Performance Benefits
In low-catalyzed rigid urethane formulations, Lupranate M20S extends foam rise time by 20-30%, providing superior processing control for large rigid foam panels and molded flexible foams. The slower reactivity profile ensures optimal performance in demanding industrial applications.
Storage & Handling
Available in tank cars, tank trucks, and 250kg drums. Maintain storage temperature between 15-35°C to prevent viscosity changes and crystallization. Below 15°C, pumping and pouring become difficult, while temperatures below 0°C may cause crystallization.
Shelf Life
Six months when stored at 15-35°C with proper moisture exclusion.
Safety Notice: These products are used to prepare various polyurethane materials. Polyurethanes are organic materials and must be considered combustible. Follow all safety protocols during handling and processing.
