When rubber is exposed to quinine hydrochloride, the rubber can become brittle and cracked, leading to swelling, cracking, and ultimately, failure. The rubber can also become discolored due to the chemical reaction. Additionally, the rubber can become less flexible and more prone to breaking. In extreme cases, the rubber can become completely degraded, resulting in complete 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.
