking Elongation is less than 20% for MD and 40% for CMD,low dry shrinkage, can work well in the 130 deg C. the material is cheaper than other material, so widely used in a lot of bag house system.
