Sibond is a time-honored professional manufacturer of phenylsilane in China with profound technical expertise and leading production scale. Formerly the state-owned Dalian Yuanyong Organosilicon Plant founded in 1984, the company has been deeply engaged in the organosilicon industry for more than four decades. It is one of the earliest domestic enterprises dedicated to the R&D and industrial production of phenylsilane, and has long led the technological development and industry standards of the sector. After years of development and industrial upgrading, the company has established two modern production bases: Liaoning Sibond New Materials Co., Ltd. and Jiangxi Fort Chemical New Materials Co., Ltd. With a rational industrial layout and robust production capacity, its overall scale ranks among the top in China’s phenyl organosilicon industry. Adopting two mature and advanced core processes—the direct method and thermal condensation method—the company specializes in the production of basic phenylchlorosilane monomers, including phenyltrichlorosilane, diphenyldichlorosilane and methylphenyldichlorosilane. Through refined synthesis via alcoholysis and hydrolysis, it further manufactures high-end phenyl intermediates such as phenyltrimethoxysilane, diphenyldimethoxysilane, methylphenyldimethoxysilane, diphenylsilanediol and octaphenylcyclotetrasiloxane. Extending further down the industrial chain, it also mass-produces phenyl organosilicon polymer new materials, including methylphenyl silicone oil, methylphenyl silicone resin and methylphenyl silicone rubber. Endowed with a profound historical heritage, solid technological accumulation, large-scale production advantages and consistently reliable product quality, the company’s products are widely applied in key fields such as national defense and military industry, aerospace, electronics and electrical engineering, cosmetics, construction, textiles and medical care. It stands as a benchmark enterprise in China’s phenyl organosilicon material industry with outstanding strengths in history, professionalism and production scale.
