Potassium sodium tartrate, also known as Rochelle salt, is a naturally occurring potassium salt of tartaric acid. It is commonly used as a food preservative, as a muscle relaxant, as an antacid, and as a stabilizer in many industrial applications. Common types of failure when rubber is exposed to potassium sodium tartrate include cracking, brittleness, and fading of colours. Prolonged exposure to potassium sodium tartrate can cause rubber to become brittle and crack. The rubber may start to fade in colour and the physical properties may become compromised.
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.
