Zinc Stearate is also commonly known as Octadecanoic Acid and Zinc Salt. It is a white powder commonly used in the rubber industry as a release agent, lubricant, and anti-blocking agent. It is also used in the plastic, ceramic and cosmetics industries as a mold release agent and additive.
Common failures when rubber is exposed to Zinc Stearate are hardening, cracking and brittleness of the rubber due to the zinc stearate reacting with the rubber material. The rubber can also become tacky and sticky due to the zinc stearate. Additionally, the rubber can become discolored and have poor physical properties due to the zinc stearate reacting with the rubber material.
