Desiccant Films Made of Low-Density Polyethylene with Dispersed Silica Gel-Water Vapor Absorption, Permeability (H₂O, N₂, O₂, CO₂), and Mechanical Properties.

Silica gel is a well-known desiccant. Through dispersion of silica gel in a polymer, films can be made that absorb and desorb water vapor. The water vapor absorption becomes reversible by exposing such films to a water vapor pressure below that of the water vapor pressure during absorption, or by he... View More
