PHTHALIC ANHYDRIDE Resistant O-Rings and Seals
Phthalic anhydride is also known as benzene-1,2-dicarboxylic anhydride and is mainly used in the production of plastics and coatings. It is also used in the production of dyes and as an intermediate in the production of some solvents.
When rubber is exposed to phthalic anhydride, it can become brittle, swell, discolour, and crack. The anhydride is known to be corrosive and can weaken the structural integrity of the rubber over time. Additionally, it can cause staining and make the rubber more prone to tearing and cracking.
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.
