Glauber's salt, also known as sodium sulfate decahydrate or sulfate of soda, is a white crystalline salt commonly used in a variety of industries. It has multiple uses such as a preservative, a component of cement and concrete, a component of detergent, a water softener, a food preservative, and a dyeing agent.
When rubber is exposed to Glauber's salt, it can be subject to many different types of failure. The most common type of failure is accelerated oxidation and degradation of the rubber, leading to a decrease in flexibility and strength. Additionally, Glauber's salt can cause rubber to swell, leading to a loss of dimensional stability, as well as a decrease in elasticity and tear strength. In some cases, exposure to Glauber's salt can also lead to increased porosity, making the rubber more prone to cracking and splitting.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
