Full description
The company focuses on the comprehensive utilization industry chain of aromatic hydrocarbons, researching, developing, producing, and selling special fine chemicals and high-end environmentally friendly new materials. Currently, its main products include trimellitic anhydride (TMA), trioctyl trimellitate (TOTM), vinyl toluene (VT), and durene. The industry segmentation of the company's main products is as follows: 1. Trimellitic anhydride (TMA) TMA is an important polymer organic compound that belongs to the high-end product category of the fine chemical industry. It is widely used in environmental plasticizers, high-end powder coatings, advanced insulation paints, advanced lubricants, and high-temperature curing agents to enhance its heat resistance, weather resistance, migration resistance, corrosion resistance, volatility resistance, and high temperature resistance. One of the main uses of TMA is for the production of trioctyl trimellitate (TOTM). TOTM is a non-toxic and environmentally friendly plasticizer with excellent heat resistance, migration resistance, and insulation properties. It is mainly used as a plasticizer for high-grade PVC wires and cables, and as a blending agent for advanced lubricating oils. With the increasing demand for environmental protection and the improvement of wire and cable standards, TOTM's proportion in the plasticizer industry continues to rise. The second use of TMA is for producing powder coating resins. The powder coating produced by TMA has the characteristics of strong adhesion, durability, corrosion resistance, good leveling, low pollution, easy coating, and rapid curing. It is mainly used in household appliances such as air conditioners, refrigerators, washing machines, and indoor decoration. With the upgrading of industries such as light industry and home appliances in China, the demand for advanced and environmentally friendly coatings will gradually increase, and some products have already replaced traditional solvent based coatings. The third use of TMA is for producing polyamide imide insulation paint. The polyamide imide paint made of TMA has excellent high temperature resistance, aging resistance and wear resistance. It is mainly used as the insulation material for Class F and Class H high-end motors, as well as high-end explosion-proof motors, overweight motors, air conditioners, refrigerator motors, wind turbines and new energy vehicle drive motors. With the increasing demand for explosion-proof performance in the motor industry, the usage of advanced insulation paint materials that can withstand high temperatures will maintain a high growth rate. In addition, trimellitic acid esters (TMT) made from TMA have excellent high and low temperature resistance, low high-temperature evaporation, low coking amount, and good compatibility with various additives. They are ideal new materials for synthesizing high-temperature chain oils, high viscosity compressor oils, and blending advanced lubricating oils. During the reporting period, due to the permanent closure of production lines by American TMA manufacturers, there was a significant increase in demand for Chinese TMA in overseas markets, resulting in a significant rise in product prices. 2. Trioctyl trimellitate (TOTM) TOTM product is a heat resistant and durable plasticizer, which has the characteristics of high temperature resistance, aging resistance, corrosion resistance, migration resistance, and excellent insulation performance. It is mainly used as the main plasticizer of 105 ℃ heat resistant PVC wires and cables, and as the supporting plasticizer of 6kV and 10kV high-voltage PVC cables. It has irreplaceable advantages in improving the heat resistance and electrical insulation of wires and cables. In the future, with the development of power grid construction, 5G communication, rail transit, new energy vehicles, big data centers, artificial intelligence, industrial Internet and other fields, the rapid development of wire and cable industry will be directly or indirectly boosted, and the demand for TOTM will be driven by the development trend of new national infrastructure. At the same time, TOTM, as an environmentally friendly plasticizer, has the characteristics of high plasticizing efficiency, good processing performance, good compatibility, and migration resistance. With the improvement of environmental requirements and the change of consumer concepts, there is a huge demand for environmentally friendly non ortho benzene plasticizers in the automotive and pharmaceutical industries, which will further expand TOTM's market field. 3. Vinyl toluene (VT) VT is one of the raw materials for producing high-end insulation impregnating paint and is a high-performance and environmentally friendly new material. High end insulation impregnating paint produced with VT can be used in fields such as wind turbines, rail transit traction motors, industrial high-voltage motors, new energy vehicle drive motors, air conditioning motors, etc. 4. Durene Durene is the main raw material for producing pyromellitic acid, pyromellitic dianhydride, while pyromellitic dianhydride is the main raw material for producing polyimide polymers (PI). The polyimide molecule obtained by the oxidation of toluene to obtain phthalic anhydride (dicarboxylic acid) and the condensation with diamine contains highly stable aromatic heterocyclic structural units. Polyimide, as a special engineering material, has unparalleled high temperature resistance, excellent mechanical and electrical properties compared to other polymer materials. It has a wide range of applications in aerospace, electrical insulation, atomic energy industry, satellites, nuclear submarines, microelectronics, and other fields.
