SILICONE RUBBER CLAY COMPOSITION

摘要

PURPOSE:To obtain the subject composition capable of floating on water because of its specific gravity of <=1.0 and having an enjoyable structure by floating thereof in a water tank or bathtub, free from offensive small and capable of coloring into proper color and being excellent in safety and hygiene. CONSTITUTION:A silicone rubber clay composition having <=1.0 specific gravity and obtained by blending (A) 100 pts.wt. orgranopolysiloxane mixture obtained by blending A1: an organopoly-siloxane expressed by formula I [R is (substituted) monovalent hydrocarbon group; (a) is 1.85-2.10] having 5000-200000 cst viscosity with A2: an organopolysiloxane also expressed by formula I but having >=1000000 cst viscosity at a weight ratio of 80:20 to 40:60 with (B) 20-80 pts.wt. inorganic filler (e.g. quartz fine powder or diatomaceous earth) having average particle diameter of 1-50mum, preferably 0.5-30mum and (C) 20-80 pts.wt. glass balloon having <=200mum average diameter and 0.2-0.8/cc average particle density.
