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
