POLYMER POLYOL FOR URETHANE RESIN SEALING MATERIAL OF MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a polymer polyol for urethane resin sealing material of membrane module, capable of providing a sealing material excellent in heat resistance and oxidation stability and having a low calorific value.

SOLUTION: The polymer polyol is formed by dispersing polymer particles (p) in polyol dispersion medium (b). The polymer polyol for urethane resin sealing material of membrane module includes polyol dispersion medium (b) containing castor oil and/or castor oil derivative (a). There are also a urethane resin-forming composition using the same and sealing material for membrane module formed by hardening the composition.
