Benzyl Toluene is consist of Monobenzyl Toluene and Dibenzyl Toluene, they are both widely used on High temperature Heat Transfer Fluid and Dielectric oil, they have very goods low temperature ability. Both of our product RFCTHERM-MBT and RFCTHERM-340 are sold to USA, Korea, Japan, Europe and Russia. The mixture of both product RFCTHERM-330(M/DBT) can be used on capacitor oil, it is the same with the Jarytherm BT06 from Europe.
Monobenzyl Toluene（單芐基甲苯）
CAS #: 27776-01-8
Product Description
Monobenzyl Toluene(RFCTHERM-MBT) is a synthetic Heat Transfer Fluid with great flowbility at low temperatures. It can be used between -30℃-360℃ with vapor pressure. It has great low temperature ability. It has very high purity, low pour point, great liquidity at low temperatures. It has great molecular stability and great heat conductivity. The product is also very friendly with the environment and equipment. It has very good safety and very low corrosion on the facilities. It can be used in the system which has both heating and cooling systems and is widely used worldwide. This product is equivalent to Marlotherm SH,

Dibenzyl Toluene（雙芐基甲苯）
CAS #: 26898-17-9
Product Description
RFCTHERM-340 has a single molecular structure and high purity, its main ingredient is Dibenzyltoluene(abbrev: DBT), it is a high temperature liquid phase heat transfer fluid with excellent thermal stability. RFCTHERM-340 was developed for use at temperatures up to 340℃ in liquid phase heat transfer systems, Very high resistance to oxidation as well as high resistance to sludge and fouling can result in a significant reduction in capital investment, and reduced utility and maintenance costs as compared with other pressurized systems using more volatile high temperature heat transfer fluids.its chemical equivalent to TOTAL Jarytherm DBT and SOKEN NeoSK 1400.
The Temperature Range for use
Liquid: -30℃ to 340℃
Applications
