Founded in 2012, Shandong Boctok Chemical Co. has rapidly grown to establish itself as a premier marketing, sales, and technical service hub for domestic and global operations. In 2023, the enterprise reached an exceptional sales milestone of US$280 million, affirming its market authority and solid financial foundation. While serving global clients, the specialized BOCTOK™ brand has acquired dominant traction in the Russian and Eastern European chemical distribution networks.
Boctok's product portfolio is meticulously structured into three primary chemical families. The crown jewel is our organosilicone division, consisting of twelve comprehensive series of silane coupling agents and crosslinkers. These comprise key chemical solutions including amino silanes, methacrylate silanes, epoxy silanes, vinyl silanes, mercaptosilanes, alkyl silanes, ethyl silicates, chlorosilanes, silane isocyanates, phenyl silanes, ureidosilanes, and serosilanes.
Beyond basic silane coupling matrices, we maintain advanced processing operations dedicated to downstream silicone products, including high-hydrogen silicone oil, dimethicone, vinyl silicone oil, polyphenylmethyldimethylsiloxane, phenyl silicone oil, silanol silicone oil, OH polymer, alkoxy silicone oil, methyl MQ resin, vinyl VMQ resin, and various specialized rubbers like room-temperature vulcanized methyl silicone rubber and 110/120 methyl phenyl rubbers.
Amino silane coupling agents are vital dual-functional molecular agents designed to bridge the gap between inorganic mineral substrates (such as glass fibers, silica, talc, and metal oxides) and organic thermoplastic or thermosetting polymer matrices. By possessing both a hydrolyzable alkoxy group (typically methoxy or ethoxy) and an organic functional amino group (primary, secondary, or tertiary amines), amino silanes act as structural chemical links that modify interfacial properties.
When incorporated into plastic raw materials, such as polyamides (PA6, PA66), polybutylene terephthalate (PBT), polypropylene (PP), and polyethylene (PE), amino silanes significantly improve the mechanical stress distribution, tensile strength, and impact resistance. The chemical interaction proceeds through a two-stage reaction:
The alkoxy silane groups undergo rapid hydrolysis in the presence of trace moisture, forming active silanol (Si-OH) groups. This stage is crucial for initiating bonding to inorganic hydroxyl-rich filler surfaces.
Silanols condense on the substrate surface, establishing stable covalent metalloxane (Si-O-M) bonds. Simultaneously, the hydrophobic tails align toward the organic matrix, reducing interfacial moisture aggregation.
The organofunctional amino group (e.g., in 3-aminopropyltrimethoxysilane) chemically reacts or interdiffuses within the polymer resin. This creates a highly resilient interpenetrating network at the interface.
Boctok's Tier II core operation centers around premium hydrocarbon petroleum resins. By establishing close partnerships with leading hydrocarbon resin refineries in China, we operate three major processing plants strategically located in Zibo, Fushun, and Nanjing. Our facility lines enjoy structural access to continuous, high-purity C5 and C9 raw chemical feedstocks supplied directly by national energy giants SINOPEC and PetroChina.
This secure feed integration ensures our production runs of C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 resins, dicyclopentadiene (DCPD) resins, and methyl cyclopentadiene dimer maintain exceptional consistency. These materials serve as critical components in industrial hot-melt adhesives, road marking paints, printing inks, and synthetic rubber compounds.
In addition to our core silicone and resin businesses, Boctok plays a key role in the agrochemical synthesis industry. We develop, manufacture, and distribute critical intermediates used in the formulation of fungicides, herbicides, insecticides, and specialized seed treatments. By focusing on eco-friendly synthesis methodologies, we produce stable organo-intermediates that enhance active ingredient delivery and shelf-life, ensuring robust plant crop yields worldwide.
To meet the rising global demand for advanced silane coupling solutions, Boctok recently completed a major US$65 million investment in Bohai Industrial Park, a provincial-level chemical industry zone in Shouguang City, Shandong Province. This state-of-the-art facility significantly strengthens our domestic and export logistics while expanding our overall production capabilities.
Procuring chemical raw materials on a global scale requires strict adherence to international safety standards, technical specifications, and logistical timelines. Large-scale plastic compounding enterprises, automotive tier-one suppliers, and paint manufacturers demand more than just competitive pricing; they require a secure, long-term supply partner.
Global buyers require comprehensive technical documentation, including verified Gas Chromatography (GC) purity charts, refractive index values, viscosity reports, and heavy-metal analysis certifications.
Automated injection molding and continuous extrusion processes require minimal formulation variation. Our advanced synthesis control systems ensure tight batch-to-batch consistency.
With dedicated logistics hubs located near Qingdao port and key railway networks, Boctok provides optimized door-to-port and door-to-door chemical shipping services globally.
Organosilicones and petroleum resins are core components across many industrial applications. By tailoring our formulations, we address specific performance requirements in diverse regional markets:
Boctok's organosilicone products and hydrocarbon resins are key components across many essential manufacturing sectors:

High-performance silicone emulsion defoamers designed for textile processing, water treatment, and pulp milling.
Silane and silicone water repellents designed for gypsum boards, dry-mix mortars, and exterior insulation systems.
Navigating cross-border trade in the global chemical sector requires strict compliance with international regulations. Shandong Boctok Chemical Co. maintains high compliance standards, ensuring all products shipped internationally meet the necessary regulatory requirements:
Our core silane coupling monomers and resins are registered and compliant with European REACH and US TSCA regulations. This guarantees smooth customs clearance and regulatory compliance for our international buyers.
We supply multi-language Safety Data Sheets (SDS) and product labels formatted according to local GHS standards, facilitating safe transport, warehousing, and handling in every destination country.
Under the BOCTOK™ brand, our products undergo EAC certification, simplifying import procedures and distribution within the Russian Federation and Eurasian Customs Union markets.
The versatility of our organosilicone chemistry supports high-value technical industries. In wind energy applications, our silane coupling agents are used to treat structural glass fibers in epoxy-composite blades, enhancing interlaminar shear strength and fatigue resistance in demanding marine environments.
Functional crosslinkers and modifiers that optimize curing density and improve chemical resistance in casting resins.
Water-repellent silane coatings designed for concrete infrastructure, bridges, and building envelopes.
Glass fiber sizing agents that improve interfacial adhesion and moisture resistance in composite wind blades.
High-purity medical-grade liquid silicones and coupling agents used in healthcare devices and diagnostic equipment.

The global coupling agent and hydrocarbon resin sectors are transitioning toward sustainable chemistry, safer worker environments, and enhanced performance capabilities. At Boctok, our R&D roadmap focuses on three major industry shifts:
Traditional coupling agents release methanol or ethanol during hydrolysis. Next-generation oligomeric silanes minimize VOC release during compounding, helping processors meet environmental regulations.
To reduce reliance on fossil resources, we are researching the modification of C5/C9 petroleum cuts with bio-terpenes, creating eco-friendly tackifier resins for adhesive applications.
Combining the elasticity of silicones with the mechanical strength of acrylics or polyurethanes, hybrid silane-terminated polymers (STP) are gaining traction in sealant markets.
