The castor oil fatty acid contains 90% castor acid (9-alkenyl-12-hydroxyoctadecanoic acid) with a j-hydroxyl value of 163mgKOH/g, a hydroxyl content of 4.94%, a molecular weight of 345 calculated by hydroxyl. Calculated by hydroxyl, the castor oil contains 70% trifunctionality and 30% bifunctionality, and the average hydroxyl functionality is 2.7. The polyurethane adhesive made from castor oil has good low temperature performance, hydrolysis resistance and electrical insulation.
