Applications

1. Organic synthesis & fine chemicals

   Used as an important intermediate for coupling reactions, dechlorination functionalization and other chemical reactions.
2. Polymer materials

   Plays a key role in the synthesis of dyes, plastics, rubber and other polymers, improving material performance and stability.
3. Silane coupling agent

   Essential raw material for synthesizing silane coupling agents; used in optical fiber materials, silicone oil, polysilane and other products.
4. Rubber processing

   Used as a processing aid to couple inorganic fillers in halogenated rubbers (neoprene, chlorinated butyl rubber, etc.), enhancing physical and mechanical properties.
5. Antimold & deodorant finishing agent

   Used to synthesize quaternary ammonium cation-containing organosilicon compounds with antimold, deodorant, antistatic and surface-active functions.
