Commodity introduction

Commodity use:

 

That isEthylene oxideThat isHFCRefrigerants,As the most widely used medium and low temperature environmental protection refrigerant, it has become a very effective and safe because of its good comprehensive performanceR12

ForSubstitute products are mainly used in the useR12Most areas of refrigerant include: refrigerators, freezers, drinking fountains, automotive air conditioning, central air conditioning, dehumidifiers, cold storage, commercial refrigeration

It can also be used in aerosol propellants, medical aerosols, insecticide propellants and polymers (plastics)

Foaming agent, magnesium alloy protective gas and so on

Commodity characteristics:

Because it completely does not destroy the ozone layer, is currently the world's most countries recognized and recommended the use of environmentally friendly refrigerants, but also the mainstream of environmental protection refrigerants, widely used in new refrigeration empty
