Thermoplastic - definition, properties and examples of thermoplastic.

What is a thermoplastic?


Thermoplastic materials are those materials that are made of polymers linked by intermolecular interactions or van der Waals forces, forming linear or branched structures.

A thermoplastic material it can be compared to a set of strings that are mixed on a table, each of these string is represents a polymer, the greater degree of mixing of the strings greater the effort will be made to separate the strings from each other, due the friction that occurs between each of the cords offers resistance to separate, in this example the friction represents the intermolecular forces that holds together the polymer.

polymer structures

Depending on the degree of the intermolecular interactions that occurs between the polymer chains, the polymer can take two different types of structures, amorphous or crystalline structures, being possible the existence of both structures in the same thermoplastic material:

If the thermoplastic material has a high concentration of polymers with amorphous structures, the material will have a poor resistance to loads but it will have an excellent elasticity. But on the contrary, if the thermoplastic material has a high concentration of polymers with a crystalline structure, the material will be very strong and even stronger than thermoset materials, but with a little elasticity that provides the characteristic fragility of these materials.
