The substance must be solid and non-compressible to prevent compression forces from moving it. Often, this product is used to fill large voids in pipe and wall structures. The most expensive type of structural foam is epoxy, and it works best for smaller ...
The dielectric constant of a polymer sample varies depending on the foaming concentration. Hence, the dielectric constant of foamed polypropylene samples was determined by taking measurements on the density of a polymer sample and its porosity. The result...
This process allows the polymer to become stiffer by adding an extra layer of elastomer. High-density polyethylene (HD-PE) is crosslinked to improve creep resistance. LD-PE is crosslinked to reduce creep performance but increases ductility. The resulting ...
