DIPHYL®

Diphyl® consists of an eutectic mixture of diphenyl oxide and biphenyl. Diphyl® is a high temperature heat transfer fluid for the application in liquid and vapour phase. For example it is used as heat transfer fluid in the manufacture plant of fibres and plastics and in the chemical industry. Diphyl® is also used for production of solar process heat and electricity in concentrated solar power plants.
