Effect of tri[(3-chloro-2-hydroxy-1-propoxy)-1-butene]borate on the functional

properties of rigid polyurethane-polyisocyanurate foams

Polimery 2004, No 3, 187



DOI: dx.doi.org/10.14314/polimery.2004.187


Summary

Tri[(3-chloro-2-hydroxy-1-propoxy)-1-butylene] borate (TChHPB) was obtained as a result of reaction of tri(hydroxybutylene) borate with epichlorohydrin. It was applied in a synthesis of rigid polyurethane-polyisocyanurate (PUR-PIR) foams, as a flame retardant and an agent improving other functional properties. Increase in TChHPB content resulted in reduction of flammability which in turn was demonstrated by increase in combustion residue (Psp), oxygen index (OI) and compressive strength (σM). There was no observed effect of TChHPB on the dimensions and shapes of the pores of the foams.


Keywords: rigid PUR-PIR foams, tri[(3-chloro-2-hydroxy-1-propoxy)-1-butylene] borate, fire retardancy, functional properties
