What is another name for polyethylene (PIB)?
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, folders, etc.).
What are the three types of polyethylene (PIB)?
Polyethylene can be divided into several main types based on its density and molecular structure:
- Low-Density Polyethylene (LDPE)
- Linear Low-Density Polyethylene (LLDPE)
- Medium-Density Polyethylene (MDPE)
- High-Density Polyethylene (HDPE)
- Ultra-High Molecular Weight Polyethylene (UHMWPE)
What is the most commonly used polyethylene?
HDPE
High-density polyethylene or HDPE is a commonly used petroleum thermoplastic and the most used of the three polyethylenes for a wide range of applications. If you look at this plastic under a microscope, you would see that it has a linear structure with few branches lending to its optimal strength/density ratio.
polyethylene Applications
- Polyethylene is ubiquitous in consumer products. In its foam form, polyethylene is used in packaging, vibration damping and insulation, as a barrier or buoyancy component, or as material for cushioning.
- Polyethylene foam is most frequently seen as a packaging material. Polyethylene foam is buoyant, making it popular for nautical uses. Many types of polyethylene foam are approved for use in the food industry.
- Found in all types of packaging, polyethylene foam is used to wrap furniture, computer components, electronics, sporting goods, plants, frozen foods, clothing, bowling balls, signs, metal products, and more.
- Polyethylene, particularly HDPE, is often used in pressure pipe systems due to its inertness, strength, and ease of assembly.
