CSIAH-120



   



Polymeric type Anti hydrolysis Agent
CSIAH-120 can effectively restrain the mechanical properties degradation of TPU, polyester polyurethane adhesives, and polyurethane shoe-sole systems based on polyester polyols, caused by hydrolysis as a new anti-hydrolysis agent.

CSIAH-120 can close the active carboxyl-terminated end of the polyester. Furthermore, it can repair the amputated molecules by cross-linking with carboxyl groups, thereby prolonging the service life of the products. polyester polyurethane adhesives/ polyurethane shoe-sole systems based on polyester polyols 

CSIAH-120 can significantly improve the anti-hydrolysis resistance (tensile strength, elongation, melt viscosity and acid content) of TPU, polyester polyurethane adhesives, and polyurethane shoe-sole systems based on polyester polyols. The recommended dosage is 0.5-2.0 phr. Especially used to reduce the acid value, the amount can be adjusted according to the initial acid value and the final acid value
