Bisphenol A

Bisphenol A is mainly used in the production of epoxy resin and PC, accounting for 47% and 49% respectively, and the remaining 3% is used in other fields. The product has a narrow application, and its market is mainly distributed in Shandong, Jiangsu, Shanghai, Guangdong.

Polycarbonate (PC)

PC(polycarbonate), one of the five general engineering plastics, has good light transmission and impact resistance. The annual consumption of PC materials is about 5 million tons, of which China accounts for nearly half. The main downstream applications are electronic appliances, plates and automobiles, which account for about 80% of polycarbonate consumption. However, due to high technical barriers and other reasons, China's PC material industry is small in scale and long-term dependent on imports, which is still blank in Henan Province.

Logic rules for PC brand naming

The PC of our company has been successfully put into production, and now we need to name the product brand. It is suggested that the logic of naming trademark rule is as follows: trademark: 1. "S" represents "SHENMA". 2. "PC" is the English abbreviation of our polycarbonate product. 3. "10" refers to the melt index, which can be a natural number of 01-99, depending on the melt index of the products produced by our company. A melt finger includes a range, for example, the range of 10 melt fingers is 9.5-10.5. 4. "0" is our company's classification of product colors, which can be a natural number of 0-9. If the product has no color added, c is 0, if the product has blue added, c is 1, if the product has purple added, c is 2, and so on.

What material is polyurethane

The full name of polyurethane is polyurethane, which is a kind of macromolecular compound. Its main raw materials include diphenylmethane diisocyanate, toluene diisocyanate, polypropylene glycol, etc. Polyurethane has the characteristics of oil resistance, abrasion resistance, low temperature resistance, aging resistance, high hardness, elasticity, etc. It can be made into polyurethane plastic, polyurethane fiber (spandex), polyurethane rubber and elastomer.

Characteristics of polyurethane products

1. No scratch or noise. Long service life and reduced cost.2. The temperature resistance is from - 20 ℃ to 120 ℃.3. Polyurethane products are pollution-free, non-toxic and tasteless.

Function of polyurethane

Polyurethane can be used to manufacture plastics, rubber, fiber, rigid and soft foam plastics, adhesives and coatings, etc. It can be used in various fields of people's life, with a wide range of applications.

What is polyurethane

The full name of polyurethane is polyurethane, which is the general name of macromolecular compounds containing repeated carbamate groups on the main chain. Polyurethane is an imported group of urethane containing ether ester urea biuret urea based polyurethane at home and abroad. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds.

Overview of PU development

As early as the 1930s, polyurethane (PU) was developed by German scientists. German scientists condensed liquid isocyanate and liquid polyether or glycol polyester to form a new material. The physical property parameters of this material are different from those of polyolefin materials at that time. Scientists named it polyurethane. With the end of the Second World War, the chemical manufacturing industry in the United States flourished, and in the 1950s, polyurethane flexible foam was synthesized, which was an important landmark research in the chemical industry at that time and provided a solid technical foundation for the future development of the polyurethane industry.

Polyurethane

Polyurethane (PU), full name of polyurethane, is a kind of macromolecular compound. It was made by Otto Bayer in 1937. Polyurethane is divided into polyester type and polyether type. They can be made into polyurethane plastic (mainly foam plastic), polyurethane fiber (called spandex in China), polyurethane rubber and elastomer.

What is Polycarbon

Polycarbonate (PC for short) is a polymer containing carbonate group in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic aromatic and other types. The application of aliphatic and aliphatic aromatic polycarbonate in engineering plastics is limited due to their low mechanical properties.

Classification of chemical industry

We divide the chemical industry into three categories: petrochemical industry, basic chemical industry and chemical fiber industry.The basic chemical industry is divided into nine categories: chemical fertilizer, organic products, inorganic products, chlor alkali, special chemicals, pesticides, daily chemicals, plastic products and rubber products.

Definition of chemical industry

The chemical industry includes industries engaged in engineering design, daily chemical industry, energy and power, technology development, production technology management and scientific research in chemical industry, oil refining, metallurgy, energy, light industry, petrochemical industry, environment, medicine, environmental protection and military industry.
