Method for production of polyurethane foams ru00cdgidas using crude glycerol not refined

摘要

This application relates to a method for the production of polyurethane foams ru00cdgidas using crude glycerol not refined.The polyurethane foams described here are obtained by reacting crude glycerol not refined, without any step of pre-treatment, separation or purification.With an isocyanate in the presence of a catalyst, a blowing agent and an agent tensioativo.The present application has application as thermal insulation material for construction, construction panels, refrigerators, freezers, tubes or pipes.
