Product Features
It is a new colorless and transparent synthetic polymer material with a wide range of viscosities (from 5mPa.s to 5000000mPa.s), from highly liquid to heavy simi-solid. This product has special smoothness, softness and hydrophobic, good chemical stability, excellent electrical insulation and resistance to high temperature. With high flash point and low freezing point, it can be used for a long time at the temperature -50 ºC to 200 ºC; Low viscosity-temperature coeffecient, high compressibility, low surface tension, good hydrophobic and moisture resistance, low thermal conductivity.

Safe operation and storage
It will tend to degrade and volatilize with contact with high concentration of strong acid or stong base material and Lewis acid. 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 under high temperature for a long period of time.
-
This product is sealed and packed by 200L iron drum (net weight 195kg/barrel) or 50kg plastic drum. It should not be in contact with strong acid and alkali.
-
Store at room temperature in a cool, ventilated place;
-
Transport as non-toxic and non dangerous goods.
