Polyethylene (PE) is a thermoplastic polymer that is widely used in various industries due to its multiplicity, resistance and economy. This is a type of polyalfin that comes from the combination of ethylene monomers. Here are some of the structural features of this material:
Types of polyethylene:
Low-Density Polyethylene (LDPE): This type of polyethylene has less density and more flexibility than other types of polyethylene. It is typically used in applications such as packaging films, plastic bags and tubes.
High-Density Polyethylene (HDPE): Unlike LDPE, this grade has higher density and more hardness and resistance than LDPE. It is used in various applications including bottles, pipes, containers, and geomembranes.
Linear Low-Density Polyethylene (LLDPE): This polyethylene has a short–branched, long–branched structure that gives it a balance of the properties between LDPE and HDPE. It is often used in film applications such as stretch coating, agricultural films and liners.
Properties of polyethylene:
Chemical Resistance: Polyethylene is resistant to many chemicals, acids and bases, making it suitable for a wide range of applications.
Flexibility: Depending on the type of polyethylene, it can range from very flexible (LDPE) to hard (HDPE).
Toughness: Polyethylene has high impact resistance and hardness, making it suitable for applications requiring fatigue resistance.
