Cadmium chloride, also known as CdCl2, is commonly used as an ingredient in dyes, pigments, inks and paints. It is also used in electroplating, metal finishing and electroforming processes. In the rubber industry, it is used as an accelerator in the vulcanization of rubber compounds to improve their physical properties.
Common types of failures when rubber is exposed to cadmium chloride include accelerated aging, cracking, swelling, hardening, and loss of elasticity. These failures can be caused by the combination of the chloride's oxidizing properties and its ability to irreversibly bind to the rubber material. The cadmium chloride can also cause the rubber material to become brittle and more prone to cracking. In addition, the chloride can cause the rubber to become more susceptible to ozone and ultraviolet light.
