Thermoplastics and Thermo-setting bonding wire

Thermoplastics are made of giant molecules. (macromolecules) During the creation process, plastics are standing a plastic step, property to be distorted at anytime. Macromolecules are chains of many either similar or different basic molecules.
Substances constitued with basic molecules are called "monomers".
Substances constitued with macromolecules are called "polymers".
"Polymerization" is the transformation where monomers are combining together.
Monomers are generally structured with carbonated base, when polymerizing they combine together to make "carbonated chains".
During polymerization molecules are gathering together to make linear or ramified chains and in some cases transversal links providing a tridimensional network called "reticulation".
From the processing industry view we can separate the thermoplastics from the thermo-setting bonding substances.
Thermoplastics are plastics (homopolymers, heteropolymers or polycondensation products) whom shape can be modified many times under action of increasing heating or pressure.
They are obtained through a chain shaped polymerization with a linear structure more or less ramified, just set side by side or mixed up, without reticulation.
This action can be reverted and reproduced.
Examples : ABS, PVC, Nylon, Perlon, Rilsan, Macrolon, PET.
