NON-COMBUSTIBLE POLYESTERPOLYOL AND/OR POLYETHERPOLYOL PREBLEND FOR PRODUCING FOAMED PRODUCTS

摘要

The invention relates to flameproof polyetherpolyol and/or polyesterpolyol preblends for producing foamed products, in particular PU foam products. Said preblend consists of polyol, more than 4 wt % of a binary expanding agent mixture of HFC 365mfc and an additional fluorocarbon and between 10 and 20 wt % of a phosphor-based flameproofing agent.
