YJ # 801

Application

Modified MDI,is a mixture of polyol-modified diphenylmethane diisocyanate and polyphenylmethane polyisocyanate. It is a light brown liquid at room temperature. It can be mainly used in the production of rebounded foam.

Package

200 liter iron drums, 230+/-1kg/drum

Storage

Since YUNJIE#801 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#801 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.

Shelf Life

Under recommended storage conditions, the shelf life of YUNJIE#801 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.

Safety

YUNJIE#801 is of low toxicity by inhalation and skin absorption. The very low volatility of YUNJIE#801 means that it should be of little hazard for brief exposures under normal conditions, e.g. in cases of small spillages.Nevertheless, YUNJIE#801 is an isocyanate-based composition and should be of certain toxicity. It may cause mild eye irritation and slight skin irritation. It may pose problems of skin sensitization. YUNJIE#801 has a Ceiling Threshold Limit Value,TLV(C) of 0.02ppm(0.2mg/M3).
