A deep dive into the chemical profile, purity standards, and performance properties of S-150 (Solvent Naphtha C10 Fraction).
Aromatic Solvent S-150 (also widely designated as heavy aromatic naphtha or solvent naphtha 150) is a complex mixture of C10-C12 aromatic hydrocarbons. Main constituents include alkylbenzenes (such as trimethylbenzenes and tetramethylbenzenes), indene, naphthalene, and alkylnaphthalenes.
Characterized by a boiling range of 179°C to 214°C and a high flash point (typically exceeding 62°C), S-150 offers superior safety profiles for high-temperature applications compared to lower-boiling point aliphatic or aromatic alternatives. Its high solvency power (Kauri-Butanol value typically >90) makes it the solvent of choice for resin dissolution and complex agrochemical emulsifiable concentrates (EC).
At Shandong Saier Chemical, we process raw C10 feedstocks via multi-stage fractionated distillation to isolate premium grades. For markets with strict toxicity guidelines, we supply S-150ND (Naphthalene Depleted), reducing naphthalene content below 1.0% (and down to 0.1% on demand) to comply with stringent occupational health regulations.

| Density @ 15°C (g/cm³) | 0.890 - 0.910 | ASTM D4052 |
| Initial Boiling Point (°C) | Min. 179 | ASTM D86 |
| Dry Point (°C) | Max. 214 | ASTM D86 |
| Flash Point (Closed Cup, °C) | Min. 62 | ASTM D93 |
| Aromatic Content (vol%) | Min. 99.0 | ASTM D1319 |
| Naphthalene Content (%) | < 1.0 (ND Grade available) | GC Analysis |
As global regulations tighten on volatile organic compounds (VOCs) and hazardous air pollutants (HAPs), the technological pathway for S-150 is undergoing significant innovation.
Advanced deep hydrodesulfurization (HDS) and extractive distillation processes allow us to target naphthalene reduction. Our process maintains high aromaticity (>99%) while decreasing the naphthalene marker to non-detectable levels, ensuring full compliance with REACH and OSHA exposure limits.
Researching hybrid mixtures combining high-boiling aromatics with bio-based esters (e.g., alkyl lactates or fatty acid methyl esters). This technological route lowers net carbon intensity and improves biodegradability parameters without compromising the high-solvency characteristics required for heavy resins.
Leveraging digital DCS systems and real-time gas chromatography loops, we tailor S-150 boiling point profiles to reduce lower-boiling fractions (VOC optimization) or high-boiling fractions (drying time control), matching specific curing speeds of performance coatings.
Our Aromatic Solvent S-150 acts as a core formulation foundation across essential global industrial sectors.
Essential carrier for Emulsifiable Concentrates (EC), Suspo-emulsions (SE), and Micro-emulsions (ME). The extreme solubility parameters of S-150 ensure that active ingredients (pesticides, herbicides, and fungicides) remain stable without crystallization under diverse storage temperatures.
Used extensively in automotive OEM coatings, coil coatings, industrial baking enamels, and marine protective coatings. Its uniform evaporation rate allows paint films to level perfectly, preventing defects such as pinholes, orange peel, and blistering.
Serves as a high-performance dissolver for paraffin wax, asphaltenes, and heavy oil residues in wellbore treatments. It also acts as a carrier fluid for refinery process chemicals, corrosion inhibitors, and drag-reducing agents.
How Shandong Saier Chemical combines automation, scale, and geographic advantages to guarantee uninterrupted global supply.
Our facility at the Qilu Chemical Industrial Park is directly connected to regional refining hubs via pipelines. This structural advantage reduces overland transportation risks and ensures a constant stream of high-purity C10 raw materials from Sinopec and PetroChina.
With an annual capacity of 720,000 tons, our facility is equipped with automated fractional distillation columns utilizing advanced packing materials. This setup guarantees extremely tight control over molecular cuts and boiling ranges.
Our storage capabilities include dedicated tank farms with over 50,000 cubic meters of capacity, facilitating rapid loading of bulk vessels, ISO tanks, and flexitanks. This infrastructure mitigates geopolitical and seasonal logistical disruptions, keeping supply lines stable year-round.
Exporting industrial solvents requires adhering to international regulatory frameworks. We guarantee full compliance and provide localization support.
Shandong Saier Chemical provides full EU REACH registration support for importers. All shipments are accompanied by GHS-compliant Safety Data Sheets (SDS) and labeling in local languages, detailing precise toxicological, ecological, and handling profiles.
Our facility runs under certified management systems, including ISO 9001:2015 for quality management, ISO 14001:2015 for environmental compliance, and ISO 45001:2018 for occupational health and safety standards.
Through partnerships with chemical distributors, we support localized inventory management solutions, including vendor-managed inventory (VMI) and safety stock buffers at primary international ports of entry.
Key considerations for procurement managers when selecting a long-term manufacturer of high-boiling aromatic solvents.
Aromatic Solvent S-150 performance depends directly on the purity of the raw C10 stream. Variations in paraffinic or olefinic fractions alter solubility parameters and cause color degradation. Saier Chemical’s direct supply lines with Sinopec eliminate these variances.
We accommodate varied logistics profiles by offering:
Strict controls over sulfur and chlorine parameters are critical to protect downstream catalysts. Our S-150 maintains sulfur contents far below typical industrial specifications (typically < 5 ppm), protecting sensitive equipment and processes.
Addressing technical queries and compliance issues related to Aromatic Solvent S-150 procurement and applications.
Providing reliable chemical intermediate solutions for global distributors and industrial manufacturers.
