Light polyethylene is a soft, flexible and lightweight plastic material that is included in the category of polymer raw materials. One of the reasons for the popularity of light polyethylene is its flexibility at low temperatures and high resistance to corrosion.

PET or polyethylene terephthalate (PET) and polyethylene are similar to each other, but they have differences such as different polymer composition, different properties and applications, which you should pay attention to when choosing as raw materials.

Applications of light polyethylene (LDPE)

Also, the use of light polyethylene is not suitable for applications where hardness, high temperature resistance and structural strength are required. Light polyethylene is used in plastic raw materials, and due to its good flexibility and low price, it can be used to make food and garbage bags, juice containers, adhesive coatings, water pipes and hoses.

Unlike heavy polyethylene, light polyethylene has a branching structure with long and short branches. LDPE light polyethylene is produced at a temperature of 80 to 300 °C and a pressure of 1000 to 3000 bar through a free radical polymerization process. One of the other models of light polyethylene is linear light polyethylene, which we will explain below.

Linear light polyethylene

It is a linear polymer with short branches and is generally produced by copolymerization with short chain alpha olefins such as 1-butene, 1-hexene and 1-octene. Linear light polyethylene has higher tensile strength than light polyethylene. It also has a higher resistance to impact and puncture. Linear light polyethylene is used to make cable caps, small packages, liquid containers, etc.

Linear light polyethylene has a melting point of 105 to 115 degrees Celsius and its density is 0.91 to 0.94. Also, this material has a good resistance to alcohols, dilute acids and bases and has a low price with good processability.
