MONOMETHYL HYDRAZINE Chemical compatibility with O-rings, rubbers, & plastics

Monomethyl hydrazine (MMH) is a highly reactive and toxic chemical used primarily as a rocket propellant. It is a key component in hypergolic propellants, which ignite spontaneously upon contact with an oxidizer. MMH is also used as an intermediate in the synthesis of pharmaceuticals and other chemicals. Due to its high toxicity and reactivity, proper handling and storage of monomethyl hydrazine are essential to prevent exposure and accidents. Safety measures should include the use of personal protective equipment, proper ventilation, and adherence to manufacturer guidelines. Specialized training and protocols are necessary for handling MMH, ensuring the safety of personnel and the environment. Regular monitoring and maintenance of systems using monomethyl hydrazine ensure optimal performance and safety, making it a critical component in aerospace and chemical industries.
