This product is based on a hydrocarbon compound with good molecular stability and a uniform molecular structure. It is a high-temperature resistant heat transfer oil with excellent heat resistance and antioxidation properties. In a properly designed and normally operating system, it exhibits minimal cracking, coking, and carbon deposition, resulting in a long service life. It has a high ignition temperature (ignition point of 500℃), excellent corrosion resistance, and good antioxidant properties. It can replace traditional high-temperature silicone oil heat transfer oil (ignition point of 300℃) and ester-based heat transfer oil, with a service life of over 10 years.

Scope of Application

The heat transfer oil H15 has strong antioxidant properties and can operate in both open and closed liquid circulation systems. Under excessive load conditions, it can maintain its physical parameters for a long time. Under normal pressure, the initial boiling point of the heat transfer oil is higher than the maximum operating temperature of the equipment.

Precautions

This product should not be mixed with methyl silicone oil or fire-resistant oil systems. It may also have a certain impact on some seals made of chloroprene rubber. However, it is suitable for use in places where silicone-based, polytetrafluoroethylene, and fluororubber sealing materials are used.

Product Features

Synthetic pure hydrocarbon compound with a uniform composition.
High flash point, high boiling point, high autoignition temperature, and low pour point.
Good thermal stability and antioxidant properties with minimal corrosion to metals.
Non-toxic and non-irritating, with no adverse effects on operators.
Long-term, stable, and safe use with renewable utilization.
