Polyethylene
Polyethylene is chemically the simplest polymer. It is represented with its repetitive unit ₙ. It is one of the most common plastics due to its low price and simplicity in its manufacture, which generates an annual production of approximately 80 million tons worldwide, it is chemically inert.
Polymer prepared from ethylene.
"Polyethylene is used, among other uses, in the manufacture of packaging, pipes and cable coatings"
What is polyethylene and what is it for?
Polyethylene is a material that is used for different types of products, and in different processes, such as the following: 1. Extrusion. It is a system of heating and pressure of the material through a hole to manufacture cables, wires, pipes.
Polyethylene Properties
Polyethylene is chemically inert, that is, it is almost non-reactive, and has a whitish and translucent appearance. Tenacious and flexible at ordinary temperatures, it has a soft and rayable surface. ... Its viscosity decreases at a higher temperature, and a density of 0.80 at about 120 ° C.
PE, polyethylene
Polyethylene (PE) is one of the most widely used plastics in the world and is widespread in all industries, segments and applications.
Polyethylene is a vinyl polymer, made from ethylene monomer. Here is a model of the ethylene monomer. To be honest, it seems like a kind of toy bear of contemporary art. Branched polyethylene is made by means of a free radical vinyl polymerization.
Polystyrene. It is a transparent substance that withstands moderate temperatures (melts at about 85 ° C) and has very little resistance to chemical agents such as solvents in general.
How long does it take to degrade polyethylene?
Plastic bags and bottles
150 years is the time it takes for a common plastic bag to degrade and a PET bottle can take 1,000 years to disappear. Let's recycle these materials correctly and, whenever possible, replace them with other biodegradable ones such as paper bags or cloth.
