Polyurethane: A Pivotal Component in A Wide Range of Applications
Polyurethane is an essential polymer, renowned for its versatility and adaptability across a multitude of industrial applications. Its popularity is primarily attributed to its unique chemistry, enabling the fabrication of materials with a vast spectrum of different potential mechanical and physical properties. Thus polyurethanes are used in a wide range of applications including, coatings, adhesives and sealants, plastics and foams.
The adaptability of polyurethane also lies in its unique chemistry, which allows for the creation of products with a wide range of hardnesses, flexibility, and densities[1]. Polyurethanes are primarily produced through the reaction of a polyol (an alcohol with multiple reactive hydroxyl groups) and an isocyanate, often catalyzed by various additives including tertiary amines and metals such such as inorganic tin, organotins, bismuth, zinc, zirconium and and iron.
The production of polyurethanes is a complex process requiring precise control over the specific reactions that occur during polyurethane synthesis. This is where catalysts play a critical role. They help to advance the polyurethane-forming reactions and control the polymer structure, thereby significantly influencing the properties of the resultant polyurethane.[3]
Reaxis Metal-Based Polyurethane Catalysts: Enhancing Efficiency and Performance
Metal-based catalysts used in polyurethane synthesis are used to selectively accelerate both the polymerization and crosslinking reactions. Tin and bismuth catalysts are ideal for catalyzing the hydroxyl/isocyanate reaction whereas Zzinc catalysts are primarily active for the crosslinking reactions. The functionality of these metal catalysts can be enhanced via ligand selection. For example, sulfur-based ligands enhance the selectivity of the hydroxyl/isocyanate reaction (versus the water reaction) and build in front-end reaction delay.
Reaxis offers a wide range of tin, bismuth and zinc catalysts for polyurethane formulation development. Common inorganic tin catalysts supplied include REAXIS® C125 (Stannous Neodecanoate) and REAXIS® C129 (Stannous Octoate).
