HL high temperature resistant synthetic heat transfer oil

HL high temperature resistant synthetic heat transfer oil

Product description

Product composition

It is refined from high temperature blending of base oil synthesized chemically with a certain proportion of additives such as high-efficiency compound.

Performance characteristics

1. High heat transfer performance: It has high density, specific heat, thermal conductivity, and high heat transfer efficiency. It is a heat transfer medium with excellent performance.

2. Good thermal stability: It has outstanding thermal stability, and can be used for a long time in the highest temperature range (320℃) with a stable structure.

3. Strong anti-oxidation ability: high-efficiency antioxidants are added in the production and refining process to significantly improve its anti-oxidation ability. When it is exposed to air at normal temperature, the oxidation of the heat transfer oil slows down, which has little effect on the performance of the oil quality, so it can be used for a long time under normal operation.

4. Low vapor pressure: It has good low vapor pressure characteristics, which can be operated safely and reliably.

5. Non-toxic, odorless and non-corrosive: It has the non-toxic and odorless characteristics, especially is not corrosive to the equipment, requiring no anti-corrosion measures.

6. Good flow properties: It has the characteristics of low pour point, low viscosity, good pumping ability, and its pipelines and equipment are not easy to be blocked, which are especially suitable for use in severe cold areas for four seasons.
