Polyurethane gel amine catalyst 33LV: a new era catalyst to accelerate the process of polyurethane reaction

Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, packaging, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, in the production process of polyurethane, the selection of catalysts has a crucial impact on the reaction rate, product quality and production cost. In recent years, with the advancement of science and technology, new catalysts have emerged continuously.

The synthesis of polyurethane mainly involves two reactions: the addition reaction of isocyanate and polyol (i.e. polyurethaneization reaction) and the reaction of isocyanate and water (i.e. foaming reaction). Both reactions require catalysts to speed up the reaction process.

  • Polyurethaneization reaction: Isocyanate (R-NCO) reacts with polyol (R’-OH) to form polyurethane (R-NH-CO-O-R’).
  • Foaming Reaction: Isocyanate reacts with water to form carbon dioxide (CO?), and CO? acts as a foaming agent to expand the polyurethane material.
