Molecular structure of plastics
There are two basic types: the first is a linear structure, with the structure of polymers known as linear polymers; the second is the body structure, combined with the structure of the polymer is known as shape polymers. Some polymers with branched-chain called branched-chain polymer, which belongs to the linear structure. Some of the Intermolecular Crosslinking of polymer, but less cross-linking, known as the reticular formation, which belongs to the body structure.
Two different structures, showing two opposite properties. Linear structure, heat can melt, the hardness and brittleness minor characters. Hardness and brittleness of the larger body structure. Polymer plastic structure has, made of linear polymers are thermoplastic body is made of polymer thermoset plastics.
1 chemical resistance
2, gloss, partially transparent or translucent
3, most of the good insulator
4 light weight and sturdy
5, easy to be mass-produced, cheap
6, wide range of uses, effectiveness, easy coloring, of the excess heat
