  1. Synthesis of polysiloxane containing faculties end groups.

  2. Can be used for the preparation of high performance organic silicone surfactants.

  3. Applicable to the production of many products, such as addition silicon rubber, silica gel, Hydrogenpolysiloxane and plastic, resin modifier, dendrite polymer special additives, etc.

And listed are our advantages for TMDSO product:

  1. We keep good relationship with monomer factories, so we can manufacture 1,1,3,3-Tetramethyldisiloxane with stable raw material supply.  Thus we can guarantee 10-20 tons/month supply only to you (safety stock).

  2. Our purity reaches up to 99.3%, and can even reach up to 99.5%-99.8%, which is higher than other factories. And our Cl content is less than 5 ppm.

  3. We are one of the biggest raw material manufacturers for 1,1,3,3-Tetramethyldisiloxane in China, and our production capacity for 1,1,3,3-Tetramethyldisiloxane is 60 tons/month, and actual output is 40 tons/month.

  4. Business contingency plan: We will control the production and supply of products from every process, and we can guarantee supply 1,1,3,3-Tetramethyldisiloxane continuously.

Note: We have finished REACH Registration for 1,1,3,3- Tetramethyldisiloxane(TMDSO).
