POTASSIUM PHOSPHATE, ACIDIC Resistant O-Rings and Seals
Potassium phosphate, also known as dipotassium phosphate, is an acidic salt commonly used as a buffering agent, fertilizer, and food additive. It is frequently used in the production of detergents, cleaning products, and pharmaceuticals.
When rubber is exposed to potassium phosphate, it can be corroded and degraded due to the acidic nature of the chemical. Additionally, the rubber can become brittle and crack more easily as a result of the acid attack. In extreme cases, the rubber may become so damaged that it breaks apart completely.
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.
