we have two types 330 Heat Transfer Fluids, RFCTHERM-330A and RFCTHERM-330B, detail is below:
RFCTHERM-330A
Product Description
CAS #: 28299-41-4
RFCTHERM-330A is a mixture of Xylyl Ethers, it is a synthetic heat transfer fluid designed to meet liquid phase systems.RFCTHERM-330A has excellent thermal stability and Low Temperature Pumpability, It was developed for use at temperatures between -30℃ and 330℃, Low viscosity at exceptionally cold temperatures makes it to be an ideal fluid for extreme climates. It is miscible and interchangeable with other similarly constituted Xylyl Ethers fluids, such as: Diphyl DT
