Fire resistant resin composition and electrical wire having a covering formed of the composition

摘要

A fire resistant resin composition, for the covering of an electrical wire has the synthetic resin components: (a) 60 to 97 parts by weight of a propylene resin containing propylene as its main monomer component by weight, and (b) 3 to 40 parts by weight of a styrene-based thermoplastic elastomeric resin modified with an unsaturated carboxylic acid or a derivative thereof, components (a) and (b) being free of halogen and the total amount of components (a) and (b) being 100 parts by weight and there being no other synthetic resin components included in the composition. The composition further contains: (c) 30 to 200 parts by weight of fire resistant metal hydroxide per 100 parts by weight of components (a) and (b).
