Ethanol, also known as ethyl alcohol or grain alcohol, is a clear, colorless, volatile liquid with a slight odor and a bitter taste. It is used as an antiseptic and as a solvent in many industries, including the food, beverage, and pharmaceutical industries. It is also used as a fuel for cars and as a fuel additive.
When rubber is exposed to ethanol, it can become brittle and cause cracking. Additionally, the rubber may swell, leading to further deterioration of the seal. The rubber may also become discolored due to chemical reactions with the ethanol. Ethanol can also cause permeation, resulting in gas leakage and a reduction in the mechanical strength of the rubber seal.
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.
