Calcium chloride is also known as calcium dichloride, CaCl2, or pickle preservative. It is an inorganic compound used as an electrolyte in batteries, a desiccant, a water-softening agent, and a food preservative. Common industries that use calcium chloride include oil and gas production, deicing, and water treatment.
Exposure of rubber to calcium chloride can lead to several types of failure. The chloride ions in the compound can corrode rubber, leading to cracking, splitting, and flaking. In addition, calcium chloride can absorb moisture from the air and cause the rubber to swell or become brittle. This can reduce the rubber's durability and performance over time. Finally, calcium chloride can cause the rubber to become sticky, leading to the accumulation of dirt and debris which can further degrade the rubber's properties.
