At the same time, the company has been stably exporting products to Japan including 1,3,5,7-Tetramethylcyclotetrasiloxane (D4H, CAS: 2370-88-9), Tetramethyldivinyldisiloxane (Vinyl Double Cap, CAS: 2627-95-4), and 4-Vinylepoxycyclohexane (CAS: 106-86-5).

Persulfate Business

Changda Industry and Trade is an authorized agent for several domestic persulfate production factories in China, with written authorization. The annual average total export volume of Ammonium Persulfate, Sodium Persulfate, and Potassium Persulfate is approximately 5,000 tons.

Organic Peroxide Business

The company has previously cooperated with Younaide (Shanghai) Company to sell organic peroxides, with production at Younaide's German factory. Main products include Benzoyl Peroxide, Methyl Ethyl Ketone Peroxide, tert-Butyl Perbenzoate, and others. Organic peroxides produced in the chemical industry are mainly used as polymerization initiators and catalysts for synthetic resins.

Other Businesses

Changda Industry and Trade also cooperates with several factories in China to sell products such as Potassium Monopersulfate, Ammonium Bisulfate, and Sodium Bisulfate.

• Potassium Monopersulfate compound salt (Potassium monopersulfate, Potassium monopersulfate hydrogen sulfate) is an excellent acidic oxidant that is stable, easy to use, and widely applicable. Its applications span oral cleaning, pool and hot spring water disinfection, printed circuit board etching agents, pulp bleaching, wool fabric anti-shrinkage treatment, and precious metal extraction. Potassium Monopersulfate compound salt is an important auxiliary agent in organic synthesis, capable of causing epoxidation of organic molecules with double bonds, and serves as a radical initiator for many polymerization reactions. Additionally, it can be used as an oxidant for sulfur-containing substances such as hydrogen sulfide in wastewater treatment, low-temperature oxygen-based bleaching agents for detergents, and oxygen supply agents in aquaculture.
• Ammonium Bisulfate is mainly used in analytical reagents, pharmaceutical industry, organic reaction catalysts, and OLED industry. Currently, the main customers are in Korea, supplied to Samsung and LG for use in the OLED industry. Additionally, it is the only one that meets the standards required for OLED applications regarding heavy metal content.
• Sodium Bisulfate is mainly used as a flux or disinfectant, and also in the manufacture of sulfates and sodium alum. It is also used in the production of toilet cleaners, deodorants, and disinfectants. Applications include the determination of bromine, iodine, copper, and titanium dioxide, mineral analysis, household cleaners (45% solution), extraction of metallic silver, reduction of alkalinity in pool water, pet food, and OLED industry. Currently, the main customers are in Korea, supplied to Samsung and LG for use in the OLED industry. Additionally, it is the only one that meets the standards required for OLED applications regarding heavy metal content.
