WebBy definition, a crystalline solid, also simply known as a crystal, is a solid material whose basic constituents such as atoms, ions, and molecules are arranged in a highly ordered and well-defined microscopic structure, … WebCrystalline plastics have considerable order of the molecules in the solid state indicating that many of the atoms are regularly spaced. The melt strength of the plastic occurs while in the molten state. It is an engineering measure of the extensional viscosity and is defined as the maximum tension that can be applied to the melt without breaking.
