PRODUCT CHARACTER-
ISTICS
Polymeric Methylene Diphenyl Diisocyanate (MDI) is used in the manufacture of various products, including rigid foam, semi-rigid foamand CASE. Polymeric MDI is classified into a variety of grades according to viscosity, among which users can choose the most suitable for their purposes. The characteristics of each of the major products areas follows:
- COSMONATE M-100
Polymeric MDI having low viscosity and low functionality, this product features outstanding compatibility with PPG, along with excellent flowability and moldability.
- COSMONATE M-200
The most widely used product among the Polymeric MDI, it is commonly used for various manufacturing purposes, such as the production of rigid polyurethane foams and semi-rigid polyurethane foams.
- COSMONATE SR-3001C, SR-500, SR-550
A high-viscosity polymeric MDI with high functionality, it is suitable for the production of Rigid PIR foams, due to its excellent flame retardancy and high compressive strength.

HANDLING AND STORAGE
Contact with water must be avoided during use and storage, as these products generate insoluble urea on contact with water. Packing containers must be charged with inert gas such as nitrogen and air tightly sealed, and stored at 15~35°C. Careful attention must be paid to storage times, as both physical and chemical properties deteriorate with time. Figures 1 and 2 at front page indicate the expected variability of NCO content and viscosity over time at different temperature ranges.
SAFETY AND HEALTH
May cause inflammation of skin or irritation if contacted with skin or inhaled. Wear protective gear, including goggles, mask and gloves when handling this product. In case of accidental exposure, take the following emergency measures and seek appropriate medical attention:
1)In case of skin contact : Carefully wash entire area with soapy water, or take a shower if the exposed area is large, and seek medical attention.
2)In case of eye contact : Rinse with large volumes of clean water for at least 15 minutes, regardless of level of exposure, and seek immediate medical attention.
3)In case of inhalation : Move to a well-ventilated area, and seek medical attention. If breathing difficulties develop, provide artificial respiration or oxygen.
* Maximum permissible concentration in the air: 0.02 ppm.
