Abstract:

Carbon black has been found to be the most effective stabilizer for polyethylene plastic with respect to degradation due to light and weathering. This stability is very important when the material is subjected to exposure to sunlight and weathering over long periods of time such as in electrical cable sheathing applications and in plastic pipe. A study of the interrelation between the plastic and the carbon black surface is important so that future increases in stability may result. For example, the distribution of the carbon black surface within the polyethylene mass is an important consideration for stability.
