Calcium nitrate, also known as Niter, is a common chemical used in many industries for a variety of applications. It is used in fertilizers to provide nitrogen to plants, as a preservative for food products, and as a component in concrete and construction materials.
When rubber is exposed to calcium nitrate, the rubber can become brittle and crack due to the corrosive effects of the chemical. In addition, the rubber may become discolored and lose its flexibility. It is important to use rubber materials that are specifically formulated to resist calcium nitrate, as these materials will be more suited to resist the chemical's corrosive properties and maintain their intended properties.
