性能及用途： 
 四甲基環(huán)四硅氧烷相對(duì)于線形聚甲基氫硅氧烷來講，雜質(zhì)少，純度高，鏈節(jié)固定，易于改性分子的設(shè)計(jì)，可用于制備各種特定含氫量和所需鏈節(jié)數(shù)的甲基氫硅氧烷及改性硅氧烷。如：用于制備高含氫量的含氫硅油；制備高溫*化硅橡膠、加成型液體硅橡膠的交聯(lián)劑；合成側(cè)鏈聚硅氧烷液晶高分子，及各種高純度的側(cè)鏈改性硅油。如：長(zhǎng)鏈烷基硅油；聚醚硅油；環(huán)氧硅油；羧基硅油；氨基硅油等。 
還是光電材料的優(yōu)良浸漬劑。 
包裝及貯存： 
200kg內(nèi)涂桶，50kg、25kg塑料桶包裝。 
 產(chǎn)品密封包裝貯于陰涼干燥處，避免與酸、堿接觸，并遠(yuǎn)離火源
