Butyric anhydride, also known as butanoic anhydride, is an organic compound that is used in the production of polymers, pigments, and esters. It is also used as a solvent and an intermediate in the manufacture of various drugs.
When rubber is exposed to butyric anhydride, it can cause the rubber to become brittle and cracked due to the oxidation process. It can also cause the rubber to swell and weaken, resulting in cracking and tearing. In addition, exposure to UV light can cause the rubber to discolor, fade, and crack. High temperatures and concentrations of butyric anhydride can also cause the rubber to become sticky.
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.
