| Cosmonate PM-27 |
 |
Cosmonate PM-27 is used in reducing various noise that arise from vehicle engine, road and tires. It is a special modified MDI that is composed of sound suction and echelon materials. Cosmonate PM-27 is liquefied product in normal temperature and is most stable when stored under freezing conditions and also could be handled the best. When in solvent-free form, it is mixed with 4,4-diphenylmethane diisocyante MDI monomer. When these are mixed with high resolution oligomer that is of dimer, trimer, and tetramer, it becomes a product that has up to maximum viscosity of 140cps(25'C).
Cosmonate PM-27 special modified MDI used to produce soft polyurethane foam as noise suction medium for car noise suction, theater and buildings as musical hall. Due to its superior ventilation feature, it has high noise suction effect, excellent flow and molding property that is advantageous in making complicated mold. |
