Abstract: The ethylene vinyl-acetate copolymer (EVM) rubber/magnesium hydroxide (MH) blend was crosslinked by Co-60 irradiation in the presence of trimethylolpropane triacrylate. And the effects of gamma irradiation on the properties of irradiated EVM/MH blend were investigated through the measurements of the gel content, Vicat point, limiting oxygen index, UL-94, tensile properties, X-ray diffraction and thermogravimetric analysis. The test results show that the thermal, mechanical and flame-retardant properties of the EVM/MH blend all are markedly improved by Co-60 irradiation. (C) 2003 Elsevier Ltd. All rights reserved.
