COPPER FLUORIDE Resistant O-Rings and Seals

Copper Fluoride is also known as cuproufluoride and is commonly used in wastewater treatment, corrosion control, and metal surface treatment. It is also used in the manufacture of glass, ceramics and electronics.

When rubber is exposed to copper fluoride, there are several common types of failure that can occur. These include chemical degradation, cracking, discoloration and embrittlement. Chemical degradation occurs when the copper fluoride molecules break down the rubber material, leading to cracking, discoloration and a decrease in elasticity or strength. Cracking of the rubber material is caused by the copper fluoride molecules absorbing into the rubber, leading to an increase in size and a decrease in physical properties. Discoloration is caused by the copper fluoride molecules forming a thin, insoluble layer on the surface of the rubber, leading to a decrease in flexibility and strength. Embrittlement is caused by the copper fluoride molecules forming an insoluble layer on the surface of the rubber, resulting in a decrease in flexibility and strength.
