Document Type and Number:
WIPO Patent Application WO/2018/124576
Kind Code:
A1
Abstract:
The present invention relates to a composition comprising: a linear alternating polyketone comprising carbon monoxide and at least one olefinically unsaturated hydrocarbon; talc; glass fiber; and the like, and a polyketone composition having excellent water fastness and mechanical property retention ratios, in comparison to brass and lead materials to be used for a water ball valve, can be developed and suitably applied to a water ball valve. In addition, a polyketone composition having excellent water fastness and mechanical property retention ratios, in comparison to a polyamide material to be conventionally used for a water pipe cap, can be developed and suitably applied to a water pipe cap.
