POTASSIUM PHOSPHATE, DIBASIC OR TRIBASIC Resistant O-Rings and Seals
Potassium phosphate, also known as dibasic or tribasic, is a salt of phosphoric acid commonly used in industry and agriculture. It is a key ingredient in fertilizer, buffers, food preservatives, dental products, and detergents. Potassium phosphate is also extensively used in the medical industry as an intravenous fluid.
When rubber is exposed to potassium phosphate, it can cause degradation, cracking, and hardening of the rubber due to the presence of the salt. Additionally, the presence of the salt can cause the rubber to weaken and become brittle in certain circumstances. The salt can also cause the rubber to swell and become more porous, leading to further degradation.
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.
