Polyisocyanurate systems, pultrusion of those systems to produce reinforced polyisocyanurate matrix composites, and to composites produced thereby. The polyisocyanurate systems include a polyol component, an optional chain extender, and an isocyanate. The polyisocyanurate systems have extended initiation times of about 5 minutes to about 30 minutes at room temperature, and can be snap cured.

Polyisocyanurate compositions and composites

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.
