SODIUM NITRATE Resistant O-Rings and Seals
Sodium Nitrate is also known as Chile Saltpeter and Saltpeter. Common uses for Sodium Nitrate include fertilizer, explosives, and food preservatives.
When rubber is exposed to Sodium Nitrate, it can cause the rubber to become brittle and harden. This can lead to cracking and eventual failure of the rubber product. Sodium Nitrate can also cause accelerated oxidation of the rubber material, leading to premature aging and degradation. In some cases, Sodium Nitrate can also cause the rubber to swell and deform, leading to further weakening of the material.
