Description
Chemical Name: Perfluoro nonenyl trifluoroethyl ether
CAS No: 176374-86-0
Chemical Structure:
TPD-HFE-7160 has excellent heat transfer ability, good insulation performance, excellent environmental protection performance and high compatibility with various materials. At present, it is the liquid cooling working fluid used in the mainstream semiconductor dry etching, wafer testing, packaging testing and other semiconductor manufacturing processes, and it can also be widely used as engineering liquid to detect leakage, cold and heat shock test, insulation test, high temperature aging test and so on. Its high voltage shock resistance can also be used as a cooling medium for EMU traction transformers.

Transportation & Storage
1. Transported as non dangerous goods.
2. It is volatile, pay attention to the tightness of the product during storage and transportation.
3. It should be stored in a closed high-density polyethylene tank or tin tank with internal coating and placed in a clean, dry warehouse.
4. Keep the container closed to prevent high temperature and sunlight, away from heat source, fire source and acid, alkali, strong oxidants, etc.
5. Avoiding violent vibration during transportation and avoiding upside-down when stacking.
