Elastomer - definition, properties and examples of elastomer

What is an Elastomer?


Elastomer materials are those materials that are made of polymers that are joined by chemical bonds, acquiring a final slightly crosslinked structure.

An elastomer we can assimilate to the following example, imagine that on a table we have a set of strings mixed, each of these strings it´s represent a polymer, we introduce a relatively small effort if we want to separate the strings each others, now began to make knots between each of the strings, we see that as more knots that we made more ordered and rigid becomes all the strings, the knots of the strings is representing the chemical bonds, with a certain degree knots, or chemical bonds, more strongly stress need to apply to the strings in order to separate them, also we can observed that when we stress the string the length and the size of the strings increase and when we left to apply the stress the strings return to the initial length.

The main characteristic of elastomer materials is the high elongation and flexibility or elasticity of these materials, against its breaking or cracking.

Depending on the distribution and degree of the chemical bonds of the polymers, elastomeric materials can have properties or characteristics similar to thermosets or thermoplastics, so elastomeric materials can be classified into:

Now that you know the elastomers, did you know that all the tires of any vehicle are made with elastomer materials?
