Stabilised polypropylene compsn. contg. absorbent inorganic filler - contains a synergic mixt. of an organic sulphur cpd. and an isocyanuric acid ester with hindered phenol gps. (BE 7.8.78)

摘要

A polypropylene compsn. contg. 19-85 wt. % adsorbent inorganic filler (I), 0.1-15 wt% organic S cpd. (II) which acts synergically with hindered phenolic antioxidant and 0.1-12 wt.% sterically hindered phenolic gp. contg. anti-oxidant (III) contains as (III) an isocyanuric acid ester. The stabilisation of polypropylene which is normally inhibited by (I) is improved by addition of (III). The compsn may be used in distributer heads, cam shaft housing, films, food packaging, car upholstery, flooring, roofing, doors etc.
