Explore our high-purity industrial compounds, fine chemicals, and customized solvent naphtha series manufactured under strict global quality standards.
Aromatic Solvent S150 (scientifically classified under CAS number 64742-94-5, also known as Heavy Aromatic Naphtha) is a highly stable, high-boiling-point organic solvent characterized by its elevated aromatic hydrocarbon content (typically above 99%). It features an evaporation rate optimized for coatings, agrochemicals, and printing inks that demand slow, controlled drying schedules.
From an industrial application perspective, S150 is heavily prioritized for formulating crop-protection products, industrial protective coatings, resins, and automotive chemicals. Its exceptional solubility parameters ensure excellent compatibility with diverse polymers, preventing early evaporation stress and promoting uniform structural curing across target substrates.
Additionally, Saier Chemical's processing techniques yield the specialized S150ND (Naphthalene Depleted) version. This critical variant addresses modern environmental safety frameworks by dropping naphthalene content to below 1.0% (and even down to 0.1% for highly regulated markets), satisfying both OSHA and REACH guidelines for volatile organic compounds (VOCs).
"To succeed in modern industrial sourcing, purchasing directors do not simply look for a chemical seller; they demand high-capacity manufacturing centers that combine technical agility, regulatory backing, and consistent supply security. CAS 64742-94-5 represents the backbone of heavy aromatic formulations globally."
The performance of CAS 64742-94-5 depends heavily on its precise physical-chemical parameters. Saier Chemical guarantees consistency by utilizing top-grade hydrocarbon streams from China’s largest petrochemical plants (including Sinopec, PetroChina, and ChemChina). Below are the typical parameters for Aromatic Solvent S150:
| Parameters | Standard Specification | Saier Guaranteed Limit | Testing Method |
|---|---|---|---|
| Appearance | Clear and Free of Suspended Matter | Conforms | Visual |
| Density @ 15°C (g/cm³) | 0.880 - 0.915 | 0.895 | ASTM D4052 |
| Distillation Range (°C) - IBP | Min 175 | 182 | ASTM D86 |
| Distillation Range (°C) - DP | Max 215 | 207 | ASTM D86 |
| Flash Point (Closed Cup, °C) | Min 62 | 65 | ASTM D93 |
| Aromatic Content (vol %) | Min 99.0 | 99.5 | GC Analysis |
| Naphthalene Content (wt %) | Standard: 8.0 - 10.0 / ND Grade: < 1.0 | ND Option: < 0.9 / Ultra ND: < 0.1 | GC-MS |
| Water Content (ppm) | Max 500 | < 200 | ASTM E1064 |
By tailoring these specifications, we address specific concerns such as high solvency power (Kauri-Butanol value typically around 95), low volatility, high boiling points, and excellent thermal stability. This makes our S150 series a direct alternative to major global equivalents like TOPSOL, KOCOSOL, and SOLVESSO 150.
Operating from Shandong's premier industrial chemical hub, we maximize cost efficiency, logistic agility, and technical compliance.
Located at the Qilu Chemical Industrial Park in Linzi, Zibo City, Shandong, Saier Chemical sits adjacent to China's refining giants. This geographic clustering ensures a constant, uninterrupted pipeline of raw material C10 aromatic streams from companies like Sinopec and PetroChina, shielding our global partners from upstream pricing shocks.
Our annual manufacturing capacity of 720,000 metric tons guarantees that we can fulfill both high-volume spot orders and long-term supply agreements. High-volume continuous rectification towers ensure uniform product quality across batches, minimizing variances that can disrupt downstream automated formulation lines.
As a national recognized high-tech enterprise, we invest heavily in process design. We optimize purification, recycle waste heat, and reduce environmental footprints. Our development of Low-naphthalene (ND) solvents and premium Heat Transfer Oil L-QC320 represents our ongoing commitment to clean production technologies.
Founded in December 2004 with a registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an industry leader. Located in the highly active Qilu Chemical Industrial Park, Zibo City, Shandong Province, we began as a producer of basic organic solvents. Over the past two decades, we have transitioned into a technology-driven fine chemical innovator.
Initially supplying domestic markets in Beijing, Shanghai, Tianjin, Hebei, Henan, and Shandong, our distribution network now serves global markets including Asia, Europe, North America, and South America. Our product line has expanded from standard S-100, S-150, and S-200 aromatic solvents to high-value intermediates, agricultural solvent formulations, PVC plasticizers, and specialty compounds like Durene, 1,3-Cyclohexanedione, MIPK, and more.
Equipped with advanced rectification towers, computerized control rooms, and analytical testing laboratories.
Navigating cross-border chemical shipping requires strict compliance with international regulations. Shandong Saier Chemical provides comprehensive logistics and regulatory support to ensure smooth import operations for global enterprises.
We supply complete documentation packages for customs clearance and regional compliance, including GHS SDS (Safety Data Sheets) in multiple languages, REACH registration certificates for EU buyers, and TCSA compliance declarations for North American markets. We also provide full COA (Certificate of Analysis) validation for every batch before shipment.
Depending on your storage and logistics needs, we offer multiple packaging configurations designed to preserve product purity and ensure safe transport:
Located near Zibo’s shipping hubs, we have direct railway and expressway access to the Port of Qingdao. This strategic proximity simplifies transportation logistics and minimizes port turnaround times, ensuring reliable, on-time delivery to global destinations.
Optimized physical characteristics make S150 a key raw material across high-performance industrial sectors.
Due to its high solvency power for active ingredients, CAS 64742-94-5 serves as a carrier solvent in emulsifiable concentrates (EC), micro-emulsions (ME), and suspension concentrates (SC). It features low phytotoxicity, ensuring it does not damage crops during application.
In industrial stoving enamels, wood coatings, and protective paints, S150 functions as a high-boiling diluent. Its slow evaporation rate enhances levelling and flow properties, preventing surface defects like pinholes, orange peel, and blistering.
With its high flash point (typically >62°C), S150 serves as a safe solvent carrier in degreasing agents, metalworking fluids, and fuel additives. It balances strong solvency with safety, reducing fire hazards in industrial environments.
