Thermal-sensitive catalyst SA-1: Strategies to reduce defects in polyurethane products

Introduction

Polyurethane (PU) is a multifunctional material widely used in automobiles, construction, furniture, footwear and other fields. However, various defects are often encountered in the production process of polyurethane products, such as bubbles, shrinkage holes, uneven surfaces, etc. These defects not only affect the appearance of the product, but may also reduce its mechanical properties and durability. To solve these problems, the thermal catalyst SA-1 came into being. This article will introduce in detail the characteristics, applications of the thermosensitive catalyst SA-1 and its strategies in reducing defects in polyurethane products.

Overview of thermal-sensitive catalyst SA-1
