Lead carbonate is used as a catalyst to polymerize formaldehyde to poly(oxymethylene). It improves the bonding of chloroprene to wire.

Application

Catalyzes the polymerization of formaldehyde to high molecular weight crystalline poly(oxymethylene) products; used in poly(vinyl chloride) friction liners for pulleys on drive cables of hoisting engines; to improve the bond of polychloroprene to metals in wire-reinforced hoses, 10-25 parts of lead carbonate are used ...
