In the global industrial chemical landscape, high-boiling aromatic solvents serve as foundational vehicle fluids for a vast spectrum of applications, ranging from agricultural emulsifiable concentrates (EC) to high-performance surface coatings, adhesives, and printing inks. Among these, Topsol A150 (equivalent to Aromatic Solvent S150 / Solvent Naphtha, CAS No. 64742-94-5) stands out due to its superior solvency power, controlled evaporation profile, and high flash point.
The term "Tanpa Merk" translates directly to "unbranded" or "private label". In global B2B procurement pipelines, purchasing Topsol A150 Tanpa Merk allows multinational blenders, regional distributors, and large-scale industrial end-users to source raw materials free from the margin premiums associated with big-brand packaging. It allows local chemical blenders to import bulk quantities, formulate under their proprietary brands, or adjust critical parameters (such as naphthalene levels) to meet strict regional environmental laws.
Shandong Saier Chemical Technology Development Co., Ltd. has established itself as a premier global manufacturer and exporter of unbranded Topsol A150. By offering raw, high-purity chemical streams, we empower global supply chains to maintain competitive cost structures without compromising on safety, density, or distillation accuracy.

Founded in December 2004, Shandong Saier Chemical Technology Development Co., Ltd. has embarked on an impressive journey over two decades. Located at No.207, WeiLiu Road, Qilu Chemical Industrial Park, Linzi, Zibo City, Shandong Province, China, our refinery-integrated facilities occupy the strategic heart of China's chemical manufacturing zone.
Initially founded with a registered capital of 60 million yuan, Saier Chemical secured its foundation through robust financial structuring and raw material partnerships with major global state refineries, including Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical. Today, our facility operates with an annual production capacity of 720,000 tons of aromatic hydrocarbon solvents (S-100, S-150, S-150ND, S-180, S-200), heat transfer oils (L-QC320), and downstream intermediates like durene, PVC plasticizers, thiophene, 1,3-Cyclohexanedione, and MIPK.
Topsol A150 Tanpa Merk is highly sought after by global formulation plants due to its chemical flexibility and lack of proprietary additives, making it an excellent carrier solvent. Below are the primary localized applications where our S150 solvent shows outstanding compatibility:
In Southeast Asia (e.g., Indonesia, Malaysia) and South America (e.g., Brazil), high-boiling aromatic solvents are critical for dissolving active ingredients (herbicides, insecticides, fungicides) in Emulsifiable Concentrates. Topsol A150 ensures excellent emulsion stability, high flash points for safe transport, and non-phytotoxic properties.
Automotive OEM baking enamels, anti-corrosive marine paints, and coil coatings require solvents with balanced evaporation rates to prevent surface defects like pinholing or orange peel. S150 provides high solvency for alkyd, acrylic, and epoxy resins, facilitating smooth flow and levelling during high-temperature baking.
In modern screen printing, ink formulation requires solvents that do not dry on the screen mesh but evaporate rapidly during the drying cycle. Unbranded Topsol A150 offers an optimal vapor pressure curve, ensuring consistent print runs on plastic, metallic, and textile substrates.
To ensure total quality compliance, Shandong Saier Chemical maintains modern fractionation, storage, and QA units in Qilu Chemical Industrial Park.
China's chemical manufacturing sector has shifted from basic scale expansion to advanced structural efficiency. Saier Chemical embodies this evolution through three main axes:
Our facility at Zibo is directly fed via pipeline and dedicated transport networks from major local petrochemical complexes, including Sinopec and PetroChina. This proximity minimizes raw material supply chain disruptions and transportation overheads, passing the cost savings directly to global buyers of unbranded Topsol A150.
Unlike traditional batch processing, Saier Chemical employs continuous distillation and separation technology. By automating temperature gradients and separation pressures, we maintain tight boiling point windows (184–205°C) and reduce organic impurities, ensuring batch-to-batch consistency.
As a national high-tech enterprise, we invest heavily in VOC gas capture, heat exchangers, and energy recovery systems. By lowering fuel gas requirements for our distillation towers, we reduce the carbon footprint of our aromatic solvents, aligning with global corporate ESG sourcing mandates.
For international procurement divisions, purchasing bulk chemicals requires absolute certainty in logistics, product classification, and customs documentation. Sourcing Topsol A150 Tanpa Merk from Saier Chemical is structured to meet rigorous procurement guidelines:
The Aromatic Solvent S100 is produced using crude C10 aromatics for industrial use as raw material and through continuous rectification for separation technology. It is a colorless, transparent, and aromatic organic solvent that complies with international standards for aromatic hydrocarbon solvents. It complements our Topsol A150 range by providing a lower distillation profile for formulations requiring faster drying times.
