WebSep 24, 2024 · Polyvinyl chloride (PVC) polymers are one of the most widely-plasticized types. PVC is usually is not very crystalline and is relatively brittle and glassy. The properties of polyvinyl chloride can be improved by blending it with substances of low volatility which tend to break down its glasslike structure. 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.
