Industrial filter cloth must be in a sealed place to prevent air and moisture absorption. The isocyanate and combined polyether drum should not be exposed to sunlight. It must be kept away from the heat source and placed in a cool and dry place. If the drum is placed upright, no water should be accumulated on the lid. If the whole barrel cannot be used up at one time, it is necessary to close the lid immediately after each use to prevent moisture and impurities from entering the barrel and affecting the quality. If more than two grades of polyether are used, they should be stacked and graded. The combination polyether added with ordinary flame retardant should not be stored for too long, and must be used on the same day of the day, otherwise it will easily cause deterioration and affect foaming quality.
