Polyethylenes are a group of thermoplastics that are produced from ethylene gas stains. If instead of hydrogen atoms in polyethylene, a long chain of ethylene is bonded to carbon atoms, due to the fact that due to the occupancy of its greater density it decreases It is called polyethylene or polyethylene.
If there is no branched polyethylene molecule, it is referred to as a linear polymer, which is more resistant to the branched polyethylene.
If the density of polyethylene is in the range between the polyethylene (linear) and linear (PE) density, it refers to medium or semi-heavy polyethylene.
There is another type of polyethylene that is known as heavy polyethylene and is highly resistant and has a difficult processability.
Polyethylene is widely used in the plastics industry, which is used in most plastic kitchenware, disposable containers, plastic bags, pipes and fittings, and so on.
