Potassium permanganate is also known as Condy's crystals, permanganate of potash, and chameleon mineral. It is a widely used oxidizing agent in the chemical industry and is commonly used in water purification, wine-making, tanning, and textile dyeing.
When rubber is exposed to potassium permanganate, the rubber can become brittle and prone to cracking. The chemical can also cause oxidation of the rubber, leading to discoloration and a decrease in physical strength. In extreme cases, exposure to potassium permanganate can cause the rubber to break into pieces.
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.
