POLYURETHANE RESIN COMPOSITION FOR ELECTRICAL INSULATION |
| 摘要 |
The invention provides a polyurethane resin composition for electrical insulation that has excellent compatibility between an isocyanate component and a polyol component, and that exhibits excellent heat resistance, moisture resistance, and insulation properties. The polyurethane resin composition for electrical insulation comprises (1) Part A comprising a polyisocyanate component obtained from at least one member selected from the group consisting of aliphatic diisocyanates and alicyclic diisocyanates, and containing one or more isocyanurate groups and one or more allophanate groups; and (2) Part B comprising a polyol component, wherein the polyisocyanate component has a molar ratio, (a)/(b), of isocyanurate groups (a) to allophanate groups (b) of 85/15 to 15/85. |

1. A polyurethane resin composition for electrical insulation comprising:
(1) Part A comprising a polyisocyanate component obtained from at least one member selected from the group consisting of aliphatic diisocyanates and alicyclic diisocyanates, and containing one or more isocyanurate groups and one or more allophanate groups; and (2) Part B comprising a polyol component, wherein the polyisocyanate component has a molar ratio, (a)/(b), of isocyanurate groups (a) to allophanate groups (b) in the range of 85/15 to 15/85. |
