DOI: 10.1002/adv.21631
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.
