| 摘 要： | Effect of tri（2-hydroxypropyl）, tri（2-hydroxybutyl）and tri（hydroxythiodiethylene） borates （BT2HB, BT2HP and BTHET） on the thermal and heat properties of the rigid polyurethane-polyisocyanurate （PUR-PIR） foams was investigated： Increasing amounts of BT2HB and BT2HP in the foam composition, from 0.05 to 0.4 of chemical equivalent, caused increases in the softening point, the temperature of the first mass loss, the extrapolated tempera- ture of the main mass loss foam and temperature of the highest rate of the mass loss. In the case when BTHTE was added to the foam compositions, the lower increase in the mentioned above characteristic temperatures was observed as compared to those of standard foam （without borate added）.
