Direct from our advanced DCS-controlled manufacturing lines, these four core products deliver high performance across polymer synthesis, automotive assembly, and chemical processing in Sofia, Plovdiv, and across Bulgaria.
Bulgaria's chemical manufacturing and material sciences sectors are undergoing a significant technological transformation. As a major logistics corridor linking Southeastern Europe to Western European consumer markets, Bulgaria has emerged as a regional center for plastic compounding, technical adhesives, electrical component manufacturing, and cosmetics packaging. Cyclosiloxanes and specialized organo-functional silanes serve as critical raw materials in this value chain.
Bulgaria's automotive parts manufacturing cluster relies heavily on Cross-Linked Polyethylene (XLPE) formulation. Organic silanes, including Vinyltrimethoxysilane (CAS 2768-02-7), provide essential moisture-crosslinking mechanisms, improving thermal resistance and mechanical properties in wiring insulation and structural automotive components.
As a global pioneer in rose oil production and high-value cosmetics formulation, the Bulgarian personal care industry increasingly demands high-purity cyclosiloxanes. These materials act as volatile carriers and sensory enhancers, enabling Bulgarian cosmetic brands to meet Western Europe's high performance standards.
Importing chemical materials into Bulgaria requires strict compliance with the European Chemicals Agency (ECHA). Our manufacturing processes are optimized to ensure low-impurity levels and proper registration, facilitating smooth customs clearance and regulatory safety compliance across the Balkan region.
Shandong Boctok Chemical Co. was founded in 2012 as a marketing and sales center for Boctok™ domestic and overseas businesses and achieved sales of US$280 million in 2023. The BOCTOK brand specializes in serving the Russian and Eastern European markets with high-tech silicone chemistry solutions.
Boctok has three main product categories, the first core business of organosilicone covers twelve series of silane coupling agents and crosslinkers, including aminosilane, methacrylate silane, epoxy silane, vinyl silane, mercaptosilane, alkyl silane, ethyl silicate, chlorosilane, silane isocyanates, phenyl silane, ureidosilane and serosilane.
Boctok also focuses on silicon oil, silicon resin, and silicon rubber, covering 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. They are widely used in glass fiber, electronics, wind energy, daily necessities, chemical industry, coatings, adhesives, XLPE electric cables, oil field drilling, textiles, rubber and molding to improve the quality and performance of applied products.
Boctok recently invested US$65 million to build a new manufacturing plant located in Bohai Industrial Park, a provincial chemical industry park in Shouguang City, Shandong Province. This facility expands our production chain of silane coupling agents, deploying 6 automatic DCS production lines with an annual output of 30,000 tons of silane coupling agents.
Boctok's Tier II core business is petroleum resins. We have invested in a key hydrocarbon resin manufacturer in China. We currently have three operating hydrocarbon resin factories located in Zibo, Fushun, and Nanjing. Taking advantage of reliable and abundant raw materials from SINOPEC and PetroChina, our advanced production facilities, and our decades of marketing experience, our products are widely used by customers, including many Fortune 500 companies.
These products include C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 hydrocarbon resins, C9 hydrocarbon resins, dicyclopentadiene, and methyl cyclopentadiene dimer. Boctok also focuses on the agrochemical industry, producing intermediates and raw materials for the production of pesticides, fungicides, insecticides, seed treatments, herbicides, and plant growth regulators.

Explore how our silane coupling agents, silicone resins, and petroleum resins support diverse industrial sectors.
Our organosilicone compounds, coupling agents, and specialty resins find applications across global and Bulgarian industries:
As EU environmental rules tighten regarding volatile cyclic compounds (D4, D5, and D6), our R&D roadmap focuses on next-generation silicone alternatives. By modifying cyclosiloxanes with low-VOC linear polymers and eco-friendly silane crosslinkers, we provide safe, high-performance chemical solutions for European industries.
1. Low-VOC Formulation Design: Restructuring traditional coupling agents to release less methanol and ethanol during curing, helping downstream users comply with strict indoor air safety regulations.
2. High-Purity Synthesis: Using gas chromatography and advanced distillation columns to lower trace impurities in cyclic siloxanes to less than 0.1% by weight.
3. Bio-Compatible and Renewable Intermediates: Investigating bio-derived alcohols for silane synthesis, reducing fossil carbon dependence in raw material supplies.
Explore our extensive range of high-performance silane coupling agents, resins, and specialty chemical products below.
Get authoritative answers to technical, regulatory, and logistics questions about sourcing cyclosiloxanes and silane coupling agents for European distribution.
Under EU REACH rules, cyclosiloxanes like Octamethylcyclotetrasiloxane (D4), Decamethylcyclopentasiloxane (D5), and Dodecamethylcyclohexasiloxane (D6) are identified as Substances of Very High Concern (SVHC) due to their PBT/vPvB profiles. Their use is restricted in wash-off cosmetics above 0.1% by weight. Boctok maintains compliance by offering low-impurity variants and alternative organo-functional linear silanes that help manufacturers meet regulatory limits without compromising performance.
Our recently upgraded Shouguang City facility utilizes automated Distributed Control Systems (DCS) and Safety Instrumented Systems (SIS). These systems monitor reactions in real time, controlling temperature, pressure, and raw material feed rates to keep variations between batches within narrow tolerances (less than 0.5% deviation in active content).
For Cross-Linked Polyethylene (XLPE) cable and hot water pipe production, Vinyltrimethoxysilane (CAS 2768-02-7) and Vinyltris(2-methoxyethoxy)silane (CAS 1067-53-4) are the industry standards. They introduce crosslinking sites into the polymer backbone, which improves temperature and moisture resistance in high-voltage and environmental applications.
We provide multiple shipping routes, including sea freight via the Port of Varna or Port of Burgas, and multimodal rail/road transport for inland cities like Sofia and Plovdiv. All shipments use certified dangerous goods containers (IBC totes, ISO tanks, or steel drums) accompanied by complete SDS, REACH documentation, and customs paperwork.
Yes. Our R&D and quality control teams can synthesize modified organosilicones, customize active ingredient ratios, and prepare specialized blends for applications like release agents, pressure-sensitive adhesives, and textile treatment agents.
