          Features            

l  Excellent cohesion

 It can greatly improve the physical properties of polyurethane materials, such as mechanical strength.


l  Superior hydrolysis resistance

Improve product hydrolysis stability: PPCD itself has a hydrophobic structure, its hydrolysis resistance is equivalent to that of polyether type, and its water absorption rate is lower than that of polyether type.


          Application          

It is suitable for the production of polyurethane materials with excellent mechanical strength and hydrolysis resistance, especially for the production of leather resins.
