Direct from our manufacturing hubs: certified high-purity solvents & specialized fine intermediates
Founded in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an authoritative leader in high-performance aromatic solvents, specialized heat transfer oils, and structural intermediate chemicals. Located at No.207, WeiLiu Road inside the prestigious Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, we leverage localized industrial cluster advantages and key relationships with domestic refining behemoths—such as Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical—to feed our expansive production pipeline.
From initial configurations addressing domestic basic solvent需求 (serving core economic zones including Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan), Saier Chemical has successfully scaled its systems to reach global compliance metrics. Today, our highly optimized logistics and compliance infrastructure support critical downstream industries across Asia, Europe, the Americas, and Southeast Asia, offering robust alternatives to generic solvent formulations.
Through strategic engineering audits and investment in advanced column fractionation setups, Saier Chemical has consolidated a massive annual capacity. Our specialized product ranges balance ecological standards and processing efficiency:
An in-depth look at solvent synthesis, technical roadmaps, and global industrial integration.
Modern chemical processing demands more than simple solvency properties. Today's global procurement framework relies heavily on stringent quality control, environmental regulatory alignment, and long-term cost efficiencies. Across major industrial sectors—ranging from advanced automotive coatings to specialized agrochemical carriers—procurement directors look for partners capable of delivering specialized boiling point profiles, high flash points, and minimal volatile organic emissions.
A critical shift is underway from basic commodity solvents towards high-boiling aromatic hydrocarbons, commercially known under categories such as S-100, S-150, S-150ND, and S-200. These solvents consist of complex C9 to C12 alkylbenzenes, naphthenes, and heavy aromatic fractions. The demand is further divided by regional regulatory protocols such as Europe's REACH regulations, US EPA guidelines, and China's environmental action plans. Consequently, obtaining solvents with highly managed toxicological parameters—such as low-naphthalene grades (Naphthalene content <1% or even <0.1% in S-150ND)—is crucial for manufacturing organizations operating within strict chemical compliance regimes.
As applications become more specialized, standard formulations no longer suffice. Shandong Saier Chemical provides tailored macroscopic solutions to address distinct industrial engineering pain points:
| Solvent Grade | Compositional Focus | Boiling Range (°C) | Flash Point (°C) | Key Applications |
|---|---|---|---|---|
| Aromatic Solvent S100 | C9 Alkylbenzenes | 160 - 180 | > 42 | Paints, Agrochemical EC, Printing Inks |
| Aromatic Solvent S150 | C10 Alkylbenzenes & Naphthalene | 180 - 210 | > 62 | Coatings, Industrial Cleaning, Oilfield Chemicals |
| Aromatic Solvent S150ND | C10 Naphthalene Depleted (< 0.9%) | 182 - 208 | > 63 | Eco-friendly Agrochemicals, Coil Coatings |
| Aromatic Solvent S200 | C11 - C12 Hydrocarbons | 230 - 290 | > 100 | High-bake Coatings, Liquid Pesticides, Foundry Resins |
| Heat Transfer Oil L-QC320 | Refined Hydrogenated Hydrocarbons | > 320 (Decomp) | > 180 | Thermal Fluid Exchanges, Heat Circulation Systems |
Shandong Saier Chemical’s technical roadmap prioritizes high-performance formulations combined with sustainable manufacturing practices. Operating within the Qilu Chemical Industrial Park, our production facilities utilize continuous fractionation columns, advanced distillation technologies, and hydro-desulfurization loops to minimize aromatic impurities and volatile organic compounds (VOCs).
To support global carbon reduction goals, we have implemented energy optimization protocols throughout our Zibo facilities. This includes integrating heat exchangers on distillation towers and installing Zeolite Rotors for high-efficiency VOC capture and destruction. Looking ahead, our R&D is focused on bio-based solvent integration, advanced naphthalene depletion methods, and expanding our synthetic monomers catalog to serve the growing polyimide and high-temperature polymer markets.
Chemical supply chain reliability is a primary concern for procurement teams. The chemical industry often faces disruptions due to raw material shortages and volatile logistics. Saier Chemical addresses these concerns through long-term raw material agreements with key national and global oil companies, including Sinopec and Hengli Petrochemical.
This vertical integration ensures consistent feedstock supply even during market fluctuations. Our proximity to Zibo's transport network and major Chinese export ports allows for flexible shipping options, including ISO tanks, flexibags, and standard steel drums, ensuring timely delivery to international destinations.

A technical understanding of chemical properties is essential for correct product selection. Each of our chemical products is manufactured under strict quality control to meet industry standards:
Aromatic Solvent S100 (CAS No.: 64742-95-6): Composed mainly of C9 hydrocarbons, S100 offers a balanced evaporation rate and high solvency, making it a standard choice for paint, coating, and agricultural pesticide formulations.
Pyromellitic Dianhydride (PMAD) (CAS No.: 89-32-7): This high-purity crystalline white powder is an important curing agent for epoxy resins and a key monomer for synthesizing polyimide films used in high-temperature electrical insulation.
Dimethyl Disulfide (DMDS) (CAS No.: 624-92-0): An organic sulfur compound widely used as a sulfiding agent in petroleum refining catalysts, and as an intermediate in pesticide production and fine chemical synthesis.
Aromatic Solvent S200 (CAS No.: 64742-94-5): Formulated with C11-C12 hydrocarbons, S200 provides a high flash point (>100°C) and low volatility, suitable for high-bake industrial coatings, oilfield chemicals, and mining extraction processes.

Expert answers to common chemical procurement, application, and compliance questions
The main difference lies in the naphthalene content. Standard S150 contains up to 8-10% naphthalene, whereas S150ND (Naphthalene Depleted) is processed to reduce naphthalene levels to below 1.0% (and often below 0.1%). This meets strict environmental and safety regulations for agricultural and coating applications without compromising solvent performance.
L-QC320 heat transfer oil is formulated from highly refined, hydrogenated base oils with thermal stability additives. It resists thermal cracking and oxidation at operating temperatures up to 320°C, reducing sludge formation and keeping heat exchange surfaces clean for consistent thermal efficiency.
C9 and C10 aromatic solvents (S100, S150) offer higher solvency for organic resins, active agrochemical ingredients, and elastomeric polymers. Their controlled evaporation rates, high flash points, and low surface tension provide better leveling and film formation in coatings compared to aliphatic solvents.
Our manufacturing processes are certified to ISO 9001, ISO 14001, and ISO 45001 standards. Each batch of solvents and fine chemical intermediates undergoes rigorous GC and HPLC testing to verify purity, distillation range, and compliance with target specifications.
We maintain long-term supply agreements and direct pipeline connections with major refiners like Sinopec and PetroChina. This reliable source of petrochemical feedstocks ensures stable production and consistent product quality for our global customers.
