WebFluorine-containing polymers are, however, not suitable to serve as construction material due to poor mechanical properties (low strength and stiffness, strong creep under load). Crystallinity. High-performance plastics can be divided in amorphous and semi-crystalline polymers, just like all polymers. WebFor semi-crystalline polymers, as the temperature increases, the bonds between the polymer chains weaken to create a pliable solid and then a viscous liquid, which allows the plastic material to be shaped to produce parts. Amorphous plastics are used for applications where optical clarity is required since light is scattered by crystallites.
