1,1,2,2-Tetrafluoroethyl 2,2,2-trifluoroethyl ether | CAS 406-78-0

Product Description

Chemical Name: 1,1,2,2-Tetrafluoroethyl 2,2,2-trifluoroethyl ether

CAS No: 406-78-0

Chemical Structure:

1,1,2,2-Tetrafluoroethyl 2,2,2-trifluoroethyl ether (CAS 406-78-0 / HFE 347) is a new-generation environmentally friendly hydrofluoroether liquid. It is a clear, colorless and odorless liquid with outstanding comprehensive performance, serving as an ideal substitute for traditional high-pollution fluorinated solvents, trichloroethylene and other cleaning agents.

Combining low toxicity, non-flammability, excellent material compatibility and superior solvency, this product can function as a high-efficiency refrigerant, foaming agent, precision fluorinated cleaning agent, heat transfer medium and packaging leak detection liquid. It is compatible with most organic solvents and industrial materials, and its eco-friendly properties (zero ozone depletion potential and low global warming potential) make it compliant with global environmental protection standards, suitable for long-term large-scale industrial application.

Important Safety Notes

Highlight risk warnings and standardized operating specifications to guarantee user safety:

1. HFE 347 (1,1,2,2-Tetrafluoroethyl 2,2,2-trifluoroethyl ether) is volatile. It will decompose under high temperature, generating toxic hydrogen fluoride and fluorocarbon organics. Keep away from high-temperature environments strictly.

2. During operation, avoid liquid splashing onto eyes and direct skin contact. Wear chemical-resistant gloves, protective goggles and gas masks as required.

3. Seal the container immediately after use to prevent product volatilization. Thoroughly wash hands after finishing operation.

4. Operate in a well-ventilated workshop; use a fume hood for heating or large-scale operations.

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.
