A melting point is generally a discrete temperature, indicating when a material transitions from the solid phase to the liquid phase. For example, the melting point of polypropylene, a crystalline polymer, is 175°C (347°F).
WebNov 26, 2024 · 13.2: Crystalline and Amorphous Polymers. In ceramics or metals, a crystalline solid comprises repeating unit cells that contain each of the component atoms in the material. Each unit cell is composed of one or more molecular units. In a polymer this is not possible; the molecules are chains containing potentially millions of formula units. WebThe T m of crystalline plastics occurs at a relatively sharp point going from solid to melt. It is the temperature at which melts softens and begins to have flow tendency (Table 1.8).They have a true T m with a latent heat of fusion associated with the melting and freezing process, and a relatively large volume change during fabrication. Crystalline plastics …
