Sodium iodide is also known as sodium salt and is used as a nutritional supplement and in some medical treatments. Common uses for sodium iodide include treating thyroid disorders, such as hypothyroidism, and as a radioactive tracer used in medical imaging.
When rubber is exposed to sodium iodide, common types of failure include swelling, softening, discoloration, and cracking. The chemical can break down the chemical bonds of rubber, leading to physical degradation. Additionally, the chemical can cause surface erosion and chemical attack on the rubber, resulting in the breakdown of the material. It can also cause a change in the rubber's structure and properties, leading to reduced strength and performance.
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.
