Title:
高誘電率および高破壊強度を有するカーボンブラック充填ポリウレタン
Document Type and Number:
Japanese Patent JP2010518200
Kind Code:
A
Abstract:
The invention provides polyurethanes filled with carbon black, which are characterised by a high dielectric constant and high breakdown strength, and which are synthesised from polyalkylene oxides that have been produced by DMC catalysis. The compositions comprise polyether polyurethanes which are the reaction products of one or more polyisocyanates and one or more polyol components, the polyol components being comprised of a) polyalkylene oxides produced by DMC catalysis, and b) 0-50 wt. % of polyols free from catalyst residues, and B) 0.1-30 wt. % of carbon black.
