SANSIL™ MP-01 consists of approximately 100 nm spherical polymethylsilsesquioxane particles, featuring a three-dimensional network structure represented by (CH₃SiO_3/2)_n.
This structure exhibits a hybrid nature between inorganic and organic materials, with one methyl group bonded to each silicon atom.
As a result, SANSIL™ MP-01 offers lower specific gravity and greater flexibility compared to silica. Additionally, the particle surface is functionalized with trimethylsilyl groups, providing excellent hydrophobicity.
