Safety Organic Silicone Chemicals polydimethylsiloxane pdms
Dimethicone chemical name: poly two methyl siloxane;
Molecular formula is: (CH3) 3SiO [(CH3) 2SiO] n-Si (CH3) 3
The product is a colorless and transparent new polymer materials, a variety of different viscosities (5cps ~ 2million cps), the liquid from flowing easily into a thick semi-solid material. This product has a special smoothness, softness, hydrophobicity, good chemical stability, excellent electrical insulation and resistance to high temperature. High flash point, low freezing point, long-term using between -50 ºC ~ +200 ºC, low viscosity- temperature coefficient, high compression ratio, low surface tension, water-repellent moisture resistance, low heat conduction coefficient.

4. Textile, apparel industry as a softener, water repellent, feel modifiers, sewing thread lubrication, chemical fiber spinneret pressure lubrication and clothing lining additives.
5. Add it to other additives in leather and leather chemicals industry, it can be used as softeners, water repellent, feel agents, defoamers, brighteners.
6. Pharmaceutical, food, chemical, paint , building materials industry as defoamers, lubricants, and other weather-resistant paint.
7. Other specific purposes and other new materials.
Dosage:
Depending on the application conditions, the concentration is from a few PPM up to 100% range.
Dimethicone(methyl silicone oil)Note:
With a high concentration of acid or alkali substances and Lewis acid has a tendency to degrade volatile exposure, the higher the temperature of the reaction is more obvious. Low concentration in contact with strong acid or alkali at high temperatures or prolonged action of the viscosity tends to become larger until cross -linked.
