1.High flocculent ability and good thickening ability.
2.Easier to form large flocs.
3.better than APAM in acidic condition.
non-ionic Polyacrylamide(NPAM)
CAS No: 9003-05-8
Introduction:
This product is technically named Polyacrylamide, which is a water soluble macromolecular polymer. It is insoluble in most organic slovents. It generates a good flocculation and reduces the resistance between liquids.
Main usages :
Due to a certain amount of polarity gene in NPAM's molecular chain which can absorb the solid particulates suspending in the water, it is easier to form large flocs. It is the most appropriate to use NPAM, when the sewage is acidic. It is better to use NPAM in conjunction with inorganic salts such as inorganic flocculant poly iron and poly aluminum. It is also used as agents for the textile pulp, paper chemicals, water shutoff agent, and etc.
Because of its non-ionic functional group, PH value and salts have a little influence on NPAM's flocculation. In the neutral or alkaline conditions, the flocculation effect is not as good as APAM, but better than APAM in acidic conditions.
Specifications:

Application Method & Notes:
It is recommended to prepare the product in water solution at 0.1% concentration. It is proposed to use the neutral and desalted water.The product should be scattered evenly in the stirred water, and the dissolving can be accelerated by warming the water (below 60°C).The most economical dosage can be determined based by a preliminary test.The solid product is packed in inner plastic bags and further in polypropylene woven bags with each bag containing 25Kg. The colloidal product is packed in inner plastic bags and further in fiber plate drums with each drum containing 50Kg or 200kg.This product is hyqroscopic, so it is should be sealed and stored in a dry and cool place below 35°C.The solid product should be prevented from leaking on the ground because the hygroscopic powder can make the floor slippery.
