Abstract: Rigid polyurethane-polyisocyanurate (PUR-PIR) foams modified with tris(5-hydroxypentyl)-2-hydroxypropane-1,2,3-tricarboxylate (THHT) were synthesized. Selected foams were subjected to degradation in an aging oven for 168, 346, and 504 h, respectively. These foams have been exposed to UV radiation.… read more here.

Abstract: This article describes the results of multidirectional research on the flammability and heat properties of rigid polyurethane–polyisocyanurate foams (PUR–PIR). They were produced, using new three polyols (citrates) obtained from 2-hydroxypropane-1.2.3-tricarboxylic acid (citric) and selected diols:… read more here.
