Abstract
The microporous polyurethane elastomer composition material suitable for insole consists of one component A and one component B in the weight ratio of 100 to 60-80. The component A consists of polyether polyol, polymer polyol, cross-linking agent, foam stabilizer, foaming agent and catalyst; and the component B is pre-polymer of polyether polyol and isocyanate. When it is used, the two components are mixed in the said weight ratio at normal temperature to form microporous polyurethane elastomer. The normal temperature production process of insole is simple and has easy operation, no waste, stable product quality and low production cost.
