Amorphous and Semi-Crystalline Materials

Polymers are classified as

Thermoplastic

Thermoset

Thermoplastic polymers are further classified by the configuration of the polymer chains with

random state (amorphous), or

ordered state (crystalline)

Amorphous- Molecular structure is incapable of forming regular order (crystallizing) with molecules or portions of molecules regularly stacked in crystal-like fashion.

A - morphous (with-out shape)

Molecular arrangement is randomly twisted, kinked, and coiled
