Hydrogenated synthetic heat transfer oil
Product composition
It is a kind of high-carbon chain stable heat transfer oil made from linear chain saturated alkane or naphthenic base oil after refining and hydrogenation. The base oil as the main raw material of the product is made in reduced pressure distillation and secondary cutting, saturated hydrogenation reduction on the base of large-scale petrochemical industrial process. It is made by adding different proportions of antioxidants, anti-coking agents and other additives after high temperature blending.
Performance characteristics
It has oxidation resistance, high thermal stability, good heat transfer performance, high enthalpy, large heat transfer, and good heat transfer efficiency. It has narrow distillation range, low vapor pressure, high flash point and high spontaneous ignition point.
