Shandong Boctok Chemical Co. was founded in 2012 as a marketing and sales center for Boctok™ domestic and overseas businesses. Demonstrating consistent growth and deep integration within the industrial chemical value chain, the company achieved sales of US$280 million in 2023. The BOCTOK brand specializes in serving the Russian market, providing custom logistics, rigorous chemical conformity compliance, and tailored product parameters to match severe climate demands and heavy industrial standards.
Boctok operates across three main product categories. Our primary core business focuses on organosilicone materials, covering twelve series of silane coupling agents and crosslinkers. These include: aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane, and serosilane. Additionally, Boctok is a prominent developer of premium silicone oil, silicone resin, and silicone rubber derivatives. This wide-ranging portfolio comprises high-hydrogen silicone oil, dimethicone, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil and OH polymer, alkoxy silicone oil, methyl MQ resin, vinyl VMQ resin, room-temperature vulcanized methyl silicone rubber, 110 methyl vinyl silicone rubber, and 120 methyl phenyl rubber.
These advanced structural elements and polymer matrices are widely used in glass fiber, electronics, wind energy, daily necessities, chemical processing, high-performance coatings, structural adhesives, XLPE electric cables, hot water pipes, oil field drilling, textiles, rubber compounding, and industrial molding to improve the quality, durability, and shear resistance of end products.
Polydimethylsiloxane (PDMS), commonly known as dimethicone, represents the most widely utilized silicon-based organic polymer. Formed by a repeating inorganic backbone of silicon and oxygen (Si-O-Si) with organic methyl groups attached to the silicon atoms, PDMS is characterized by its high shear stability, biological inertness, low chemical reactivity, excellent dielectric properties, and outstanding resistance to extreme temperatures, UV exposure, and weathering.
Information Gain: The Chemistry of Performance. The unique bond angle of the siloxane chain (~143°) coupled with a low rotation energy around the Si-O bond gives PDMS its extraordinary flexibility and low glass transition temperature (-125 °C). This molecular configuration yields highly predictable viscosity characteristics, which are crucial for engineering applications requiring high-precision dampening or exact molecular delivery.
In recent years, the global PDMS market has entered a phase of advanced diversification. Key industrial developments include:
Beyond our organosilicone portfolio, Boctok's Tier II core business encompasses high-grade petroleum resins. Having invested in a key hydrocarbon resin manufacturer in China, we operate three advanced factories located strategically in Zibo, Fushun, and Nanjing. Leveraging reliable, raw material streams directly from petrochemical leaders SINOPEC and PetroChina, our advanced manufacturing sites produce superior hydrocarbon resins widely utilized by Fortune 500 companies globally. These include C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 hydrocarbon resins, C9 hydrocarbon resins, dicyclopentadiene (DCPD), and methyl cyclopentadiene dimer.
Furthermore, Boctok acts as a critical supplier in the agrochemical industry, synthesis intermediates, and raw materials for the production of crop protection products. Our agricultural line includes raw materials for pesticides, fungicides, insecticides, seed treatments, herbicides, and plant growth regulators designed to optimize yield and environmental resilience.
Procuring raw organosilicone chemicals requires more than standard vendor selection; it demands absolute supply chain reliability, quality consistency, and cost-effective scaling. Global procurement teams face significant pressure to secure materials that satisfy tight viscosity tolerances, strict purity levels, and predictable lead times amid fluctuating international logistics.
To address these structural needs, Boctok invested US$65 million to construct a state-of-the-art chemical manufacturing facility located in the Bohai Industrial Park, a provincial-level chemical industry park in Shouguang City, Shandong Province. This facility expands our production chain of silane coupling agents, incorporating 6 automatic DCS production lines with an annual capacity of 30,000 tons.
