sompthing i heard about hfc134
It is internationally recognized that HFC-134a is the first and ideal choice to replace freon (CFCs product). The product is featured with no damage to the ozonosphere (ODP=0)safe non-toxicity and non-flammable.
HFC-134a is the substitution of CFC-12 in refrigeration, polymer foaming, acrosol producing, etc., which is widely used in automobile air-conditioning, home applications, small fixed refrigerators, medium-temperature refrigerators in supermarkets and industrial refrigerators.
As the research carrying on, HFC-134a is to be used as carrier of pharmaceutical inhalation. HFC-134a could also be used in the acrosol productioin with its extreme limitation in toxicity and flammability.
