Glutamic acid is a naturally occurring amino acid and is also known as glutamate, L-glutamate, and glutamate-N. It is commonly used in a variety of industries including food production, pharmaceuticals and as a source of nitrogen for fertilizers.
When rubber is exposed to glutamic acid, it can cause a variety of failures. It can cause the rubber to swell, soften, or crack. In extreme cases the rubber can become brittle and break apart. Over time, the rubber can become discolored, and the surface can become sticky or tacky. In some cases, rubber can become corroded due to the acidity of the glutamic acid, leading to premature failure.
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.
