Non-Toxic Catalyst Family Compared to Organotin Substances
Used polyurethane foam is a source of environmental pollution as it emits high levels of carbon dioxide during disposal. LPR Global supplies tin-free and mercury-free metal catalysts, developed and patented polyurethane recycling technology that is now utilized by a global refrigerator manufacturer. Our flagship catalyst series are the tin-free and non-toxic metal catalysts, which are supplied to 50 global companies in 35 countries.
Non-Toxic Polyurethane Catalyst
Based on silver, bismuth, and zinc, these catalysts replace mercury and lead-based catalysts; they can be used alone or in combination with additives and other organometallic compounds. Depending on your application, you can control the reaction rate of these catalysts by using an amount identical to DBTDL catalysts. They are formulated to promote NCO/OH reactions with high hydrolytic-stability and to allow the coordination of amines, rather than catalyzing NCO/H2O reactions in one component polyurethane.
