Direct sourcing channels for primary chemical agents, derivatives, and industrial raw solvents from Zibo, Shandong Province.
Established in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. is a nationally recognized high-tech enterprise located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province. Over two decades, Saier Chemical has engineered a sophisticated processing infrastructure with an annual production capacity reaching 720,000 tons per year.
Originally focusing on basic chemical outputs, the company specialized in refining premium environmentally friendly high-boiling aromatic solvents. Our product catalog features core compounds including Aromatic Solvents S-100, S-150, S-150ND, S-180, and S-200, heat transfer oils (such as L-QC320), Durene, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG.
To secure uncompromised product quality at the source, we establish direct partnerships with world-class petrochemical refineries including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This guarantees a steady feedstock streamline for global distribution across Beijing, Shanghai, Tianjin, Hebei, Shandong, Henan, and international markets throughout Europe, the Americas, Asia, and Southeast Asia.
How integrated manufacturing hubs enable consistent, high-purity supply for global petrochemical supply chains.
Direct feedstock integration with petrochemical leaders like Sinopec and PetroChina guarantees a continuous supply of crude C9-C10 aromatics. This mitigates raw material pricing fluctuations and enables consistent production runs.
Utilizing advanced multi-stage continuous fractionation columns, we achieve narrow distillation ranges and high purity. This process yields solvents with high solvency power, a high Kauri-Butanol (KB) value, and controlled evaporation rates.
Meeting strict global environmental standards, our purification facilities supply Naphthalene-Depleted (ND) versions of S-100 and S-150. These grades reduce the naphthalene content to less than 1% or 0.1%, satisfying strict eco-toxicity criteria.
Located in Zibo within the Qilu Chemical Industrial Park, our plant features direct access to rail networks, high-capacity pipeline setups, and is situated near Qingdao Port. This location facilitates efficient bulk shipping, ISO tanks, and drum distribution.

*Note: The Aromatic Solvent S100 is produced using crude C9-C10 aromatics via continuous rectification technology. The resulting solvent is a colorless, transparent, and aromatic fluid complying with ASTM D5134, Solvesso 100, and Kocosol 100 specifications.
The global industrial solvent landscape is shifting toward reduced emission profiles and enhanced workplace safety. Key development trends reshaping the Solvent Naphtha market include:
Highly refined aromatic fluids perform key roles across diverse agricultural, coating, and polymer synthesis industries.
S100 serves as a primary carrier solvent for Emulsifiable Concentrates (EC), Emulsions in Water (EW), and Micro-emulsions (ME). It displays excellent solvency for active pesticide ingredients, including pyrethroids and triazoles, maintaining formulation stability across varying temperatures.
In high-temperature baking enamels, coil coatings, and automotive OEM finishes, S100 acts as a diluent that helps regulate viscosity. Its boiling point profile allows for a controlled evaporation rate, preventing surface defects like pinholes, orange peel, and blistering.
The C9 fraction in S100 serves as a feedstock for extracting 1,2,4,5-tetramethylbenzene (Durene). Durene is oxidized to produce Pyromellitic Dianhydride (PMDA), a critical monomer for high-performance polyimide (PI) films used in electronics.
Used in screen-printing formulations, high-build anti-corrosive coatings, marine paints, and specialized resin blending. It offers good compatibility with alkyd, acrylic, epoxy, and polyurethane systems, supporting optimal leveling and adhesion.

Addressing common queries regarding the chemical composition, industrial safety, and procurement processes of C9 aromatic solvents.
Solvent Naphtha 100 (CAS No. 64742-95-6), also known as light aromatic solvent naphtha, consists primarily of C9-C10 aromatic hydrocarbons. The main components are trimethylbenzenes (pseudocumene, mesitylene, and hemimellitene), ethyltoluenes, and propylbenzenes. The aromatic content typically exceeds 99% v/v.
The primary difference is the distillation range and resulting flash point. Solvent Naphtha 100 consists of C9-C10 compounds, boiling between 150°C and 185°C with a flash point of ~42°C. Solvent Naphtha 150 is a heavier fraction (mostly C10-C11 compounds), boiling between 180°C and 210°C with a flash point of ~62°C. Solvent Naphtha 150 is often preferred where higher flash points are required for process safety.
Standard heavy aromatic solvents naturally contain up to 10% naphthalene. Naphthalene-Depleted (ND) grades undergo additional vacuum distillation and separation steps to reduce the naphthalene content to less than 1.0% or 0.1% by weight. This helps meet safety requirements for agricultural and coating applications.
With a high Kauri-Butanol (KB) value of over 90, Solvent Naphtha 100 exhibits strong solvency power. It easily dissolves or swells most elastomers and polymers, including natural rubber, nitrile rubber, and polystyrene. Compatible gasket and seal materials include PTFE (Teflon) and Viton.
Solvent Naphtha 100 is classified as a flammable liquid (Class 3, UN 1268). Storage should be in cool, well-ventilated areas away from heat sources and open flames. Tanks and transfer lines require grounding to prevent static discharge, and vapor recovery systems are recommended to minimize emissions.
We support multiple container configurations: 200L steel drums (180 kg/drum net), 1000L IBC tanks, and bulk ISO tanks (approx. 20-24 tons net). Bulk shipping is also available via chemical tankers from Qingdao Port.
We secure raw C9/C10 aromatic hydrocarbons directly from major domestic refiners like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This feedstock is processed at our Zibo refinery, which has an annual capacity of 720,000 tons.
