USE OF AQUEOUS POLYURETHANE HOT SOFT FOAM STABILIZING SOLUTIONS OF LOW VISCOSITY HAVING POLYETHER SILOXANE IN THE PRODUCTION OF POLYURETHANE HOT SOFT FOAMS

摘要

The subject matter of the present invention relates to a low-viscosity aqueous hot-cure flexible polyurethane foam stabilizer solution which can be used in the production of hot-cure flexible polyurethane foams, wherein the low-viscosity aqueous hot-cure flexible polyurethane foam stabilizer solution comprises the following components: 40% to 70% by weight of polyethersiloxane, 0.5% to 20% by weight of organic surfactant, 10% by weight of water, 0% by weight of organic solvent additions, in which the polyethersiloxane has the following formula (I) R1Si(CH3)2O[Si(CH3)(OSi(CH3)2R0)O]u[Si(OSi(CH3)2R0)2O]v[Si(CH3)2O]w[SiCH3R2O]x[SiCH3R3O]y[SiCH3R4O]z[SiR3R4O]tSi(CH3)2R5 (I).
