| 摘要 |
A composition suitable as a buoyant putty is disclosed, which is a mixture o f a discontinuous solid phase of microballoons, and a viscous liquid continuous phase comprising a polydimethylsiloxane; the polydimethylsiloxane of the continuous phase has a viscosity betweeen 100,000 cs and 2,000,000 cs; the viscosity of the polydimethylsiloxane of the continuous phase is achieved by incorporating polydimethylsiloxane molecules of sufficiently high molecular weight; containment within other materials is optional; additional dyes, pigments particles fibers, felts or fabrics can confer additional visibility , strength, stiffness, dryness or friction; accompanying properties of malleability, and thermal, electrical, vibratory, shock and acoustical insulation, also make this composition useful for other applications that require such qualities.
