Everything to know about Refrigeration Gas and Polyethylene

7 min read

Many chemical products and compounds are often used in day to day life, for example polythene or refrigerant gas. One helps in packaging-related requirements and the other is useful in keeping your food fresh and cool in summers. How about knowing a few interesting things about these two chemicals, which have both commercial and personal uses. First, we will tell you a little about the refrigerant gas, also known as refrigeration gas used in air conditioners and various industrial purposes.

Refrigerant gases have low evaporation points and are condensed under pressure to make the air cold. Through a process of evaporation and condensation, the heat is pulled out of the air and the temperature is reduced. The different types of refrigerant gases include chlorofluorocarbon (CFC), hydro chlorofluorocarbon (HFC), perfluorocarbon (PFC), and some blends made using ammonia and carbon dioxide.

What are Refrigerants?

A refrigerant is a substance that absorbs all the heat through vaporization or expansion and is applied to cooling systems. This includes all the working mediums that pass through the process of evaporation, recovery, compression and condensation.

What are the desirable properties of a Refrigerant?

The most desirable property of a refrigerant is that in case of any leakage, there is no danger to health or property of an individual. Although, substances such as butane, ethane and hexane have been used for refrigeration but these cannot be used as they are highly inflammable and explosive in nature.

The reason for Switching to Refrigerant Gases

Refrigerators in the 1800’s were built using toxic gases such as ammonia, methyl chloride, and sulfur dioxide. However, because of leakage it resulted in loss of many lives. This is when refrigeration industry started looking for a good alternative as a refrigerant gas. As a result, chlorofluorocarbon gas which is a mixture of chlorine, fluorine and carbon was used. This gas was colorless, odorless, non-inflammable and non-toxic.

What are the different types of refrigerant gases?

Depending upon the requirement and the system for which cooling is required, refrigerant gases can be classified into the four categories mentioned below.

  • R-134: The best option for vehicle air-conditioning, commercial and household refrigeration applications. The R-134 is a non-toxic refrigerant gas that is non-combustible and can also be used as aerosol and blowing agent.
  • R-11: Also known as Freon, a refrigerant that can be used in refrigerator and air-conditioning systems. This is also used in industrial refrigerant plants and chillers owing to its efficient cooling and non-toxic nature.
  • R-407: One of the refrigerant gases used in cleaning. It is completely non-toxic and non-combustible and widely used for air-conditioning systems.
  • R-404: Efficient in both refrigeration as well as cleaning, this gas offers advanced benefits owing to its non-inflammable and non-toxic contents.

There are many polyethylene supplier and refrigerant gas supplier for those looking to use either of these for industrial applications. Now, let us take a look at the polyethylene better known as polythene to the lay man.

The primary uses of polyethylene are that it is used for packaging with plastic films, plastic bags and water bottles. Polyethylene has low hardness, rigidity but high strength and low friction. It can be classified into two categories, namely low density and high density polyethylene:

Low-Density Polyethylene: This form of polyethylene has a melting point of 115 degree Celsius and can easily retain temperature over varying temperatures. However, the density drops when it goes above room temperature. Low-Density polyethylene is widely used in cling wrap, squeeze bottles, and liners for tanks and ponds.

High-Density Polyethylene: High-Density Polyethylene has a melting point of 135 degree Celsius and is much stronger than the low-density polyethylene. It is used while manufacturing
