What are the categories of fine chemical products included ？

Fine chemical industry is closely related to people's daily lives, and it is as important as grain production, which is related to national security. Therefore, fine chemicals are one of China's pillar industries. At the beginning of the new century, fine chemicals were listed as one of the development priorities by the State Economic and Trade Commission. This is one of the good opportunities facing fine chemicals.

Fine chemical products include 6 product categories:

1. Pesticide: The broad definition of pesticide refers to a substance or mixture of substances used for the prevention, elimination, or control of diseases, insects, grasses, and other harmful organisms that harm agriculture and forestry, as well as for the purposeful regulation, control, and impact of plant and harmful organism metabolism, growth, development, and reproduction processes, or derived from organisms, other natural products, and the application of biotechnology, and their formulations.

2. Dyes: As dyes, they must be able to adhere a certain color to fibers and not easily peel off or discolor. Dyes are usually soluble in water, and some dyes require a mordant to allow them to adhere to fibers. Dyes and pigments absorb some wavelengths of light, so they appear colored.

3. Coatings (including paint and ink): Coatings, traditionally known as paints in China. The so-called coating is a kind of viscous liquid that is coated on the surface of protected or decorated objects and can form a continuous film firmly attached to the coated objects. It is usually made of resin, or oil, or lotion, with or without pigments and fillers, with corresponding additives, and with organic solvent or water.

4. Pigments: Pigments are substances that can dye objects with color. There are soluble and insoluble pigments, and there are differences between inorganic and organic pigments. Mainly used in industries such as coatings, inks, printing and dyeing, plastic products, papermaking, rubber products, and ceramics. With the rapid development of downstream industries, the demand for pigments continues to expand, and the development prospects of China's pigment industry are very broad.

5. Reagents and high-purity substances: Reagents, also known as biochemical reagents or reagents. The main purpose is to achieve pure chemicals for chemical reactions, analysis and testing, research experiments, teaching experiments, and the use of chemical formulas. Generally, it is divided into general reagents, high-purity reagents, analytical reagents, instrumental analytical reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion chromogenic reagents, etc. according to their purposes.
High purity substance refers to a substance with extremely low total content of various impurity elements. The materials generated by the synthesis of high-purity substances with other substances can be applied in optoelectronics and semiconductor technology (acoustics, nonlinear optical crystals are used to control near-infrared lasers, ionizing radiation detectors, etc.), and can also be used in the field of optical communication (medicine, communication, physical field sensors, etc.).

6. Information chemicals (including photosensitive materials, magnetic materials and other chemicals that can accept electromagnetic waves): photosensitive materials, magnetic recording and optical recording materials, electronic semiconductor materials, photosensitive lotion, liquid crystal materials, phosphors, degassing agents, photoresists, chemicals used for photography, photocopiers, cleaning agents, auxiliary materials for optical fiber communication, etc.
