Abstract
The nanofillers: natural montmoryllonite (MMT) - Bentonite, natural MMT modified with a quaternary ammonium salt - Cloisite30B, has been used in rigid polyurethane foams (PUFs). The influence of fillers amounts on processing parameters, physical-mechanical properties (density, water absorption, brittleness and compression strength) and thermal properties (thermal stability, fire behaviours) of such foams has been analysed. The gel, cram and rise time for PUFs modified with nanofillers been observed during synthesis and has been elongated in comparison to unmodified foam. The thermal stability and water absorption of modified foams has been better compared with control foam.
