Description
Chemical Name: 3-Ethoxyperfluoro(2,4-dimethylpentane)
Other Name: Perfluoroheptyl ether, Ethyl perfluoroheptyl ether
Equivalent Product: 3M Novec HFE-7500
CAS No: 1032934-86-3
TPD-HFE-7500 is a nonflammable fluid with very low global warming potential for use in heat transfer applications. TPD-HFE-7500 fluid shares many of the inertness and dielectric properties of perfluorocarbons (PFCs) and perfluoropolyethers (PFPEs), and is a viable option for replacing them in a wide array of applications.
Features

Application
- It can be used in cooling of ion implanters, dry etchers and CVD machines in semiconductor and flat panel display manufacturing facilities.
- It can be used to cool semiconductor thermal shock and test equipment.
- It can be used in direct contact single- and two-phase cooling of supercomputers and sensitive military electronics, and to cool high voltage transformers and power electronics.
- It can be used as an alternative to commonly used fluids in pharmaceutical and chemical manufacturing processes, such as freeze drying and reactor cooling.
Note:
1. Hydrofluoroether is a volatile substance, which decomposes at high temperature, and its main decomposition products are toxic hydrogen fluoride and fluorocarbon organic compounds.
2. Avoid splashing into eyes and contacting skin during operation. Please wear protective gloves, gas masks and glasses when using.
3. After use, the container should be closed in time to avoid volatilization. Please wash your hands after operation.
Packing
N.W.25KG or N.W.250KG Plastic drums.
Transportation & Storage
1. Transported as non dangerous goods.
2. It should be stored in a clean, dry and ventilated warehouse.
3. Keep the container closed to prevent high temperature and sunlight, away from heat source, fire source and strong alkali.
