This process is experimental and the keywords may be updated as the learning algorithm improves.Ĭ. These keywords were added by machine and not by the authors. ![]() During the process of aging, polyolefins lose their elasticity, become brittle, crack, lose their mechanical strength, dielectric properties, in most cases change color, etc. However, just like most other high-molecular compounds, polyolefins are subject to oxidative-destructive processes under the influence of atmospheric conditions, increased temperature, light, aggressive media, and a number of other factors. These polymers possess high mechanical strength, low density, flexibility at low temperatures, high impact strength, moisture stability, splendid electrical insulation properties, and a number of other properties. Among polymer materials, polyolefins -polyethylene, polypropylene, and copolymers of ethylene and propylene - are acquiring special significance at the present time. ![]()
