摘要：
A composition comprising
(a1) a polyether polyol,
(a2) a polyolefin polyol and
(a3) a polyester polyol obtainable by epoxidation of an unsaturated fatty acid ester and subsequent ring-opening reaction with a compound containing active hydrogen,
can be used for the preparation of PUR foam which distinguishes by low-temperature flexibility and low dielectric loss and is suitable for filling the gap between the condenser core and the outer composite or porcelain insulator in the manufacture of resin impregnated paper (RIP) bushings.
