By engineering advanced polymers and maintaining highly reliable chemical profiles, Boctok provides premium solutions in 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.
Continuous investment in process automation, environmental protection, and safety instrumented systems at our Shandong production facilities.
In modern industrial engineering, linear silicone fluids (primarily polydimethylsiloxanes, or PDMS) serve as the foundation of countless high-performance applications. Because of their unique siloxane backbone (Si-O-Si bonds), these fluids exhibit properties that organic polymers cannot replicate: exceptional thermal stability across a broad temperature range (-50°C to +200°C), low surface tension, excellent dielectric properties, high shear resistance, and chemically inert behavior. As a leading manufacturer from China, Boctok provides tailored viscosities ranging from ultra-low viscosity fluids for heat-exchange media to high-viscosity gums used in specialized damping systems.
Our macro solutions focus on resolving the pain points of thermal management and environmental degradation. In the electronics sector, the push toward high-power density components demands linear silicone fluids that exhibit minimal volatile organic compounds (VOCs) to prevent contact failure. Boctok's vacuum-rectified silicone fluids ensure low outgassing, meeting the strict requirements of automotive sensor housings and semiconductor packaging. Similarly, in heavy-duty machinery, our fluids are used to formulate high-performance lubricants that resist breakdown under extreme mechanical loads, minimizing operational downtime for international enterprises.
The global demand for high-performance organic silicones is experiencing a structural shift toward sustainable, vertically integrated supply chains. Currently, China stands as the primary producer of silicone metal and crude silicone monomers, providing unprecedented raw material stability. Boctok has capitalized on this domestic chemical integration. By securing stable supply chains from domestic giants like SINOPEC and PetroChina for our petroleum resin line and utilizing our proprietary, state-of-the-art silane manufacturing sites, we guarantee structural cost-efficiencies and reliable shipment schedules for global B2B buyers.
This industrial dominance is reflected in our recent major investments. Boctok invested US$65 million to build a modern, large-scale plant in the Bohai Industrial Park in Shouguang City, Shandong Province. This provincial chemical park is designed to sustain hazardous process safety and ensure strict environmental compliance. The new plant features 6 fully automated DCS production lines dedicated to silane coupling agents and advanced crosslinkers, achieving an annual output capacity of 30,000 tons. By implementing high-throughput automation and safety systems, we deliver uniform product quality that satisfies the stringent quality requirements of Fortune 500 chemical distributors and end-use manufacturers alike.

Explore our structured technical solutions catering to chemical, electrical, construction, and consumer industries.
The organic silicone industry is transitioning from basic commodity supply to high-precision, low-carbon engineering. As environmental policies tighten globally, the demand for eco-friendly silane systems and linear silicone fluids with low molecular weight cyclics (D4, D5, D6 under 0.1%) is rising. Boctok's technical roadmap focuses heavily on developing "high-purity, zero-VOC" linear silicone fluids. By upgrading our polymer stripping towers and integrating automated fractionating steps, we aim to meet the strict REACH criteria enforced in the European Union and the dynamic regulatory demands of APAC markets.
In addition, our research division is actively exploring bio-based organosilicone paths. This includes sourcing bio-ethanol as the feed base for our ethoxy-silanes and integrating circular carbon metrics into our production loops. Over the next decade, we project that the development of specialized silane coupling agents will focus on hybrid cross-linking mechanisms that work with recycled rubbers and bioplastics. This development path ensures that our partners in the automotive and packaging industries can achieve their circular economy targets without compromising on mechanical shear strength or durability.
Operating a chemical export business of US$280 million demands rigorous adherence to regional environmental and logistical safety standards. At Boctok, our dedicated regulatory compliance team ensures that all shipments of silanes, petroleum resins, and silicone rubbers are fully compliant with RoHS, REACH, and GHS labeling standards. We provide comprehensive Safety Data Sheets (SDS) in multiple languages (including English, Russian, German, and Spanish) to guarantee seamless customs clearance and safe storage operations for our overseas clients.
Our localized support network is designed to address technical queries within 24 hours. Because silicone oil performance is highly dependent on formulation dynamics (such as emulsifier matching, dilution ratios, and curing temperatures), our field service engineers work directly with your processing teams. Whether you are adjusting the viscosity of a heat-transfer system in Northern Europe, developing a durable textile softener in Southeast Asia, or applying C5 hydrocarbon resins to road marking paint in Russia, Boctok provides tailored, localized application advice and chemical validation services.
Get answers to the most common questions regarding chemical properties, shipping logistics, and custom compounding options.
We supply linear silicone fluids (polydimethylsiloxane / dimethicone) in a wide viscosity range, starting from ultra-low viscosity (0.65 cSt to 5 cSt) for special coatings and heat transfer, up to mid-to-high ranges (100 cSt to 60,000 cSt) for mechanical lubrication, damping, and cosmetic bases, and up to ultra-high viscosity gums for rubber compounding.
Silane coupling agents act as molecular bridges between inorganic substrates (such as silica, glass fibers, or metals) and organic polymers (such as epoxy, polyurethane, or natural rubber). This chemical bridging improves dispersion, increases structural adhesion, and elevates thermal stability and water resistance in the finished compound.
We source high-purity C5 and C9 feedstocks directly from SINOPEC and PetroChina. These feedstocks are polymerized and hydrogenated using advanced catalytic systems at our plants in Zibo, Fushun, and Nanjing, ensuring exceptional clarity, low odor, and high compatibility with rubber polymers.
For standard product lines, our optimized logistics system processes orders within 7 to 14 working days. Custom formulations or specialty viscosity silicone oils require additional quality validation, taking approximately 21 to 30 days. We coordinate closely with major shipping lines to ensure timely delivery to European, Russian, Asian, and American ports.
A diverse selection of raw materials, functional additives, and agricultural intermediates certified for international performance standards.
