Zinc oxide is a white powdery compound also known as zincic oxide, zinc white, and calamine. It is commonly used as an additive in plastics, rubber and ceramics, as a pigment in paint and cosmetics, and as a protective coating for wood and other materials.
When rubber is exposed to zinc oxide, it can cause the rubber to become brittle and discolored. It may also cause the rubber to swell and shrink due to oxidation, which can lead to cracking and splitting in the material. Additionally, zinc oxide can cause the rubber to become more porous, making it less able to resist damage from oils, solvents, and other chemicals.
