POTASSIUM DIPHOSPHATE Resistant O-Rings and Seals
Potassium Diphosphate is also known as dipotassium hydrogen phosphate and potassium phosphate. It is commonly used as a buffering agent, nutrient, and food additive in the food, pharmaceutical, and industrial industries. When exposed to rubber, Potassium Diphosphate can cause swelling, cracking, and brittleness in the rubber. This is due to the high acidity of the chemical, which can cause rubber to degrade over time. In addition, the chemical can corrode metal components that may be attached to the rubber, leading to further deterioration.
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.
