Abstract:
A high resilience cold-cure foam, comprising the reaction product of:a) an isocyanate component comprising a mixture of TDI and MDI in the weight ratio of 95:5 to 60:40, with b) one or more dispersions of polymers comprising relatively high molecular weight hydroxyl compounds which comprise the reaction product of: (i) one or more mono- and/or polyisocyanates, with (ii) at least one compound having primary and/or secondary amino groups, said compound being selected from the group consisting of polyamines, hydrazines, hydrazides and alkanolamines, â€ƒin a polyether having 1 to 8 primary and/or secondary hydroxyl groups with a number-average molecular weight from 400 to 16,000, in the presence of c) one or more chemical and/or physical blowing agents, â€ƒand, optionally, one or more of: d) one or more flame retardants which are liquid and/or soluble in a), b) or c), e) one or more compounds with at least two hydrogen atoms which are reactive towards isocyanates and with a molecular weight from 32 to 399, and f) further auxiliaries.
