Founded in December 2004 with a solid registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as a premier destination for industrial-grade organic solvents and intermediates. Located strategically at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, we thrive within one of China's most advanced chemical clusters.
Initially focusing on the domestic processing of baseline petrochemical fractions, the company has integrated structural downstream supply pipelines with industry leaders including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. This guarantees a continuous, ultra-pure feedstock configuration, ensuring our raw material chemistry meets stringent international specifications from the very source.
Today, boasting a robust production capacity of 720,000 tons per year, Saier Chemical serves both domestic hubs (Beijing, Shanghai, Tianjin, He河北, Shandong, Henan) and expanding international channels across Asia, Europe, the Americas, and Southeast Asia. We represent reliability in high-performance aromatic hydrocarbon chemistry.
720,000-Ton Infrastructure: Multi-column continuous rectification systems designed to deliver tight-cut boiling ranges and custom solvent profiles.
Strategic Feedstock Integration: Deep commercial integration with domestic mega-refiners keeps our supply resilient against macro-market shocks.
Eco-Innovation: Active investment in low-naphthalene derivatives (ND series) matching global environmental guidelines (VOC mitigation and REACH compliance).
Worldwide environmental policies (such as the EU's Decopaint Directive and EPA Clean Air Act mandates) are forcing formulators to transition away from highly volatile aromatic hydrocarbons. There is a surging demand for heavy, high-boiling point aromatic solvents (distillates boiling in the 160°C to 220°C+ range, such as S-150 and S-200) that offer low evaporative loss profiles, lowering overall volatile organic compounds (VOC) emissions while maintaining high solvating capabilities.
Naphthalene is increasingly classified as a hazard by global chemical agencies. Industries like agrochemical formulation (EC/OD pesticides) are rapidly phasing out standard solvents containing 5–10% naphthalene. This has elevated naphthalene-depleted (ND) aromatic solvents, such as Aromatic Solvent S150ND (CAS 64742-94-5), which limit naphthalene content to under 1% or even under 0.1% to guarantee user safety and minimize ecological impact.
Modern paint, varnish, and polyurethane systems require tailored evaporation curves. High-boiling solvents (S100, S150, S200) are utilized alongside acrylic and alkyd resin bases to optimize leveling, prevent pinholes, and improve gloss. OEM manufacturers are focusing on custom-fractionated cuts that allow chemical engineers to adjust solvent release kinetics inside automated drying booths.
Corporate procurement of commodity and specialty aromatics requires strict adherence to supply security, quality uniformity, and logistical flexibility. Saier Chemical works directly with chemical buyers to address three key operational requirements:
Global enterprises cannot afford variations in solvent purity. For instance, in the formulations of pesticides, emulsifiable concentrates (EC) require highly consistent solubility performance. A variation of even 1% in aromatic purity can cause active ingredients to crystallize out of solution during cold transport.
By enforcing an ISO-certified supply flow from refining to distillation, Shandong Saier Chemical provides consistent, high-purity aromatics. Standardizing solvent chemistry reduces unexpected batch failures for downstream pesticide, adhesive, and coating producers.
We leverage advanced high-vacuum rectification columns to separate close-boiling hydrocarbon fractions. This allows us to separate components with minor boiling point variances, ensuring our S-100 and S-150 products feature low residue limits and consistent chemical compositions.
Meeting the low-naphthalene target without reducing aromaticity is a key chemical challenge. Our R&D team uses advanced catalytic processes that selectively hydrogenate or extract naphthalene compounds. This maintains the high solvency power of the C10-C12 aromatic core while ensuring regulatory safety compliance.
We have integrated VOC-absorption Zeolite Rotor units alongside modern thermal destruction setups. These technologies capture fugitive hydrocarbon emissions during loading and processing, helping our factory meet international low-carbon chemical production standards.
The main difference lies in their boiling ranges, flash points, and chemical compositions. Aromatic Solvent S100 (CAS 64742-95-6) is primarily composed of C9 aromatics with a distillation range of 160°C to 180°C and a flash point of ~43°C. Aromatic Solvent S150 (CAS 64742-94-5) consists of C10 aromatics with a higher boiling range of 180°C to 210°C and a flash point of ~62°C, making S150 suitable for processes requiring higher thermal stability and lower evaporation rates.
Our S150ND undergoes a specialized post-rectification process. Through controlled fractionation and targeted adsorption, we reduce the naphthalene content from the typical 5–10% down to below 1.0% (often <0.1%). This ensures compliance with EU and US EPA environmental regulations without degrading the solvent's ability to dissolve active chemical agents.
Every batch of our aromatic solvents undergoes rigorous analysis in our quality control laboratory. We use ASTM methods to test key properties, including distillation range (ASTM D86), flash point (ASTM D93), color index (ASTM D1209), and detailed aromatic content via Gas Chromatography (GC-MS). Quality certificates (COAs) are issued for every shipment.
Yes. With our multi-tower distillation systems and custom blending tanks, we can tailor distillation cuts, boiling points, and solubility parameters (such as KB value and aniline point) to match our clients' unique technical requirements.
Navigating global chemical regulations requires extensive regulatory expertise. Shandong Saier Chemical provides comprehensive compliance support, including GHS-compliant Safety Data Sheets (SDS) in multiple languages, REACH registrations for European markets, and custom packaging configurations that meet IMDG regulations for marine shipping.
Whether shipping in bulk vessel compartments, ISO tanks, or standard 200L steel drums, our cargo logistics team coordinates with port officials and ocean carriers to ensure safe transport. We also offer detailed customs classification support to help streamline import procedures and avoid transit delays.
