Characteristics and uses

Pentamethyldipropylenetriamine is a tertiary amine catalyst that balances the reaction of urethane (polyol-isocyanate) with urea (isocyanate-water) in various soft and rigid polyurethane foams;
Pentamethyldipropene triamine can improve the open porosity of the flexible foam and reduce the brittleness and adhesion of the rigid foam;
Pentamethyldipropene triamine is mainly used in the production of car seats and pillows, rigid polyether block foam.
