HFC-134a now is internationally recognized as one of the main refrigerant working substances to substitute CFC-12. It does not contain the chlorine atom, give no bad effects against ozonosphere and have excellent safety performances, such as non-inflammability, non-explosive ability, non-toxicity, non-pungency, and non-corrosive ability. And it is a colorless gas under ordinary temperatures 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 mixed refrigerants, such as R404A & R407C.
HFC-134a automobiles air-conditioner system are obviously superior to CFC-12 in unit refrigerantion quality and COP, It's exxhaust temperature tatio is slightly high than CFC-12, and it's relative slip temperature is 2, have a little effect on component part and circulatory system after revealing.

Product Description

It is a colorless gas under ordinary temperatures with slight fragrance, and a colorless & transparent liquid under the pressure of itself, easily soluble in oil but poorly in water. And it is mainly used in the refrigerating systems under high temperature conditions, thermostatic control switches, the intermediate of aerial propellant, and the important raw material for vinglidene fluoride. Use as refrigerant, intermediate, material.
