POTASSIUM PYROSULFATE Resistant O-Rings and Seals
Potassium pyrosulfate, also known as potassium disulfate, is a salt compound used primarily in agriculture as a fertilizer and soil conditioner. It is also used in the manufacturing of glass and ceramics, as a food additive, and as an oxidizing agent in fuel cells.
When exposed to potassium pyrosulfate, rubber can suffer from a number of different types of damage. This includes cracking, hardening, and discoloration of the material. The salt can also cause the rubber to swell and become more porous, leading to further degradation. Additionally, the salt can corrode the rubber, leading to a breakdown of the material and a decrease in strength and flexibility.
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.
