Discover our highly verified intermediates and solvent systems engineered for industrial precision and electronics manufacturing.
Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has established an impressive presence in the highly competitive chemical industry. Situated at No. 207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, the company is built on a solid foundation, originating with a registered capital of 60 million yuan. This robust capitalization enabled us to establish state-of-the-art facilities dedicated to chemical processing and synthesis.
Historically, Shandong Saier Chemical was anchored in the production of high-quality basic chemical products. The initial product portfolio featured environmentally friendly, high-boiling point aromatic solvents (including Solvent Naphtha, TOPSOL, KOCOSOL, Toluene Aromatic Hydrocarbon, and Solvesso equivalents) such as S-100, S-150, S-150ND, S-180, and S-200. Alongside these, we manufactured Heat Transfer Oils (L-QC320) and key intermediate compounds like Durene, PVC plasticizers, Thiophene, 1,3-Cyclohexanedione, MIPK, TMOF, TMOA, HPA, and TMG.
We sourced raw feedstocks from industry leaders including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, ensuring the raw material inputs remained ultra-consistent. Operating with an initial annual processing capacity of 720,000 tons, the products serve major industrial centers across Beijing, Shanghai, Tianjin, Hebei, Shandong, and Henan, and supply crucial raw materials to global markets spanning Europe, the Americas, Asia, and Southeast Asia.
As a pivotal polar aprotic solvent, N-Methyl-2-Pyrrolidone (NMP, CAS 872-50-4) is critical for demanding high-performance applications. We detail our precise manufacturing specifications below.
N-Methyl-2-Pyrrolidone (NMP) stands out due to its high boiling point (202°C), high flash point (91°C), low toxicity profile compared to halogenated solvents, and exceptional thermal and chemical stability. At Shandong Saier Chemical, our production utilizes advanced catalytic synthesis pathways reacting Gamma-Butyrolactone (GBL) with Monomethylamine (MMA) under precise high-pressure and high-temperature conditions to secure an exceptionally pure output.
| Specification Parameter | Electronic Grade (Battery / Semi) | Pharmaceutical Grade | Industrial Grade |
|---|---|---|---|
| Purity (by GC) | ≥ 99.90% | ≥ 99.80% | ≥ 99.50% |
| Moisture (Water Content) | ≤ 100 ppm (typically < 50 ppm) | ≤ 500 ppm | ≤ 1000 ppm |
| Color (APHA) | ≤ 10 | ≤ 15 | ≤ 25 |
| Free Amines (as Methylamine) | ≤ 5 ppm | ≤ 10 ppm | ≤ 30 ppm |
| Free Acid (as Butyric Acid) | ≤ 10 ppm | ≤ 20 ppm | ≤ 50 ppm |
| Metal Ions (Fe, Cu, Ni, Na, etc.) | ≤ 10 ppb each | N/A | N/A |
By controlling trace moisture and metal contamination, our electronic-grade NMP maintains the electrochemical stability needed for lithium-ion battery electrodes and wafer fabrication in semiconductor processing. Standard industrial solvents cannot match this level of low-conductivity output.
How our strategic location and vertical integration ensure supply reliability and price stability.
Our location in the Qilu Chemical Industrial Park, Zibo City, Shandong Province, places us in a world-class chemical manufacturing cluster. This provides direct pipeline access to key primary raw materials and utility lines, drastically reducing handling costs.
We leverage robust relationships with leading domestic petrochemical conglomerates like Sinopec and PetroChina. This direct upstream integration isolates our client network from sudden, volatile raw material cost fluctuations.
Our 720,000-ton annual throughput capability allows us to process high volumes efficiently. This production scale translates to significant economies of scale, keeping high-purity solvents accessible for global markets.
Ensuring cross-border compliance and specialized chemical logistics across five continents.
Global procurement of Methyl Pyrrolidone requires strict adherence to international safety, environmental, and customs compliance protocols. As an established exporter, Shandong Saier Chemical provides comprehensive regulatory support, guiding clients through complex regional frameworks:
We provide full REACH registration data and substance safety reports. N-Methyl-2-Pyrrolidone is classified as a Substance of Very High Concern (SVHC) in Europe, demanding strict exposure controls. We help clients implement downstream exposure scenarios to ensure audit compliance.
For North American buyers, we comply with Toxic Substances Control Act (TSCA) rules and EPA reporting requirements for imports of NMP. We assist with safety datasheets (SDS) aligned with OSHA GHS standards, alongside required hazard labeling.
Whether utilizing ISO Tanks (up to 24,000 kg per tank), IBC Totes (1,000 kg), or heavy steel drums (200 kg), we ensure packaging meets international transport regulations (IMDG, ADR, IATA) to prevent moisture ingress and contamination.
How high-purity NMP drives modern industry, from green energy to microchip manufacturing.
In modern battery production, NMP is the primary solvent used to dissolve Polyvinylidene Fluoride (PVDF) binders. This is essential for dispersing active cathode materials (like LFP or NMC) and carbon black conductive agents into a uniform slurry applied to aluminum collector foils.
In microelectronics fabrication, electronic-grade NMP serves as a high-performance stripping solvent for photoresists. Its low metal-ion content prevents contamination of silicon wafers during cleaning, etching, and strip operations.
NMP is widely used as a solvent for polyurethane, polyamide-imide, and epoxy resins. It is particularly valued in baking finishes and wire enamels, where it enables smooth, even coatings under high-temperature curing conditions.
Due to its high solvency power, NMP is used to dissolve active ingredients in crop protection products. It ensures stable formulations for emulsifiable concentrates (EC) and suspension concentrates (SC), improving field efficacy.

Key market forces shaping the production and application of Methyl Pyrrolidone.
The global N-Methyl-2-Pyrrolidone market is evolving rapidly, driven by two key trends: the expansion of the green energy economy and the demand for closed-loop solvent recovery systems.
1. Growth in Electric Vehicles (EVs): The global transition to lithium-ion batteries has significantly increased demand for electronic-grade NMP. This surge is driving the construction of high-capacity synthesis units and specialized purification lines globally.
2. Advanced Closed-Loop Recycling: Because NMP is a restricted substance in several jurisdictions, modern manufacturing facilities are increasingly adopting closed-loop solvent recovery systems. In battery manufacturing plants, NMP vapors are typically captured using exhaust gas scrubbers and recycled via distillation, achieving recovery rates of over 98%. Shandong Saier Chemical supports this circular economy model by providing purification services for recovered solvent streams, restoring them to electronic-grade purity.

The company has developed two core product lines: Aromatic Solvent (TOPSOL/Naphtha) and Fine Chemical Material. Our primary products include Aromatic Solvents (such as S100, S150, S150ND, S180, and S200), Low-naphthalene formulations for pesticides, intermediates, and Heat Transfer Oil L-QC320. Among these, Aromatic Solvent S100 (CAS No. 64742-95-6) is produced using crude C10 aromatics through a continuous rectification process. This results in a colorless, transparent organic solvent that meets international standards for aromatic hydrocarbon solvents.
