WebCrystalline materials have highly defined and repeatable arrangements of molecular chains. These materials tend to have sharp melting points. Some of the common examples are diamonds, table salt, ice, sugar, and most metals. Crystallinity refers to the degree of structural order and regularity in molecular arrangements of a plastics material. WebAs mentioned, amorphous polymers are random, entangled chains, while semi-crystalline polymers are structured. The difference in molecular structure provides unique advantages for both. For example, amorphous polymers are transparent, experience no-to-low amounts of shrinkage, and offer superior low-temperature performance, high impact and …
