Samples of m-PPO (virgin and flame retarded) and high impact polystyrene blended with zinc and zinc borate (2ZnO·3B2O3·3.5H 2O), were pre pared. The effect of triaryl phosphate on the flame retardancy of PPO-HIPS in conjunction with zinc and zinc borate was studied. For polystyrene zinc borate shows some reduction in smoke generation. Zinc, however does not show any effect on smoke generation for high impact polystyrene. Triphenyl phosphate shows minimal flame retardancy in HIPS which is not enhanced by zinc. Addition of zinc gives an increase in oxygen index for FR m-PPO, whereas zinc borate decreases the OI values. Zinc borate may sequester triaryl phos phate and thus eliminate its vapor phase activity. Zinc borate shows a signifi cant reduction in smoke generation and rate of heat release for m-PPO.

Effective Role

This work aimed to use magnesium hydroxide (MH) as a flame retardant in poly(lactic acid) (PLA)/high impact polystyrene (HIPS)/wood flour (WF) composite. The 80/20/20 PLA/HIPS/WF composite was melt mixed with three loadings (20, 30 and 40 phr) of MH on a twin screw extruder, followed by an injection molding. The prepared wood-plastic composites (WPCs) were investigated for their impact strength (IS), tensile strength (TS), Young’s modulus (E), elongation at break (EB), flammability and morphology. The results showed that the 80/20/20 PLA/HIPS/WF composite exhibited higher IS, TS and E than the neat PLA, but at the expense of reducing the EB. It was also found that the WPCs filled with MH at all loadings provided much higher flame resistance and E over the neat PLA, HIPS, PLA/HIPS blend and PLA/HIPS/WF composite. Therefore, the MH could play an effective role as flame retardant in the WPCs.
