In order to find an effective halogen-free flame retardant for acrylonitrile-butadienestyrene copolymer (ABS), organo-phosphorus compounds were studied and their flame retarding performances were determined by UL 94 vertical test. It is found that the flame retardancy strongly depends on phosphorus (P) content of organophosphorus compounds. Only the mixture of ABS with 2-(6-oxido-6Hdibenz< c,e><1,2>oxaphosphorin-6-yl) methyl diethyl phosphinate (ODOPM-DE), which has the highest P content, i.e., 17.68 % gives V-0 rating for the 70/30 composition.

Halloysite nanotubes (HNTs) and intumescent flame retardant (IFR)-filled 80/20 (wt/wt) polypropylene/acrylonitrile–butadiene–styrene (PP/ABS) blend and their composites in the presence of dual compatibilizer have been prepared using twin screw extruder followed by injection molding. There exists the formation of α- and β-form of PP crystals in addition to enhancement in crystallinity of PP phase by an addition of HNTs and IFR in 80/20 (wt/wt) PP/ABS blend and their composites in the presence of dual compatibilizer. In addition, scanning electron microscopy (SEM) reveals the formation of matrix-droplet morphology, and the dispersion of HNTs and IFR in 80/20 (wt/wt) PP/ABS blend and its composites in the presence of dual compatibilizer results in a refinement in matrix-droplet morphology. This has resulted in an enhancement in tensile and impact properties of HNTs- and IFR-filled 80/20 (wt/wt) PP/ABS blend and their composites in the presence of dual compatibilizer. Thermal stability also increases by an addition of HNTs and IFR in 80/20 (wt/wt) PP/ABS blend and their composites in the presence of dual compatibilizer due to formation of intumescent char.

For achieving sufficient flame retardancy, high magnesim hydroxide (MH) content is needed in MH flame retardant Acrylonitrile-butadiene-styrene copolymer (ABS) composites (ABS/MH), which will cause a great decrease in mechanical property and difficulty in preparing samples for measurement. We prepared ABS/MH filled high 60.0% flame retardant by compounding ABS and modified flame retardant MH, fumed silica (SiO2) and zinc borate (ZB) via TX-10 phosphate/polyacrylate latex and studied the effect of a small amount of SiO2 and ZB with MH in ABS for improving the thermal decomposition of ABS/MH. The thermal stability of the modified flame retardant could meet the processing temperature of ABS. The incorporation of ZB, SiO2 or SiO2/ZB could improve the thermal stability of ABS/MH.

Abstract A thorough study was carried out to investigate the priority of a novel co-rotating non-twin screw extruder (NTSE) over a traditional twin screw extruder (TSE) in the mixing process of halogen-free intumescent flame-retardant acrylonitrile-butadiene-styrene (ABS) composites. The homogeneity of the flame-retardant additives of the composites processed by NTSE and TSE under the same operating conditions was characterized by using mechanical performance properties, limiting oxygen index values, UL-94 tests, and thermogravimetric analysis. All the results suggested that NTSE could achieve better mixing of the flame-retardant additives in the polymer matrix than TSE, which was further clarified by the scanning electron microscope pictures.
