A hydrophobicity imparting particulate is provided in the present invention. A silicone composition comprises (A) a silicone polymer and (B) a hydrophobicity imparting particulate filler that imparts a hydrophobicity property to the composition. An insulator comprises a housing portion that includes a cured product of (A) a silicone polymer and (B) a hydrophobicity imparting particulate filler. A hydrophobicity recovery property of a silicone polymer composition can be improved by determining a target hydrophobicity recovery property for the cured silicone composition, selecting a hydrophobicity imparting particulate (HIP) to impart the hydrophobicity recovery property to the silicone polymer composition and compounding a blend of (A) a silicone polymer and (B) the selected inorganic filler and heating to cure the blend.
An insulator comprising a housing portion, said housing portion comprising a cured product composition of (A) a silicone polymer and (B) an hydrophobicity imparting particulate wherein said hydrophobicity imparting particulate imparts a hydrophobicity property to said composition;
An insulator comprising a housing portion, said housing portion comprising a cured product composition of (A) a silicone polymer and (B) two or more hydrophobicity imparting particulates comprising a mixture of calcium carbonate and magnesium carbonate or a mixture of magnesium silicate and calcium carbonate wherein said hydrophobicity imparting particulates impart a hydrophobicity property to said composition or an hydrophobicity imparting particulate that imparts a hydrophobicity property to said composition and a filler.
A method of improving a hydrophobicity recovery property of a silicone polymer composition, comprising:
