LLDPE
Linear Low-Density Polyethylenee
Linear Low-Density Polyethylene (LLDPE) is a type of polyethylene known for its excellent combination of properties. It is a thermoplastic material similar to LDPE (Low-Density Polyethylene), but with a linear structure offering improved properties such as higher strength, stiffness, and toughness. LLDPE is known for its high impact resistance and flexibility, making it ideal for applications that require high durability and resistance to external forces. It also has excellent puncture resistance and tear strength which makes it suitable for applications that require a high level of toughness. LLDPE also has a high chemical resistance, proving ideal for applications that require resistance to chemicals and solvents. Additionally, its moisture barrier properties are effective for packaging materials. LLDPE is a lightweight, low-density material that is easy to handle and transport. It can be produced in a variety of colors and textures, as well as be blended with other materials to improve its properties.
LLDPE was first developed in the 1950s by a group of scientists at the Phillips Petroleum Company in the United States while attempting to create a new form of polyethylene that would have improved properties over traditional low-density polyethylene (LDPE). They discovered that by using a specific type of catalyst and high-pressure process, they were able to create a new polymer that had a linear structure offering higher strength, stiffness, and toughness compared to LDPE. Today, LLDPE is one of the world’s most widely used plastics and is produced in large quantities.
