Aimed at the the fact that SOx exists in the filtration, our company customerized this new type of filter media.

We select two or more types pf staple fibers to produce this needle felt.

After the process of calendering, singeing and impregnation, the felt has the features of strong acid resistance, anti abrasion, smooth, and so on.

It can be widely used in the cement, power plants, porcelain industry etc.
