Expandable mixtures that are devoid of isocyanates
摘要:
Foamable mixtures of excellent quality and which are isocyanate free are prepared from silane-terminated prepolymers in which a proportion of the silane end groups are replaced by non-polar organic groups. As a result, the prepolymers have much greater hydrocarbon blowing agent compatibility.
