POTASSIUM COPPER CYANIDE Resistant O-Rings and Seals
Potassium copper cyanide, also known as Potassium Dicyanoaurate (II), is a widely used chemical in industrial processes and has a variety of applications. Commonly used in electroplating, gold-plating, and as a raw material in the production of alloys and chemical compounds, this chemical is also used in the food industry.
When exposed to rubber, potassium copper cyanide can cause a variety of types of failures. The most common type of failure is a chemical degradation of the rubber, which can lead to cracking, tearing, or discoloration. Additionally, this chemical can cause swelling or hardening of the rubber, which can lead to a decrease in flexibility and strength.
