Dry strength agent
More Information
The main Description:
It is the copolymer of acrylamide and acrylic acids,using polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber.Its combination area of long chain polymers can be deformed,thus increasing the bond toughness.It could improve the tensile strength,stiffness, ring-crush strength, bursting strength, folding endurance and other physical index.And it also can improve the retention rate of the fine fiber and filler and drainage performance.
