TRIMETHYLAMINE Resistant O-Rings and Seals
Trimethylamine, also known as TMA or N-methylmethanamine, is a colorless, flammable gas with a fishy odor. It is commonly used in the production of pharmaceuticals, agricultural chemicals, flavO-Rings and fragrances, and is also used as a precursor for the production of plasticizers, surfactants, and other specialty chemicals.
When rubber is exposed to trimethylamine, the most common type of failure is accelerated ozone cracking. Ozone cracking is the process of ozone molecules permeating rubber, causing cracks and weakening the rubber. The presence of trimethylamine speeds up this process as it increases the concentration of ozone in the atmosphere. Additionally, ozone cracking can be accelerated by heat and prolonged exposure to sunlight.
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.
