产品介绍
Product Introduction
BOH 8507是一种新型的低气味、低VOC的聚醚多元醇，单纯使用BOH 8507生产海绵时，能使海绵的断裂伸长率达到400%以上；当BOH 8507与普通聚醚多元醇配合使用时，在保持海绵的支撑强度、回弹性的情况下，海绵的拉伸强度和撕裂强度均能得到有效的提高。
BOH 8507 is a novel low-odor, low-VOC polyether polyol. When sponge is produced with BOH 8507 alone, the elongation at break of the sponge can reach over 400%. When BOH 8507 is used in combination with ordinary polyether polyols, the tensile strength and tear strength of the sponge are effectively improved while its support property and resilience are maintained.
