QUININE BISULFATE Resistant O-Rings and Seals
Quinine Bisulfate is sometimes referred to as Quinbis or Quinate. It is commonly used as an antimalarial and antiarrhythmic drug. When rubber is exposed to Quinine Bisulfate, it can cause embrittlement and cracking of the rubber due to the reaction with the acid. Additionally, it can cause discoloration and fading of the rubber material, as well as swelling and distortion. In some cases, Quinine Bisulfate can also react with the sulfur in the rubber, causing it to degrade further. These effects can worsen over time if the rubber is continually exposed to Quinine Bisulfate.
Fluorosilicone (FVMQ, FSIL)
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.
