Advantages and applications of high density polyethylene (HDPE)

Advantages and applications of high density polyethylene (HDPE)

High density polyethylene is the highest production synthetic polymer in the world. It has the characteristic of being colorless, odorless, non-toxic and obtained at low pressure.

This polymer belongs to the class of unbranched straight chain polymers and is less ductile than low density polyethylene, although it is stronger, harder and four times less permeable. Due to its physical and chemical composition, it is extremely resistant to blows and chemical products.

High density polyethylene, when recycled, has a fairly regular quality and the recycling process is mechanical. It can only be reused by extrusion processes and when its presentation is in large pieces, press molding is used.

Characteristics of high density polyethylene

The characteristics of high density polyethylene are the following:

High impact resistance
It’s very light.
It is flexible, even at low temperatures.
High chemical and thermal resistance.
It can not be attacked by acids.
Resists water at 100ºC

Applications of high density polyethylene

Due to its characteristics, high density polyethylene has the following applications:

– Household utensils

– Toys

– Bottles

– High-density polyethylene sheets previously manufactured

– Helmets, knee pads, elbow pads and other safety elements

– Food packaging, detergents and cleaning products

– In laboratories, it is usually used to contain acids, due to its high resistance to them

Advantages of high density polyethylene

High density polyethylene offers the following advantages:

– Elasticity

– It is not permanently deformed

– It is a recyclable product

– Easy to transport

– It has a quite long lifespan

– It is flexible

– It is resistant to any form of corrosion

– Its cost of acquisition and installation is extremely low

– It can be processed in large sheets, which reduces the need for other materials

– Resistance to seismic movements

– Resists acids, highly corrosive chemical elements and bacteria
