SODIUM THIOCYANATE Resistant O-Rings and Seals
Sodium Thiocyanate, also known as Sodium R-Cyano-R-Thioacetate, Sulfo-Cyanic Acid, and Sulfocyanic Acid, is a chemical compound commonly used in the pharmaceutical industry, in the production of dyes and pigments, and in the manufacture of paper and textiles. Common failures when rubber is exposed to Sodium Thiocyanate can include swelling, cracking, and discoloration. Sodium Thiocyanate can also cause rubber to become more brittle, leading to failure over time due to brittleness.
