As a core category of heavy lubricant base oil, 150BS bright stock is reputed as the "golden raw material" in the high-end lubricant industry. It serves as an indispensable basic industrial material for multiple downstream sectors including iron and steel, chemical engineering, chemical fertilizer production, textile printing and dyeing, large-scale engineering machinery and marine shipping. In practical industrial scenarios, it is primarily adopted for blending high-end lubricants and greases, as well as routine lubrication for heavy-duty industrial equipment.
Despite robust domestic market demand for 150BS bright stock in China, over 20% of domestic consumption still relies on overseas imports. The product features long processing cycles, high production costs and rigorous technical barriers, resulting in a limited number of qualified domestic manufacturers. Current market competition mainly centers on technical iteration and finished product quality of high-end 150BS bright stock. Benefiting from mature proprietary processing technologies, Jingmen Petrochemical holds a prominent market share in the high-end superior-grade 150BS segment. Meanwhile, it maintains strong competitive advantages in medium-grade first-class and qualified-grade markets thanks to consistent product quality and cost-effective pricing strategies.
Jingmen Petrochemical classifies its 150BS bright stock into three independent grades with differentiated performance indicators and targeted application scenarios, covering full-spectrum downstream industrial demands:
Product Characteristics: Colorless, odorless, high viscosity, high flash point, outstanding photo-thermal stability
Application Scenarios: High-grade diesel engine oil, wind power gear oil, mining heavy-duty gear oil, high-temperature bearing grease, high-temperature resistant sealing gaskets, long-service-life conveyor belts, outer rubber claddings for power cables and other high-temperature endurance components
Product Characteristics: Colorless, odorless, high viscosity, high flash point, reliable thermal stability
Application Scenarios: Heavy-duty gear oil, marine cylinder oil, generator set lubricating oil, open gear grease, shock-absorbing rubber pads, industrial conveying crawler components
Product Characteristics: Slight pale yellow appearance, no pungent odor, high viscosity, high flash point, qualified thermal stability
Application Scenarios: Conventional heavy-duty gear oil, marine cylinder oil, generator set lubricating oil, open gear grease
Different from peer manufacturers, Jingmen Petrochemical builds differentiated core competitiveness via high-quality raw material supply and standardized whole-process raw material management systems, which underpin stable high-quality output of 150BS bright stock.
The enterprise prioritizes raw material allocation for special oil products such as 150BS bright stock. It realizes steady supply of three mainstream crude raw materials: paraffinic base stock, intermediate base stock and naphthenic base stock. By dynamically optimizing raw material blending ratios, Jingmen Petrochemical balances high viscosity index, absolute viscosity and high flash point simultaneously, ensuring all core performance indicators meet national and international standards from the raw material source.
In response to differentiated quality thresholds for superior, first-class and qualified 150BS bright stock, the enterprise optimizes segmented production workflows. It avoids over-processing for medium and low-grade orders to control production costs, delivering cost-tailored products that match customized usage requirements for different industrial clients.
Jingmen Petrochemical is the first refining and chemical enterprise alongside the Yangtze River in China with independent production capacity for high-end 150BS special lubricant base oil. Backed by decades of technical accumulation in special oil refining, it has established a closed-loop full-chain production system covering raw material pretreatment, catalytic core reaction, solvent refining and purification, and finished product third-party testing.
The production line boasts high automation and micron-level precise process control, supporting large-scale differentiated batch production of the three 150BS grades. In addition, the facility supports flexible capacity adjustment and product structure rearrangement. The enterprise can adjust the output proportion of three grades in real time according to domestic and overseas market demand fluctuations, significantly improving market responsiveness and order fulfillment efficiency.
