Polyurethane: A Pivotal Component in Industrial 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 mechanical and physical properties. Thus polyurethanes are used in a wide range of applications including, coatings, adhesive and sealant, plastics and foams.
The adaptability of polyurethane lies in its unique chemistry, which allows for the creation of products with a wide range of hardness, 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 compounds such as inorganic tin and organotin catalysts[2].
However, the production of polyurethane 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 expedite 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 polymerization and crosslinking reactions. Tin and bismuth catalysts are ideal for catalyzing the hydroxyl/isocyanate reaction. Zinc catalysts are primarily active for the crosslinking reactions. 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. Common inorganic tin catalysts supplied include REAXIS®C125, Stannous Neodecanoate, and REAXIS®C129, Stannous Octoate. Common organotin catalysts supplied include a wide range of octyl-, butyl-, and methyl-based products including REAXIS®C218, Dibutyltin Dilaurate, REAXIS®C233, Dibutyltin Diacetate, REAXIS®C216, Dioctyltin Dilaurate, REAXIS®C325, Dimethyltin Dineodecanoate, and REAXIS®C228, Dioctyltin Diacetate.
