Dimethicone (low viscosity)
[performance characteristics]
201 Dimethicone, chemical name polydimethylsiloxane, the molecular formula is:
(CH3)3SiO[(CH3)2SiO]n-Si(CH3)3,
This product is a colorless and transparent new synthetic polymer material with a variety of different viscosities (5 cps to 2 million cps), from extremely flowable liquids to thick semi-solids. This product has special slip, softness, water repellency, good chemical stability, excellent electrical insulation and high and low temperature resistance. High flash point, low freezing point, long-term use at -50 ° C ~ +200 ° C, small viscosity coefficient, large compression ratio, low surface tension, good moisture resistance, low thermal conductivity.
[use]
1,201-5 as a chain end capping agent for silicone polymers
2, 201-10 as a lubricant (elastomer or plastic and metal lubrication, spandex oil);
3, low temperature hydraulic oil;
4, insulating liquid (impregnated paper capacitor);
5, as a diluent for room temperature vulcanized silicone rubber (two-component, room temperature vulcanized silicone rubber elastomer);
6, improve the fluidity of the coating additives.
[Benefits, performance]
Very good thermal stability; low surface energy; high compressibility; weather resistance; good oxidation resistance; low freezing point; viscosity change is less than non-silicone oil; good resistance to long-term high shear; low combustion Heat; limited burning.
[Dosage]
Depending on the specific application and application environment, the dosage ranges from a few PPMs up to 100%.
[Precautions]
Contact with high concentration of strong acid or strong base materials and Lewis acid has a tendency to degrade and volatilize. The higher the temperature, the more obvious the reaction. A low concentration of a strong acid or a strong base is in contact with it or a tendency to increase in viscosity until crosslinking occurs under high temperature for a long period of time.
