Polycat 35 catalyst CAS25441-67-9 Evonik Germany

Overview

Polycat 35 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 35 can also be used in MDI, TDI/MDI, MDI High Resilience (HR) soft molding foams as well as self-crusting and microcellular systems. It has a shelf life of 36 months.
