Sodium Pyrophosphate, also known as tetrasodium pyrophosphate, is a chemical used in cleaning products and as an emulsifier in food. It is also used in the production of detergents, soaps, and other products.
When rubber is exposed to sodium pyrophosphate, it can become swollen and brittle. The rubber may become vulnerable to cracking, tearing, and other forms of mechanical damage, leading to a decrease in strength and elasticity. Additionally, the rubber may become more prone to discoloration due to chemical interactions. In extreme cases, the rubber may become warped or distorted due to prolonged exposure to the chemical.
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.
