Low density polyethylene, or LDPE for short, is a compound in the polyethylene branch of thermoplastics. It is soft, light, hard and flexible by nature. This thermoplastic material also has low temperature compatibility and good corrosion resistance. The polymer also has good chemical properties and impact resistance, making it easy to handle and manufacture.
The structure of low-density polyethylene is more branched rather than perfect rows, and therefore low-density. As such, it is generally preferred in applications where structural strength and stiffness are important requirements.
Like other thermoplastics, polyethylene monomer is obtained using a process called polymerization, in which small molecules are removed and some are converted into the desired thermoplastic.
Currently, two methods are commonly used for the production of LDPE: agitated autoclave or tubing. However, later methods have become more popular due to their high ethylene conversion rates. Today, LDPE plastic is extracted from gaseous ethylene under very high pressure and high temperatures of up to 350 degrees, with catalyst oxide initiators in the presence. This process creates a polymer structure with both long and short branches. The polymer has shorter branches in low density polyethylene.
Low density polyethylene has a wide range of properties. The properties of high-density polyethylene and low-density polyethylene differ in some similar applications in several points. The key features are:
Low density polyethylene plastic is recyclable plastic. However, recycling is completely safe for human consumption. It is not as common and easy as other thermoplastics in applications.
Our organization also provides LDPE low density polyethylene analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
