PURPOSE:To suppress the increase of viscosity of a composition to lower the load applied to a molding apparatus by adding at least 200wt.% of an inorganic filler to 100 pts.wt. of polymer. CONSTITUTION:A cable is prepared using halogen-free materials for all of the insulated wires 1, the intermediate filler 4, and a sheath 5. The filler consists of halogen-free polymer having melt index at least 30 and an inorganic filler with grain size at least 5mum in a ratio of 100 pts.wt. and at least 200 pts.wt., respectively. The viscosity of the composition is suppressed and thus the load applied to a molding apparatus is lowered by adding the inorganic filler at so high ratio as at least 200wt.% and using the polymer having melt index(MI) at least 30. Moreover, the flame-resistant wire.cable is halogen-free and scarcely generates smokes and the filler having handling easiness at the time of terminal processing is applied to the halogen-free and flame-resistant cable. |
