Features
l Excellent cohesion
It can greatly improve the physical properties of polyurethane materials, such as mechanical strength, adhesion, abrasion resistance, and scratch resistance.
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 producing polyurethane materials with excellent mechanical strength and hydrolysis resistance. At present, this grade is widely used in water-based polyurethane PUD, high-performance leather resin and other fields.
