Product Code：SP104
Product Name：Methylphenyldichlorosilane
Product Introduction：
This product combines the structural characteristics of both methyl and phenyl groups. It features flexibility and ductility derived from methyl groups, as well as excellent heat and weather resistance endowed by phenyl groups. With moderate chemical reactivity, its hydrolysis and condensation reactions are easy to control. As an important organosilicon intermediate, it is used to synthesize modified phenyl silicone resins and specialty silicone oils, and also serves as a structure modifier for silicone rubber. It is widely applied in anti-aging and anti-corrosion coatings, electronic insulation and encapsulation, and polymer material modification, catering to fine chemicals, electrical protection and other industries.
