Polyethylenes (PE)

It is the most widely used and widely used polymer around the world. Polyethylene comes in two main forms: Low Density and High Density. The difference lies in their structures which modifies their mechanical (resistance) and physical characteristics (melting temperatures: the high density PE melts at 135° C while the low density melts at 115° C).

In what form is this material found in the house?

Polyethylene is used in the manufacture of many products: Flexible hoses, electric cable ducts, toys, milk cans, basins, food preservation boxes, septic tanks.

How to recognize this material:

Polyethylene is easily scratched on the nail. A candle odor emerges from this plastic when a flame is passed on its surface. This smell is logical since polyethylene is part of the family of polyolefins in which we can "associate" the candle wax. In this sense, polyethylenes maintain the flame when burned and flow once melt.

How to work and tinker with this material:

Polyethylene is almost impossible to glue because it remains inert against the different glues available on the market. It is a relatively flexible material so easy to drill, mill or cut.
