The Effect of New Flame Retardant Systems Containing Montmorillonite-Butyl Acrylate Nanoclay on the Flammability Properties of Polyuerethane Polymer

Abstract

The montmorillonite (MMT) was modified by butyl acrylate polymer. The newly modified MMT was characterized by TGA and DSC techniques. The modified MMT constitute melamine phosphate and different carbonizing agents and new flame retardant systems for poly urethane (PU) polymer. The flammability properties of the different PU formulations were characterized by cone calorimeter and ISO 1210 tests.The new flame retardant system gave the poly urethane polymer higher fire class, V0 (PU3 & 23). The thermal stability of the PU formulations was also improved.
