YJ # 906
Modified MDI,is a mixture of polyol-modified diphenylmethane diisocyanate and polyphenylmethane polyisocyanate. It is a brown liquid at room temperature. It can be mainly used in the production of rebounded foam.Tasteless, NCO18.5.
200liter iron drums, 230+/1kg/drum
Since YUNJIE#906 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble areas 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 YUNJIE#906 should be kept properly closed and stored indoors at ambient temperatures (15-25 ℃ )in a well-ventilated area. Storage at low temperatures (below 10℃) may lead to some crystallization; this material must, therefore, be protected from frost. If crystallization does occur, the material should be heated to 70-80℃ to melt it out, strictly prohibit to heat over at local part and should then be thoroughly agitated before use.
Under recommended storage conditions, the shelf life of YUNJIE#906 is six months. If the production is overdue, but it’ s main physical and chemical properties in the guide line, may not effect on it’ s using properties.
