Authoritative insights into synthesis technologies, value chains, and microeconomic supply configurations.
Aromatic hydrocarbons form the structural bedrock of the contemporary petrochemical matrix. Essential components like benzene, toluene, xylenes (BTX), and high-boiling aromatic solvents (such as S100, S150, S180, and S200 fractions) act as critical building blocks for advanced polymer materials, pharmaceutical intermediates, pesticide formulations, and specialized coatings.
In the global market, demand is transitioning towards refined fractions with narrow boiling points, minimized environmental footprints, and predictable performance. Sourcing relies heavily on sophisticated refineries and integrated aromatics complexes. The integration of high-performing C9, C10, and heavier aromatic fractions has experienced rapid growth, driven by key end-use sectors including automotive coatings, modern agrochemical delivery systems (like EC and microcapsule suspensions), and synthetic resin matrices.
Major global supply nodes are concentrated near massive refining networks. Industrial parks located in the Asia-Pacific region, especially China's chemical clusters, have consolidated processing structures to offer steady throughput and economies of scale.
Established in December 2004 and located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an innovative, dependable leader in the field of high-boiling aromatic solvents and intermediates.
With an initial registered capital of 60 million yuan, our operational footprint has expanded to achieve an annual production capacity of 720,000 tons. Our primary feedstock is sourced through long-term partnerships with leading domestic refining groups, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This stable supply chain ensures consistent raw material quality and product reliability.
Initially focused on foundational products like S-100, S-150, S-150ND, S-180, and S-200 aromatic solvents, along with heat transfer oils (such as L-QC320) and key intermediates (like durene, PVC plasticizers, thiophene, and 1,3-Cyclohexanedione), we have since transitioned into a national high-tech enterprise. Our target markets span major industrial hubs in China (Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan) as well as global regions including Europe, the Americas, and Southeast Asia.
A structured breakdown of our core chemical outputs, designed for technical validation and procurement comparison.
The product catalog at Shandong Saier Chemical is organized into two primary divisions: Aromatic Solvents (TOPSOL / Naphtha series) and Fine Chemical Materials & Intermediates. Below are the key specifications for our primary aromatic solvents, manufactured via continuous fractionation of reformate and pyrolysis gasoline streams.

Our Aromatic Solvent S100 is produced using crude C10 aromatics for industrial use as raw material and through continuous rectification for separation technology. It is a colorless, transparent, and aromatic organic solvent that complies with international standards for aromatic hydrocarbon solvents.
How our aromatic range is deployed across key industrial verticals globally to optimize solvent strength and stability.
High-boiling aromatic solvents like S150, S150ND, and S200 serve as active ingredient carriers in crop protection formulations (Emulsifiable Concentrates - EC, Oil Dispersions - OD). Their high solubility reduces active ingredient crystallization at low temperatures, ensuring field performance and stable shelf lives.
Our S100 and S150 solvents offer ideal evaporation profiles for industrial baking finishes, coil coatings, and marine anti-corrosive paints. By maintaining wet-film open time, they enable bubble-free levelling and high gloss development in high-temperature cure ovens.
Durene (95-93-2) is oxidized to produce pyromellitic dianhydride (PMDA), a precursor for polyimide films utilized in microelectronics and high-temperature insulation. Other intermediates support pharmaceutical and fine chemical synthesis.
Environmental regulations dictate aromatic solvent profiles globally. In the European Union (REACH directives) and North America (TSCA regulations), there is strong demand for "Naphthalene Depleted" (ND) grades, also classified as "Low Naphthalene" (LN) solvents. These solvents contain less than 1.0 wt% (or even less than 0.1 wt%) naphthalene, minimizing hazardous material classifications. Saier Chemical's S150ND and custom fractionation lines help meet these compliance thresholds, allowing global agrochemical and coating manufacturers to import and distribute products without restrictive labeling requirements.
Pioneering cleaner refining processes, green chemical intermediates, and optimized heat transfer efficiencies.
Shandong Saier Chemical’s technology roadmap focuses on environmental footprint reduction, heat recovery, and high-purity separations. Key initiatives include:
