Hfc-134a is internationally recognized as one of the main refrigerant working substances to substitute cfc-12. It does not contain chlorine atom, gives no bad effects against ozonosphere and has excellent safety performances, such as non-inflammability, non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. It is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself. As the substitute for cfc-12, it is often used in the refrigerating systems of auto air conditioners, commercial and industrial purposes, and as the vesicant, it is used to produce the heat-protective material made of rigid plastics, and also to prepare other blend refrigerants, such as r404a & r407c.
Hfc-143a can be used as a refrigerant to substitute r502. It does not contain the chlorine atom, give no bad effects against ozonosphere and has excellent safety performances, such as non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. And it is a colorless gas under ordinary temperature and a colorless & transparent liquid under the pressure of itself.
R410A is a colorless gas under ordinary temperature, and a colorless & transparent liquid under the pressure of itself, mixed by HFC-32 and HFC-125. And it is the substitute for R22, mainly used in the air conditioners and other refrigerating systems.
R407C is a colorless gas under ordinary temperature, and a colorless & transparent liquid under the pressure of itself, mixed by HFC-32, HFC-134a and HFC-125. R407C is the long-term substitute for R22, mainly used in the air conditioner and other non-centrifugal refrigerating systems.
R415b is an environment-friendly substitute for r12 in the refrigerators and freezers, etc. It has good environmental protection, no toxicity, non-combustibility, fast refrigerating speed and good energy-saving performance. Nearly no need to change parts, pipeline original refrigerator or icebox for original r12 and direct filling is enough.
