Description :
Dimethyl cyclic siloxane (DMC) is a mixture of dimethyl cyclic siloxanes mainly composed of dimethyl dichlorosilane as the main raw material, which is synthesized by hydrolysis and then separated, cracked, and distilled to obtain a mixture of dimethyl cyclic trisiloxane D3, octamethylcyclic tetrasiloxane D4, decamethylcyclic pentasiloxane D5, and dodecylcyclic hexasiloxane D6. The molecular formula is [(CH3) 2SiO] n=3-6
[Purpose]:
Starting from one or several types of linear, cyclic, and chain siloxanes, under the action of catalysts, high molar mass linear or cross-linked polysiloxane products can be produced through equilibrium, addition, or condensation reactions, including silicone oil, silicone rubber, and silicone resin.

[Packaging and Storage]:
1. Packaging specification: 200KG/drum. High viscosity: 200kg/barrel.
2. The mixed ring of dimethyl siloxane should be waterproof, rainproof, moisture-proof, sun proof, and prevent impurities such as acid and alkali from entering during transportation.
3. The temperature of the storage site for dimethyl siloxane mixed ring should be between 20 ℃ and 40 ℃, and insulation and antifreeze measures should be taken when the temperature is below 17 ℃. Under the packaging, transportation, and storage conditions that comply with this standard, the shelf life of this product is 12 months from the date of production. Overdue inspection is allowed, and if the inspection results meet the requirements of this standard, it can still be used.
