INFLUENCE OF MINERAL-OIL PLASTICIZER-CHAR ACTERIZATION, FILLER AND POLYMER ON PAH CONCENTRATION IN VULCANIZATION FUMES

In the fume resulting from the vulcanization of rubber products are tr ace quantities of carcinogenic aromatic polycyclic hydrocarbons (PAH). The results of the experiments presented here show that a reduction o f the PAH content of vulcanization fume is achieved through the use of mineral oil with low PAH levels. The compound ingredients also influe nce PAH emission. Both the fillers of reinforcing agents and the polym er matrix dependent upon their aromaticity, can reduce PAH emission. T his illustrates that methods with the legally required minimisation of carcinogens in the work place can be achieved.
