Direct supply of industry-standard raw materials and specialized fine chemical intermediates.
Founded in December 2004 with a solid registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has established itself as an industry powerhouse. Located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, we leverage Zibo's historical position as one of China's primary chemical manufacturing hubs.
Originally focused on basic petrochemicals, the company developed premium, environmentally friendly high-boiling aromatic solvents (including S-100, S-150, S-150ND, S-180, and S-200), as well as Heat Transfer Oils L-QC320 and core aromatic intermediates. By establishing long-term, direct procurement partnerships with petroleum blockbusters such as Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, we secure uninterrupted access to the highest-grade refinery feedstocks.
Today, boasting an annual production and processing capacity of 720,000 tons, our high-boiling solvents are widely distributed globally across Asia, Europe, the Americas, and Southeast Asia, while maintaining strong partnerships with state energy enterprises like Sinopec and PetroChina.
A deep dive into why "ND" (Naphthalene Depleted) solvents have become the compliance and performance standard for modern industries.
High-boiling aromatic hydrocarbons are excellent solvents due to their superior solvency power (measured by Kauri-Butanol value), uniform evaporation rates, and high flash points. However, traditional standard Aromatic Solvent S-150 contains up to 8% to 10% of naphthalene, a compound classified as a Class 2 carcinogen under GHS (Globally Harmonized System) guidelines and regulated strictly due to its ecotoxicological footprint.
To address these safety concerns, Shandong Saier Chemical introduced the Aromatic Solvent S-150ND (Naphthalene Depleted). Through advanced fractional distillation and selective extraction technologies, we successfully reduce the naphthalene content to less than 1.0% (and optionally below 0.1%), effectively removing the requirement for hazard labels carrying the H351 carcinogenic warning while preserving all key performance advantages of traditional S-150.

|---|---|---|---|
| Naphthalene Content (wt%) | 8.0% - 10.0% | < 0.9% (Low-ND) / < 0.1% (Ultra-ND) | GC-MS Analysis |
| Boiling Range (°C) | 179 - 210 | 181 - 208 | ASTM D86 |
| Flash Point (PMCC, °C) | > 62 | > 63 | ASTM D93 |

Saier Chemical's strategic investment in next-generation green solvents and process intelligence.
By upgrading our separation towers with high-efficiency structured packing and automated thermal control, we are pushing the boundaries of naphthalene extraction down to ppm levels, meeting the most demanding consumer product regulations worldwide.
As part of our commitment to carbon neutrality, we are researching the co-processing of biological and renewable hydro-treated pyrolysis oils with traditional heavy reformates to lower the cradle-to-gate carbon footprint of our solvents.
We are upgrading our refining loops with next-gen catalysts that select for aromatic retention while eliminating trace reactive olefins and sulfur species, yielding solvents with exceptional UV stability, low odor, and minimal color aging.
How Aromatic Solvent S-150ND serves as a critical component in global industrial supply chains.
S-150ND is the solvent of choice for Emulsifiable Concentrates (EC) and oil-in-water emulsions (EW). Its high solvency ensures active pesticide ingredients (AI) remain fully dissolved under extreme temperature cycles without crystallization, all while complying with EPA and EU pesticide registration regulations.
With an ideal evaporation profile and high flash point, S-150ND allows for optimal flow and leveling in baking enamels, coil coatings, automotive primers, and protective marine paints. It produces bubble-free, smooth films while reducing safety risks in high-temperature curing lines.
S-150ND serves as a high-efficiency carrier for drag reducers, corrosion inhibitors, and paraffin dispersants in upstream oilfield production. Its high aromatic density and low pour point keep chemical packages fluid and stable under cold marine or subterranean conditions.
Operating out of Zibo's Qilu Chemical Industrial Park, Saier Chemical features advanced distributed control systems (DCS) to monitor every step of the distillation, separation, and storage processes. This level of digitalization guarantees chemical specification consistency from batch to batch.

The difference is naphthalene content. Standard S-150 contains 8-10% naphthalene, requiring carcinogenic hazard classification labels. S-150ND (Naphthalene Depleted) reduces naphthalene to less than 1% (or under 0.1% for ultra-grades) through advanced extraction, avoiding carcinogenic warnings while maintaining solvent performance.
We offer multiple packaging options to match your logistics setup: 200L Steel Drums (80 drums per 20' FCL), Flexitanks (up to 24,000 liters), and ISO Tanks for continuous bulk supply contracts.
Our facilities are connected to and located within the Qilu Chemical Industrial Park, allowing us to source key reformate components directly from refining giants like Sinopec and PetroChina, securing production even during global raw material shortfalls.
Yes. The removal of naphthalene does not alter the core parameters like flash point (typically >63°C), boiling range (180-210°C), and high Kauri-Butanol value. It provides the same paint flow, leveling, and viscosity control.
Whether you require ISO Tank contracts, tailored naphthalene specs, or sample batches for agrochemical formulation testing, our technical sales engineers are ready to assist you.
