Polycat DBU catalyst CAS6674-22-2 Evonik Germany

July 4, 2023by admin0

Overview

Polycat DBU is a tertiary amine-based foaming catalyst that facilitates urea (water-isocyanate) reactions in a variety of hard and soft polyurethane foam applications. It is the industry standard foaming catalyst for soft foams and is used in TDI-based soft foam systems such as mattresses, seats, and automobiles. It is also used in combination with trimer catalysts in PIR laminated paperboard formulations. Polycat DBU is also available for MDI, TDI/MDI, MDI High Resilience (HR) flexible molding foams as well as self-crusting and microcellular systems. It has a shelf life of 36 months.
