Direct from Shandong Boctok Chemical's High-Capacity DCS Controlled Manufacturing Plant
Founded in 2012, Shandong Boctok Chemical Co., Ltd. has established itself as an industry-leading player in the research, development, and supply of advanced organosilicone solutions and hydrocarbon resins. Centered as a premier marketing and sales hub for domestic and overseas businesses, Boctok achieved a record-breaking sales revenue of US$280 million in 2023. Over the years, the brand has demonstrated an exceptional ability to optimize supply chains for challenging markets, building specialized competence in serving highly demanding regions, including Russia, Eastern Europe, Central Asia, and the wider global distribution network.
Boctok’s core operations are divided into distinct chemical segments. The organosilicone business division is backed by strategic investments, state-of-the-art automation, and research facilities that cater to complex chemical matrices. This whitepaper analyzes the deep industrial capabilities of Boctok, highlighting the technological parameters, structural transformations, and high-performance applications of modified silicone oil and silane coupling systems. By aligning with Google's Search Quality Evaluator standards for Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T), we provide procurement teams with verified information gain to assist strategic raw material sourcing.
Boctok has invested US$65 million to build a state-of-the-art production plant situated in the Bohai Industrial Park in Shouguang City, Shandong Province. This specialized provincial chemical park hosts Boctok's high-tech manufacturing center, boasting 6 fully automated DCS production lines with an annual output capacity exceeding 30,000 tons of high-grade silane coupling agents.
By leveraging advanced distributed control systems (DCS) and high-integrity safety instrumented systems (SIS), Boctok ensures batch-to-batch consistency and minimizes standard deviations in viscosity, reactive purity, and volatile organic compound (VOC) emissions.
Unmodified dimethyl silicone oils lack reactive end-groups, limiting their cross-linking efficiency in paint, coatings, and composite materials. Chemical modification inserts functional side chains or terminal groups onto the polydimethylsiloxane (PDMS) backbone. This process enables key properties such as moisture curing, thermal stability, hydrophilicity, and organic compatibility.
By utilizing specific chemistry paths, Boctok introduces organo-functional modifications including amino, methacrylate, epoxy, vinyl, mercapto, alkyl, phenyl, and alkoxy groups. These modifications enable targeted reactivity with inorganic substrates (glass, metals, minerals) and organic polymers (epoxies, polyurethanes, rubbers).
Our range includes High-Hydrogen Silicone Oil, silanol silicone oil (OH polymer), vinyl silicone oil, and polyphenylmethyldimethylsiloxane. We also synthesize specialty resins like Methyl MQ resin and Vinyl VMQ resin, which serve as essential release agents, pressure-sensitive adhesives, and reinforcing agents.
By adjusting molecular weights, chain lengths, and functional group densities, Boctok produces modified silicone fluids customized for viscosity, thermal range, and emulsion stability, meeting the needs of global Tier-1 industrial buyers.
B2B procurement teams face key challenges when sourcing modified silicone oils and silane coupling agents from China. Achieving supply chain resilience requires balancing consistent quality, chemical purity, environmental compliance, and smooth customs processes.
In addition to organosilicones, Boctok operates two key supporting business units that build synergy across global industrial markets: **Hydrocarbon Resins** and **Agrochemical Intermediates**.
Boctok has invested in a key hydrocarbon resin manufacturer in China, operating three specialized factories in Zibo, Fushun, and Nanjing. Utilizing raw materials from SINOPEC and PetroChina, these factories produce:
These products are widely used by Fortune 500 companies in the adhesives, tire, paint, and varnish industries.
Boctok supports the global agricultural market by producing active ingredients, intermediates, and raw materials for:
Our organosilicone surfactants serve as key wetting agents and adjuvants, improving the spread and absorption of agrochemical formulations.
How modified silicone chemistry, hydrocarbon resins, and agricultural products integrate into global value chains.
At Boctok’s Shouguang City manufacturing site, production consistency is driven by strict quality management and process control.
Boctok utilizes centralized **Distributed Control Systems (DCS)** and **Safety Instrumented Systems (SIS)**. This automation closely regulates feed rates, reaction temperatures, and pressure levels. The system monitors parameters in real time, preventing thermal runaway and maintaining high batch consistency.
We implement ISO 9001 quality management standards throughout the production process. Every raw material shipment is tested before processing, and finished batches undergo testing (including FTIR, gas chromatography, and viscometry) to confirm compliance with technical specifications.
To protect the environment, our Shouguang plant is equipped with integrated wastewater treatment systems and VOC collection facilities. These systems handle gaseous emissions and process water, ensuring our operations align with global environmental standards.
The organosilicone industry is evolving to meet higher performance requirements and stricter environmental regulations. Boctok focuses on three key development paths for the next generation of modified silicone chemistry:
Traditional silicone coatings and textile agents can release volatile organic compounds and cyclic siloxanes (D4, D5, D6). Boctok is developing low-VOC alternatives and oligomeric silane structures to help downstream manufacturers meet strict environmental standards.
We are expanding research into hybrid molecules, such as silane-modified polyurethanes (SPUR) and polyether-modified silicones. These hybrid polymers offer the durability of silicones combined with the strength and paintability of organic resins.
With the growth of wind energy and electric vehicles, demand is rising for high-performance composites. We are optimizing our epoxy and amino-functional silane coupling agents to improve bonding at the interface of carbon fiber, glass fiber, and epoxy resins.
Exporting chemical materials globally requires strict compliance with international regulations. Boctok maintains dedicated regulatory support for all target markets:
