Founded in December 2004 and anchored inside the strategically vital Qilu Chemical Industrial Park (Linzi, Zibo City, Shandong Province), Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an authoritative voice in high-boiling hydrocarbon separation, fine organic synthesis, and process heat management.
Backed by a solid registered capital of 60 million yuan and operating an advanced refining base with a total annual processing capacity of 720,000 metric tons, Saier Chemical specializes in the development, fractionation, and distribution of high-purity aromatic solvents. Our flagship product lines—including S100, S150, S150ND, S180, and S200—function as crucial performance components across global agrochemical formulations, advanced industrial coatings, oilfield process chemistry, and heavy resin processing systems.
By cultivating direct upstream channels with petrochemical giants like Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, we guarantee feedstock purity, stable carbon-cut profiles, and uninterrupted year-round supply chains. Our operational structure bridges the gap between raw refinery outputs and the stringent requirements of international chemical standards.
For B2B procurement managers and chemical formulation engineers, matching precise performance metrics is critical. Aromatic solvents (often designated under commercial names like Solvent Naphtha, TOPSOL, KOCOSOL, or Solvesso equivalents) are classified by their boiling points, flash points, and aromatic hydrocarbon concentrations. Below is our standard engineering matrix detailing the distillation cuts and physical properties of our key aromatic streams:
| Aromatic Grade | CAS Number | Boiling Range (°C) | Flash Point (°C) | Kauri-Butanol (KB) | Principal Hydrocarbon Type | Primary Industrial Use |
|---|---|---|---|---|---|---|
| Aromatic S100 | 64742-95-6 | 160 – 180 | ≥ 40 | 90 – 95 | C9 Alkylbenzenes | High-gloss coatings, printing inks, concrete sealers |
| Aromatic S150 | 64742-94-5 | 180 – 210 | ≥ 62 | 92 – 98 | C10 Alkylbenzenes & Naphthalenes | Agrochemical EC formulations, industrial resins |
| Aromatic S150ND | 64742-94-5 | 184 – 208 | ≥ 63 | 92 – 97 | C10 (Naphthalene Depleted < 0.1%) | Eco-compliant crop protection, automotive coatings |
| Aromatic S180 | 64742-94-5 | 200 – 250 | ≥ 80 | 88 – 94 | C10 – C12 Heavy Aromatics | Baking enamels, slow-drying industrial coatings |
| Aromatic S200 | 64742-94-5 | 230 – 290 | ≥ 100 | 85 – 92 | C11 – C14 Di/Tri-cyclic Aromatics | Oilfield chemicals, high-temperature reaction media |
Our aromatic chemistry solutions are systematically formulated to meet the high-intensity performance demands of global manufacturing, chemical processing, and agricultural protection.
Serving as highly efficient, low-phytotoxicity carrier solvents for Emulsifiable Concentrates (EC), Suspension Concentrates (SC), and micro-emulsions. Our S150ND (Naphthalene Depleted) solvent prevents crystallization at low storage temperatures, maintaining active ingredient efficacy without environmental toxicity penalties.
Used as key diluents and flow control agents in automotive finishes, coil coatings, container paints, and baking enamels. High solvating power enables low-viscosity resin systems, providing superior leveling, gloss retention, and uniform curing profiles in automated coating lines.
Heavy aromatic fractions (specifically our S200 cuts) demonstrate excellent solvency for heavy organics. They are widely applied as asphalt dispersants, corrosion inhibitors, paraffin removers, and drilling fluid formulations designed for high-temperature and high-pressure downhole environments.
As the international regulatory environment shifts toward lower Volatile Organic Compound (VOC) profiles and stricter hazard classifications, the design of industrial solvents must evolve. Shandong Saier Chemical has established a clear technical roadmap that prioritizes green chemistry and process efficiency:
By upgrading to multi-stage, high-vacuum column setups, we achieve narrow boiling-range windows (within 5°C to 8°C variance). This precise control minimizes volatile lighter fractions and reduces heavy residuals, ensuring consistent evaporation behavior and stable flash points across batches.
To assist formulation partners in meeting global eco-label requirements (such as Blue Angel, EU Ecolabel, and EPA regulations), our production line incorporates catalytic hydrogenation and selective absorption systems. These processes reduce naphthalene impurities in our S150ND and S200ND lines to below 0.1% or 1000 ppm, removing hazard warning requirements on finished products.
Additionally, we have optimized our plant utility systems by integrating energy recovery setups, high-performance Zeolite Rotors for VOC capture, and localized heat recycling. These technologies reduce our carbon footprint per metric ton of solvent, supporting the environmental goals of our global distribution partners.
With two decades of specialized operational experience, we provide consistent quality, technical reliability, and efficient logistics for chemical distribution networks.
Direct pipeline and rail links to major refiners ensure feedstock stability, protecting our customers from raw material shortages.
Located in Shandong's chemical hub, we access deep-water ports (Qingdao) and regional rail networks to ensure reliable bulk liquid exports.
We support international compliance protocols, including EU-REACH registration assistance, GHS safety data sheets, and custom chemical documentation.
Review answers to common technical, logistical, and safety questions regarding our aromatic solvents and fine chemicals.
A: Standard Aromatic S150 contains 8% to 15% naphthalene by weight, which can crystallize at temperatures below 0°C and is subject to specific hazard labeling. S150ND (Naphthalene Depleted) undergoes additional separation to reduce naphthalene content to below 1.0% (often < 0.1%), improving low-temperature stability and reducing hazard classification requirements.
A: Our feedstock is sourced directly from major refiners like Sinopec and PetroChina. Combined with our automated Honeywell DCS control systems, we maintain consistent distillation parameters, Kauri-Butanol values, and density profiles across batches.
A: We support bulk logistics configurations, including ISO tanks (20-24 tons), flexitanks for dry containers, standard 200L steel drums (180kg net), and IBC totes. All options are packaged with proper labeling and certificates for international transit.
A: Yes, we provide full GHS Safety Data Sheets (SDS) in multiple languages. We assist our clients with REACH registrations in the EU and equivalent frameworks in other export regions, ensuring full regulatory compliance.
A: Yes, our research division can customize boiling curves, solvency parameters, or flash points for large contracts by adjusting the fractional distillation cuts.
A: Standard lead times from our Zibo facility to loading ports (such as Qingdao) are 7 to 10 days. Marine transit times vary depending on the destination, and we provide transparent tracking throughout the shipping process.
