Polyethylene is one of the most widely used thermoplastic polymers made from the monomer ethylene. This material is used in various industries due to its unique properties.

Characteristics and properties of polyethylene

– High chemical resistance: Resistant to many chemicals.
– Flexibility and mechanical strength: Depending on the type of polyethylene, it can be flexible or hard.
– Light weight: Reduces transportation costs and use in various industries.
– Excellent electrical insulation: Used in the electrical and cable industries.
– Moisture resistance: Suitable for packaging and piping.

Types of polyethylene

– Low-density polyethylene (LDPE): Flexible, suitable for packaging and plastic bags.
– Linear light polyethylene (LLDPE): Has better mechanical strength than LDPE, used in packaging films.
– High-density polyethylene (HDPE): Strong and durable, suitable for pipes and storage containers.
– Ultra-high molecular weight polyethylene (UHMWPE): Very durable, used in medical and industrial equipment.

Polyethylene applications

– Packaging: Production of plastic bags, protective films and storage containers.
– Construction: Use in water and sewage pipes.
– Medical industries: Production of medical equipment and prostheses.
– Automotive: Manufacture of automotive parts.
– Household products: Production of plastic containers, toys and kitchen utensils.

Polyethylene production process

Polyethylene is produced through the polymerization of the monomer ethylene. This process can be carried out under high or low pressure, which results in the production of different types of polyethylene with different properties.
