ONE COMPONENT ISOCYANATE PREPOLYMER MIXTURE FOR POLYURETHANE PRODUCT FORMULATION IN A SINGLE STEP PROCESS

摘要

The subject of the invention is a one component isocyanate prepolymer mixture for formulating a polyurethane product in a single step process, with monomeric methylene diphenyl diisocyanate (MDI) content in the said mixture not exceeding 3%, preferably less than 2%, more preferably less than 1% of the total weight, containing: - monofunctional alcohol, - isocyanate component or isocyanate mixture component, - propellant, - catalyst, - stabiliser, - one or more polyols, characteristic in that the monofunctional alcohol constitutes ethylene glycol ethers or propylene glycol ethers and a method for formulating one component polyurethane foam made on the basis of the mixture.
