Additives include antioxidants, anti-wear agents, detergents, and dispersants, which are used to improve the performance of lubricants.
    - Different application scenarios have different performance requirements for lubricants. For example, automotive engine lubricants need to maintain good lubrication and cleaning performance under high-temperature and high-load conditions, while industrial gear oils need to have higher load-carrying capacity and anti-wear performance.
- Supplier Role
    - chemical suppliers need to provide high-quality base oils and additives. For base oils, chemical suppliers must ensure that their viscosity index, flash point, and other indicators meet the requirements of the lubricant formula. For additives, chemical suppliers need to ensure the content and dispersibility of the active ingredients to fully utilize the function of the additives.
    - At the same time, chemical suppliers need to develop new types of additives based on the development trends of the lubricant industry. For example, with the increasing demand for environmentally friendly lubricants, chemical suppliers need to adjust their product formulas in a timely manner and provide low-sulfur, low-phosphorus additives that meet environmental requirements.

(4) Oil Fields and Water Treatment
- Demand Characteristics
    - The oil field exploitation process requires a large number of chemicals, such as drilling fluid additives (viscosity enhancers, filtration loss reducers, etc.), demulsifiers, and scale inhibitors. These chemicals are used to optimize drilling processes, improve oil extraction efficiency, and prevent equipment scaling.
    - In the water treatment field, flocculants, biocides, and scale inhibitors are needed. For example, in industrial circulating water systems, scale inhibitors are used to prevent the formation of scale, and biocides are used to inhibit the growth of microorganisms.
- Supplier Role
    - chemical suppliers need to provide chemicals that are suitable for oil field and water treatment processes. For oil field chemicals, chemical suppliers need to provide customized chemicals based on different geological conditions and exploitation processes. For example, for high-salinity oil reservoirs, chemical suppliers need to provide drilling fluid additives that are resistant to high salinity.
    - In the water treatment field, chemical suppliers need to provide efficient and environmentally friendly chemicals. For example, developing new biodegradable flocculants to reduce environmental impact.

II. Pharmaceuticals and Food
(1) Pharmaceuticals
- Demand Characteristics
    - The pharmaceutical R&D and production process has extremely high requirements for the purity and quality of chemicals. For example, in the process of drug synthesis, the purity of raw materials and intermediates directly affects the quality and efficacy of the drugs.
    - The pharmaceutical industry also requires a large number of reagents and solvents, such as high-purity ethanol and acetone, which are used in drug extraction and purification processes.
    - At the same time, the pharmaceutical industry has strict compliance requirements for chemicals, and chemical suppliers need to provide chemicals that meet Good Manufacturing Practice (GMP) standards.
- Supplier Role
    - chemical suppliers need to provide high-purity, high-stability chemicals and ensure that their products meet the quality standards of the pharmaceutical industry. For example, for raw materials, chemical suppliers need to provide detailed quality inspection reports, including purity, impurity content, and other indicators.
    - chemical suppliers also need to work closely with pharmaceutical companies and provide customized chemicals based on the needs of drug R&D and production. For example, for the synthesis of some new drugs, chemical suppliers may need to develop and provide special intermediates.
