POTASSIUM ACID SULFATE Resistant O-Rings and Seals
Potassium acid sulfate, also known as potassium hydrogen sulfate, is a colorless, odorless crystalline solid. It is commonly used as a fertilizer, a laboratory reagent, and for leather tanning. It is also used to produce a variety of other chemicals.
When rubber is exposed to potassium acid sulfate, it can cause a number of different types of failures. The most common is oxidative deterioration of the material, which can lead to the rubber becoming brittle and cracked. In addition, the acidity of the potassium acid sulfate can also cause corrosion of the rubber, leading to further deterioration of the material. Furthermore, the presence of sulfate ions can cause swelling of the rubber, which can reduce the material's strength and lead to premature failure.
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.
