DIMETHYL HYDRAZINE Resistant O-Rings and Seals
Dimethylhydrazine is also known as unsymmetrical dimethylhydrazine (UDMH) and is primarily used as a rocket fuel and as an agricultural fertilizer. It is often used as an intermediate reactant in synthesizing other compounds. It can also be used as a solvent in some industrial applications.
When rubber is exposed to dimethylhydrazine, the chemical can cause swelling, softening and embrittlement of the rubber. This can lead to cracking, tearing, and other physical deformation of the rubber. Additionally, dimethylhydrazine can corrode metal parts which can be in contact with the rubber, leading to further weakening and failure of the rubber seal.
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.
