Product Description
Product description:
Perfluoropolyethers (abbreviated as PFPE), Juhua's JHT series PFPE products are perfluoropolyethers heat transfer fluids. They are dielectric fluids with current boiling points ranging from 135 to 270ºC. Their excellent dielectric properties, high chemical stability combines with the capacity to operate at very low temperatures as well as elevated temperatures make them the best heat transfer fluids for the aggressive conditions.
Their properties are as follows:
1.Compatible with most materials over a wide temperature range.
2.Thermally stable and chemically inert.
3. Excellent dielectric properties: high electrical resistivity and low dielectric constant.
4.Low viscosity.
5.No flash point, fire point or toxicity. This product is designed with environmental friendliness, your health and safety in mind. You can use it with peace of mind even at aggressive conditions.
6.No flash point, fire point or toxicity. This product is designed with environmental friendliness, your health and safety in mind. You can use it with peace of mind even at aggressive conditions.
