There are 840A,840B,750AB 4212
Polypropylene filter can be divided into short polypropylene fiber and long polypropylene filter cloth. The yarns which are made of long polypropylene fiber are very slippery. So the bursting strength and gas permeability of the long polypropylene are much better than that of the short poly-filter cloth. The surface of industry filter-cloth which are made of polypropylene fiber is very smooth. So it is suitable for powder filtering. Moreover, the products which we has just developed,is the best filtration material for the fields of chemical and medicine,but it is not suit for power filtration. The product of 4212 which are made of short polypropylene filter cloth. so it is the filtration material for the dyestuff factory,the effect of acid spotting and gas permeability are as far times as 120-17 of polyester, so it can speed up the velocity of filtration,and also avoid walling yo draff.
