R134a
R134a
R134ais internationally recognized as one of the main refrigerant working substancesto substitute CFC-12. It does not contain chlorine atom, gives no bad effectsagainst ozonosphere and has excellent safety performances, such asnon-toxicity, non-inflammability, non-explosive ability , non-pungency, andnon-corrosive ability. It is a colorless gas under ordinary temperature and acolorless & transparent liquid under the pressure of itself. As thesubstitute for CFC-12, it is often used in the refrigerating systems of autoair conditioners, commercial and industrial purposes, and as the vesicant, itis used to produce the heat-protective material made of rigid plastics, andalso to prepare other blend refrigerants, such as R404A & R407C.

性状用途：
HFC-134a是目前国际公认的CFC-12 的主要制冷工质之一，HFC-134a不含氯原子，对大气臭氧层不起破坏作用；具有良好的安全性能（不易燃，不爆炸，无毒，无刺激性，无腐蚀性）；在常温下为无色气体，在自身压力下为无色透明液体，是R12 的替代品。常用于汽车空调，商业和工业用制冷系统，以及作为发泡剂用于硬塑料保温材料生产，也可以用来配置其他混合制冷剂，如R404a和R407c等。
