Overview
HEAT TECH Heat Metal Oil is an industrial oil catalogued as a heat metal oil. It is offered in ISO VG 32, ISO VG 46.
The specification table lists, for each grade, kinematic viscosity at 40 °C and 100 °C, viscosity index, pour point, flash point and acid number, each with its test method. Share operating conditions with our technical team to confirm the grade before supply.
Application
The intended process is confirmed case by case with our technical team before supply.
Feature
ISO VG 32: KV40 36 cSt, KV100 5.8 cSt, VI 101, pour point -24 °C; ISO VG 46: KV40 47 cSt, KV100 7.4 cSt, VI 100, pour point -21 °C.
Feature
Published kinematic viscosity at 40 °C sits inside the ISO 3448 tolerance (mid-point ±10 %) for ISO VG 46 (47 cSt).
Feature
Besides viscosity, the published data includes acid number, flash point (COC) and foaming tendency.
Start from the equipment manufacturer's viscosity recommendation at operating temperature. The ISO VG number is the mid-point kinematic viscosity at 40 °C (ISO 3448), and each grade's published values are listed separately.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
