Abstract
The invention provides polyisocyanurate systems for manufacture of polyisocyanurate foam components such as those from SRIM processes. The reaction systems include a polyisocyanate and a polyisocyanate reactive component that includes a trimerization catalyst, polyol, and a carboxylic acid blowing agent, optionally with water as a co-blowing agent. The reaction systems can be blown exclusively with carboxylic acid to produce SRIM products which can be demolded with reduced mold residence time.
