产品介绍
Product Introduction
BOH 90139是高效含有复合抗氧剂的配方，主要用于聚醚型海绵，聚酯型海绵的生产中，可显著减轻海绵在加工过程中，储存过程中和使用过程中发生的黄变现象，可显著抵抗海绵中发生的老化，黄变，力学性能损失等。
BOH 90139 is a highly efficient formula containing compound antioxidants, mainly used in the production of polyether-type and polyester-type sponges. It significantly reduces the yellowing of the sponge during processing, storage and use, and effectively resists the aging, yellowing and loss of mechanical properties of the sponge.
BOH 90139同时抵抗热压工艺和自然光。BOH 90139的添加量在1-6%的范围内，可以起到期待的使用效果。
BOH 90139 also resists the heat-pressing process and natural light. The dosage of BOH 90139 is in the range of 1-6%, which achieves the expected effect.
BOH 90139应该配合全反应型胺催化剂使用。
BOH 90139 should be used together with a fully reactive amine catalyst.
