Explore our high-purity chemicals, intermediates, and industrial aromatic compounds sourced for global distribution.
The global chemical manufacturing sector is witnessing a paradigm shift. Industrial formulations increasingly demand higher solvency parameters combined with safer, high-flashpoint profiles to align with tightening environmental and occupational health safety (OHS) regulations. This regulatory pressure has driven the industrial adaptation of high-temperature aromatic hydrocarbon fluids, predominantly categorized as C9, C10, and C11-C12 fractions, commercially known under the Topsol A100, Topsol A150, and Topsol A200 series.
Historically, solvent naphtha has served as the backbone of industrial coatings, agricultural emulsifiable concentrates (EC), and printing inks. However, contemporary requirements demand low-naphthalene configurations (such as S150 ND / S150 LN) and high-boiling process oils that maintain thermal stability under extreme mechanical loads. Shandong Saier Chemical Technology Development Co., Ltd. addresses this evolution by offering high-purity C9-C12 aromatic fractions that satisfy rigorous international distillation standards.
Understanding the key thermodynamic and chemical differences between Topsol A100, A150, and A200 to optimize your formulation parameters.
| Product Grade | Composition Classification | CAS Registry Number | Boiling Range (°C) | Flash Point (PMCC, °C) | Primary Industrial Applications |
|---|---|---|---|---|---|
| Topsol A100 (S-100) | C9 Aromatic Hydrocarbon Fraction | 64742-95-6 | 160 – 180 | > 42 | High-bake coatings, agrochemical EC formulations, industrial resins. |
| Topsol A150 (S-150 / S-150 ND) | C10 Aromatic Hydrocarbon Fraction | 64742-94-5 | 180 – 210 | > 62 | Pesticides, low-naphthalene coatings, screen printing inks, oilfield recovery. |
| Topsol A200 (S-200) | C11 - C12 Heavy Aromatic Fraction | 64742-94-5 | 230 – 290 | > 100 | Heat transfer fluids, foundry resins, high-temperature coatings, lubricant blending. |
Utilizing high concentration of C9 aromatic isomers, Topsol A100 provides superior resin compatibility, helping paint manufacturers achieve low viscosity with excellent flow properties.
Designed with safety in mind, our C10 fractions offer flashpoints above 60°C, reducing warehouse hazards while meeting international green emission directives.
Operating efficiently up to 290°C boiling point, A200 serves as a resilient medium for high-temperature chemical reactions and heavy-duty industrial degreasing agents.
Navigating the complex sourcing challenges of downstream buyers in America, Europe, Asia, and the Middle East.
For mid-to-large-scale buyers, supply continuity is a critical operational KPI. In today's volatile energy market, interruptions in aromatic solvent feedstock supply can disrupt global paint and pesticide manufacturing schedules. Shandong Saier Chemical Technology Development Co., Ltd. addresses this challenge through strategic integrations with major state-run refining networks, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical.
Our facility, situated within the **Qilu Chemical Industrial Park** (Linzi, Zibo City, Shandong Province), leverages this geographic proximity to major refineries. It ensures a stable feedstock intake, supporting our **720,000 tons per year** production capacity. This reliable supply chain allows us to maintain stable production of high-boiling aromatic solvents (S-100, S-150, S-150ND, S-180, and S-200), durene, PVC plasticizers, and other critical fine chemicals.
How Topsol A100, A150, and A200 drive efficiency across global industrial applications.
In the crop protection industry, Topsol solvents act as carrier media for active ingredients in Emulsifiable Concentrates (EC) and Micro-emulsions (ME). Topsol A150 (particularly Low-Naphthalene grades) prevents phytotoxicity while ensuring high solubility for active molecules like pyrethroids and triazoles.
Industrial baking finishes demand solvents with precise evaporation profiles. Topsol A100 provides controlled release times, preventing surface defects like blistering, pinholes, and orange peel in automotive, coil, and appliance coatings.
For high-temperature heat transfer systems, Topsol A200 serves as a reliable heat transfer oil component (comparable to L-QC320 standards). Its high thermal degradation threshold ensures longer service life and reduced oil-cracking in closed-loop systems.
Navigating global regulatory landscapes requires chemical suppliers to provide comprehensive, transparent support. As an ISO-certified chemical exporter, Shandong Saier Chemical provides full compliance documentation, including:
Shaping the future of industrial chemistry through green processing and innovative refining techniques.
We are optimizing our continuous rectification technology to narrow boiling cuts further. This reduces volatile organic compound (VOC) emissions during application, helping clients meet national carbon neutral targets.
Our engineering team is testing industrial solvent recovery integrations. This allows downstream paint and paint-strip manufacturing plants to re-refine spent solvents, reducing raw material footprint.
By upgrading our thermal distillation systems with high-efficiency heat exchangers and automated control loops, we have reduced carbon intensity per ton of Topsol output by 12% since 2021.
