vulcanization


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

vulcanization,

n the process of treating crude rubber to improve such qualities as strength and hardness. This process usually involves heating the rubber with sulfur in the presence of moisture, the sulfur uniting with the rubber to produce saturated double bonds.
