Product Description Product DescriptionPolymerized MDI Isocyanate Wannate PM200We have been working closely with Wanhua, Huntsman, and Covestro for many years, with a total sales volume of more than 20 million USD in domestic and international markets.Wanhua: PM200, PM400Huntsman: 5005,5008Covestro: 44V20LPerformance Reference:PM200=5005=44V20LPM400=5008Application Isocyanates MDI is extensively application in most of field, such as thermal insulation rigid foam, PU coating, PU adhesive, Seepage-proofing, structure foam, Automobile bumper, high resilience etc. With good performance such as very good fluidity, very good foaming capacity, strength well, dimension stability etc.Product Parameters Typical Physical and Chemical Properties UnitContentAppearance-Brownish LiquidViscosity(25oC)(mPa·s)150-250NCO Content%30.5-32.0Density (25oC)(g/cm3 )1.220-1.250Acid Content%≤0.030Hydrolysable Chlorine%≤0.20Package(s) Standard Packing:Iron Drum N.W.: 250KG/Iron Drum Can also according to your requirment to packing.MDI Properties appearence: Brown transparent liquid; boiling point (oC): 200~208; stability: stable. Incompatible with strong oxidizing agents, alcohols. May decompose in moist air, or on contact with water.Storage Since WANNATE? PM-200 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product. Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen. Containers of WANNATE? PM-200 should be kept properly closed and stored indoors at ambient temperature (15-35oC) in a well-ventilated area. Storage at low temperature (below 5oC) may lead to some crystallization; this material must, therefore, be protected from frost. If crystallization does occur, the material should be heated by rolling the drum in a hot air oven at 70-80oC to melt it out, and should then be thoroughly agitated before use. Melting in a water bath is not recommended.Extended storage at temperatures above 50oC is not recommended to prevent from the formation of insoluble solids and viscosity increase.Shelf Life Under recommended storage conditions, the shelf life of WANNATE? PM-200 is one year since the date of production.
