Introduction

In modern industry, polyurethane (PU) materials are widely used in automobiles, construction, furniture, shoe materials and other fields due to their excellent physical properties and chemical stability. With the increase of environmental awareness and the demand for energy conservation and emission reduction, the lightweight design of polyurethane products has become an important development direction in the industry. As a highly efficient catalyst, the tertiary amine catalyst LE-530 plays a crucial role in the lightweight design of polyurethane products. This article will introduce in detail the characteristics, application of the tertiary amine catalyst LE-530 and its important role in the lightweight design of polyurethane products.

1. Overview of LE-530, tertiary amine catalyst

1.1 Basic concepts of tertiary amine catalysts

Term amine catalysts are a class of compounds containing three organic groups connected to nitrogen atoms, and are widely used in polyurethane foaming reactions. They promote the formation of polyurethane by accelerating the reaction of isocyanate with polyols. The selection of tertiary amine catalysts has an important influence on the performance, foaming speed, cell structure, etc. of polyurethane products.
