Application of thermosensitive catalyst SA-1 in polyurethane components in aerospace field

Introduction

The aerospace field has extremely strict requirements on materials. It not only requires the materials to have high strength, lightweight, high temperature resistance and other characteristics, but also requires the materials to maintain stable performance in extreme environments. Polyurethane materials have been widely used in the aerospace field due to their excellent mechanical properties, chemical corrosion resistance and processability. However, the properties of polyurethane materials depend heavily on the catalysts used in their preparation. As a novel catalyst, the thermosensitive catalyst SA-1 shows great potential in the preparation of polyurethane components due to its unique properties. This article will introduce in detail the application of the thermally sensitive catalyst SA-1 in polyurethane components in aerospace field, including its product parameters, application scenarios, advantages and future development directions.
