Effect of Cell Opener on Cell-opening Property of Slow Resilience PU Foams and Comparison of Detection Methods
The cell opener KY1216,BDM-5 and 1900H were applied to the slow resilience polyurethane(PU)foam with different dosage,and the cell-opening properties of different samples were tested by traditional bubble method(TBM),breathable meter method(BM)and bubble collapse drop method(BCDM).The results showed that BCDM had the advantages of intuitive data,accurate judgement,convenient and fast and low lost,which improved the detection efficiency of cell opener,and was worthy of being promoted and applied as an efficient detection method for slow resilience cell opener.
