TETRAETHYL LEAD “BLEND” Chemical compatibility with O-rings, rubbers, & plastics

Tetraethyl lead blend is a mixture of tetraethyl lead (TEL) with other chemicals, used primarily as an anti-knock agent in gasoline to improve engine performance and reduce knocking. It was widely used in the 20th century to enhance the octane rating of gasoline, but its use has significantly declined due to environmental and health concerns. Tetraethyl lead blend is also employed in the production of certain specialty chemicals and as an additive in aviation fuels. Proper handling and storage of tetraethyl lead blend are essential to prevent accidents and ensure safety, as it is highly toxic and can pose severe health risks if inhaled or ingested. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with tetraethyl lead blend. Its historical significance as an anti-knock agent and its role in the production of specialty chemicals make tetraethyl lead blend a notable chemical, despite the environmental and health concerns associated with its use.
