Hydrophobicity imparting particulate

摘要

A hydrophobicity imparting particulate is a hydrophobicity imparting particulate. 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) an 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 an 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.
