Zinc nitrate is a white crystalline compound that is also known as zinc dinitrate, zinc bisulfate and zinc nitrohydrochloride. It is commonly used as a fertilizer, an oxidizing agent in industrial processes and a preservative in the food and pharmaceutical industries.
When rubber is exposed to zinc nitrate, it can cause the rubber to harden, swell, and eventually crack due to dry rot. It can also cause the rubber to become brittle, discolored and stained. Over time, the rubber may become more porous and fragile, leading to further degradation. Additionally, the rubber may become more susceptible to cracking and splitting.
