Abstract
Flowable, pressure-compensating material compositions are provided. The compositions are directed toward improving one or more aspects of the flowable material, such as by providing/improving flame retardancy and/or the homogeneity of the composition over time. For instance, one composition includes a liquid, a viscosity-increasing material, and beads having a preselected coating thereon to provide for a coupling interaction with at least one of the liquid and the viscosity-increasing material.
Claims19
A flowable, pressure-compensating composition comprising:
- silicone oil;
- and
- substantially spherical and hollow particles having a diameter of less than about 300 micrometers, wherein said silicone oil is present in an amount whereby said particles are suspended within said silicone oil;
- wherein said composition is characterized by being a viscous, flowable, and pressure-compensating material, having a substantially homogeneous consistency, flowing in response to continuously applied pressure and being resistant to flow in response to instantaneously applied pressure.
A flowable, pressure-compensating composition, as claimed in claimed 1, wherein said silicone oil is present in an amount ranging from about 50 weight percent to about 74 weight percent based on the total composition weight.
Dependencies are inferred from the claim text.
