Lead nitrate is also known as lead(II) nitrate, nitrate of lead, and lead dinitrate. It is commonly used in glass manufacturing, as a flux in galvanizing, as a drier in paint and varnish and as an ingredient in explosives.
When rubber is exposed to lead nitrate, it can cause a variety of failures, including oxidation, swelling, brittleness and cracking. Oxidation is the most common problem, as the lead nitrate will react with the rubber, leading to a breakdown of the rubber's molecular structure. Swelling and brittleness can also occur due to an increase in the amount of water absorbed by the rubber. Cracking can occur when the rubber is exposed to temperatures above the rubber's melting point.
