Product Description Polymeric Mdi for Polyurethane System InsulationProduct Description Lupranate?M20S is a polymeric MDI with a functionality of approximately 2.7. Lupranate M20S is suitable for the production of rigid insulation foams by molding, spraying, and frothing. It is also used for rigid and semi-flexible integral skin foams, adhesives, sealants, elastomers, and high-resiliency flexible foams. Inlow catalyzed rigid urethane formulations, the foam rise time can be lengthened by 20-30%. The slower reactivity can be advanta- geous in applications such as large rigid foam panels or molded flexible foams.Product Parameters1AppearanceDark Brown Liquid2NCO Content, wt. %31.53Viscosity @ 25°C, cps2004Hydrolyzable Chlorine, wt. %0.0355Flash Point, °C (COC)2006Density @ 25°C, g/cm31.237Initial Boiling Point, 5 mm Hg, °C1908Vapor Pressure @ 25 °C, mm Hg0.0002ApplicationIsocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, polyurethane (PU) coating, polyurethane (PU) adhesive, Seepage-proofing, structure foam, sealants, microcellular integral skin foams,automobile bumper, high resilience etc.With good performance such as very good fluidity, very good foaming capacity, strength well, dimension stability etc. Packaging & ShippingPackaging250kg/drum ,12500kgs/ IBCShelf LifeThe shelf life of Lupranate M20S is six months if the temperature is maintained at 15-35°C and moisture is excluded.Storage Lupranate M20S is supplied in tank cars, tank trucks, and drums. Once a container has been opened, care should be taken to exclude moisture. The most favorable temperature for storage is 15-35°C. If stored at higher temperatures, or if moisture is not excluded, an undesirable increase in viscosity will occur. Below 15°C, the product becomes difficult to pump and pour. Below 0°C, crystallization may occur.Warning These products can be used to prepare a varietyofpolyurethaneproducts.Polyurethanesare organic materials and must be considered combustible.Company Profile
