Optimizing Catalyst Selection for Rigid Foam Applications

Introduction

Choosing the correct balance of blowing and gelling catalysts is critical for rigid polyurethane foams used in insulation. This guide explores the synergistic effects of tertiary amine catalysts.

Blowing vs Gelling

Blowing catalysts promote the reaction between isocyanate and water, generating CO2. Gelling catalysts promote the urethane reaction.
