JZ)〗 The radiation crosslinking of PE

EVA

EPDM

EEA and their blends has been studied A non-halogen flame retardant polyolefin complex has been prepared with aluminum tri-hydrate （ATH） and red phosphor as flame retardant The experimental results show that radiation crosslinking can not only improve mechanical properties of the material but also increase its oxygen index （O I） thus the melt drop phenomenon disappears The new flame retardant polyolefin thus prepared

with a limiting oxygen index of 31

a tensile strength of 9 9MPa and an “elongation at break” of 200%

can therefore be applied to the electric wire and cable industry
