Non-Toxic PU Catalysts

Tin-Free and Mercury-Free Non-Toxic PU Catalysts for Rigid PU Foam, Silicone and Resins

LPR’s PU catalysts are non-toxic, environmentally-friendly organometallic catalysts for efficient polyurethane synthesis with minimal health and ecological concerns. Our catalyst compounds are based on silver, bismuth, and zinc, which prevent the growth of fungi. We offer 9 best-selling non-toxic PU catalyst samples for testing.

 

Manufactured at ISO9001/14001 certified facilities in South Korea, the non-toxic catalysts exemplify our manufacturer’s focus on the environment as well as their technical expertise with polyurethane, PU compound. For rigid PU foam production, the PU catalysts are based in potassium, zinc or silver; they are tin-free or mercury-free while achieving your reaction rate for the PU foam. Our customer list includes Dow Chemical, Dow Corning, Huntsman, Asia Polyurethane, BASF, and Baalbaki among others.

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.
