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.

Direct mold samplingcan be used to identify the species of white mold. Types of direct sampling include tape lift, swab and bulk samples. These samples are collected by a technician and sent to a laboratory for analysis. The lab will first determine if the suspect growth is mold, and if so, what species of mold.
