This is obviously due to the semicrystalline nature of PP whose deformation depends strongly on the strain rate and temperature. |
|
Because of their stereoregular chain microstructure, optically pure polylactides, poly and poly, are semicrystalline. |
|
Semicrystalline thermoplastics generally, with some exceptions, have an inferior thermoformability compared with amorphous thermoplastics. |
|
In particular, some papers reported the formation of a fibrillated structure that was induced by the crystals during the foaming of semicrystalline polymers. |
|
Because of its semicrystalline structure, SPS is inherently more dimensionally stable and warpage-free than alternative materials, thus requiring less reinforcement. |
|
These are amorphous and semicrystalline polymers, polymer blends, rubber-toughened polymers, composites, nanostructured polymers, and special forms and applications. |
|
Moreover, changes of the semicrystalline morphology of the PVDF may have occurred, and even a gradual variation of the morphology across the layer may develop during service. |
