Dry Strength Agent

Product Description

Dry Strength Agent is an amphoteric polyacrylamide reinforcing agent with a network structure.  

The product is fully ionized in a wide PH range, which not only effectively improves the

hydrogen bonding force between the fibers, but also forms a more stable covalent bond

between the ionic groups. It significantly improves the tensile strength, annular compressive

strength, break resistance and interlayer bonding force of the paper, and also has the function

of helping filter and improving sizing efficiency.

2)Recommended Use

The products are mainly used in box board paper, yarn tube base paper, high strength core paper and so on.

3)Recommended Levels

Dilute water 10-20 times and disperse evenly before adding into the slurry, adding the amount of 10-20 kg/ton paper or adjust according to the production needs;
