We're leading China R134a Refrigerant , R134a Gas, Refrigerant R134a, 13.6kg R134a Supplier & Manufacturer. We produce most kinds of refrigerant and already export to most of countries. Our quality already win a good reputation in oversea market. We can customize the R134a Refrigerant totally according to your requirements.
R134a Refrigerant also known as norflurane (INN), is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential. It has the formula CH2FCF3 and a boiling point of −26.3 °C (−15.34 °F) at atmospheric pressure. R134a Refrigerant cylinders are colored light blue. Attempts at phasing out its use as a refrigerant with substances that have lower global warming potentials, such as HFO-1234yf are underway.
Contact of R134a Gas with flames or hot surfaces in excess of 250 °C (482 °F) may cause vapor decomposition and the emission of toxic gases including hydrogen fluoride and carbonyl halides. Refrigerant R134a itself has an LD50 of 1,500 g/m3 in rats, making it relatively non-toxic, apart from the dangers inherent to inhalant abuse. Its gaseous form is denser than air and will displace air in the lungs. This can result in asphyxiation if excessively inhaled. This is what contributes to most deaths by inhalant abuse.

The valuable properties of lasers determine the advantages of lasers in the processing field:
1. Because it is non-contact processing, and the energy and moving speed of the high-energy laser beam are adjustable, it can achieve a variety of processing purposes.
2. It can process a variety of metals, non-metals, especially materials that can handle high hardness, high brittleness, and high melting point.
3. There is no "tool" wear during laser processing and no "cutting force" acts on the workpiece.
4. During the laser processing, the laser beam has a high energy density, a high processing speed, and a local processing, which has no effect on the non-laser irradiation site or minimal impact. Therefore, the heat affected zone is small, the workpiece thermal deformation is small, and the subsequent processing volume is small.
5. It can perform various processing on the workpiece in a closed container through a transparent medium.
6.Because the laser beam is easy to guide and gather, it can be changed in all directions. It is easy to cooperate with the CNC system and process complex workpieces. Therefore, it is an extremely flexible processing method.

Aerosol cans containing Refrigerant R134a, when inverted, become effective freeze sprays. Under pressure, Refrigerant R134a is compressed into a liquid, which upon vaporization absorbs a significant amount of thermal energy. As a result, it will greatly lower the temperature of any object it contacts as it evaporates. This can result in frostbite when it contacts skin, as well as blindness upon eye contact.
