Explore our primary array of high-purity silane coupling agents, specialized organosilicon intermediates, and industrial additives tailored for global distribution.
The international silicone industry has entered an era of refined high-performance manufacturing, primarily dominated by advanced production hubs in China. Standard poly-dimethylsiloxane (PDMS) and its multi-functional derivatives—such as silanol polymers, vinyl silicone oil, and phenyl silicone oil—serve as the foundation for modern electronics, structural infrastructure, aerospace engineering, and cosmetics formulation.
As industrial requirements pivot toward stricter regulatory standards (such as EU REACH, RoHS compliance, and micro-contaminant minimization), manufacturers are leveraging automation and catalytic efficiency. This shift ensures the structural integrity of polymeric bonds, offering extreme high-and-low temperature stability, dielectric reliability, and excellent hydrophobic capabilities.
Leading chemical synthesis and distribution infrastructure serving specialized global markets.
Founded in 2012 as a global marketing and sales center, Shandong Boctok Chemical Co. has established itself as an industry leader, achieving sales of US$280 million in 2023. Operating under the BOCTOK™ brand, we have built a powerful supply reputation, specializing extensively in the Russian and Eurasian markets.
Our core organosilicone business spans twelve specialized 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.
Furthermore, Boctok's chemical line produces highly specialized silicone fluids and resins, 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, RTV methyl silicone rubber, 110 methyl vinyl silicone rubber, and 120 methyl phenyl rubber.
Boctok's Tier II core business centers around advanced petroleum resins. Backed by strategic investments in key hydrocarbon resin manufacturing facilities located in Zibo, Fushun, and Nanjing, we access high-grade raw materials directly from SINOPEC and PetroChina.
Our production portfolio includes C9 hydrogenated resins, C5 hydrocarbon resins, C5 modified C9 resins, dicyclopentadiene (DCPD), and methyl cyclopentadiene dimer. Additionally, we provide intermediates and raw materials for the synthesis of crop protectors, insecticides, fungicides, and seed treatments.
To meet surging international demand, Boctok recently invested US$65 million to construct a brand-new facility in Bohai Industrial Park, Shouguang City, Shandong Province.
Mapping out the trajectory of the silicone and organosilicon markets over the next decade.
Industrial demand is rapidly transitioning to low-VOC, carbon-neutral manufacturing. Our new facility structures production around eco-friendly waste recycling networks. By reducing cyclic siloxanes (D4, D5, D6), we ensure regulatory compliance with strict global environmental agencies.
The rise of high-speed computing and electric vehicles requires high-purity, low-outgassing phenyl silicone oils. These serve as thermal interface materials (TIMs) and heat-dissipating fluids, shielding delicate electronics from extreme thermal stress.
Standard commodity silicones are giving way to custom-engineered block copolymers. By tuning the ratio of methyl, vinyl, and phenyl groups, we customize viscosity, refractive indices, and cross-linking kinetics for specialized applications.
Bridging the gap between raw organosilicon synthesis and real-world industrial integration.
Specialized silicone surfactants and adjuvants dramatically lower the surface tension of water, allowing agricultural formulations to spread uniformly across crops.

A deep technical examination of structural kinetics, linkage chemistry, and polymer formulation.
Silane coupling agents act as essential bridges between inorganic substrates (such as glass fibers, silica, and minerals) and organic polymer matrices. The general chemical formula of a silane coupling agent is Y-R-Si-X₃. Here, X represents hydrolyzable groups (typically methoxy or ethoxy) that react with inorganic hydroxyl groups to form stable siloxane bonds (Si-O-Si). The group Y is an organofunctional group (such as amino, epoxy, vinyl, or methacrylate) designed to react with the polymer resin during curing. This chemical configuration prevents structural delamination under extreme mechanical and environmental stress.
Choosing the right silicone fluid depends on your application's thermal and chemical requirements:
| Silicone Oil Type | Key Chemical Properties | Primary Applications |
|---|---|---|
| Vinyl Silicone Oil (CAS 26710-23-6) | Functional vinyl group terminations; high reactivity with hydride crosslinkers via hydrosilylation. | Liquid Silicone Rubber (LSR) bases, potting compounds, structural modifiers. |
| Phenyl Silicone Oil | High phenyl ring content; exceptional thermal limits (-50°C to 250°C), radiation resistance, and high refractive index. | High-temperature lubricants, heat transfer systems, optical packaging. |
Organosilicone fluids modified with polyether chains exhibit superspreading properties. Known as trisiloxane surfactants, these adjuvants lower the aqueous surface tension of agricultural spray solutions to below 21 mN/m. This ensures the chemical spreads evenly over hydrophobic leaf cuticles, improving agricultural chemical absorption and reducing run-off, which helps prevent soil contamination.
