SODIUM NITRITE Resistant O-Rings and Seals
Sodium Nitrite is also known as Chile Nitrate and Nitrite of Soda. It is commonly used as a food preservative, in the production of dye, and as a curing agent for meats.
When rubber is exposed to Sodium Nitrite, it can cause accelerated oxidation of the rubber material, leading to premature aging and degradation. It can also cause the rubber to swell and deform, leading to further weakening of the material. Additionally, Sodium Nitrite can cause the rubber to become brittle and harden, leading to cracking and eventual failure of the rubber product.
