Description
Lead(II) oxide, commercially known as Litharge and listed under C.I. 77577 (CAS 1317-36-8, EC 215-267-0), is an inorganic lead compound supplied as a light yellow-orange powder. It carries no E-code designation and is classified under HS code 28241000.
In rubber and tire manufacturing, Lead(II) oxide acts as a vulcanization accelerator, forming cross-links within polymer chains to improve mechanical durability. In mining and metals processing, it serves as a catalyst in ore smelting and refining operations, facilitating oxidation reactions that separate base metals from slag.
This product is subject to REACH regulation and requires an up-to-date Safety Data Sheet due to its classification as a hazardous substance. Procurement teams should confirm supplier registration status and downstream use authorization before ordering. Standard packaging formats vary by supplier; buyers are advised to request grade specifications and compliance documentation at the time of inquiry.
