Greetings again!
Do you know that the Extender oils, commonly used in the rubber industry , can contain different levels of polycyclic aromatic hydrocarbons (PAHs). PAH’s are organic substances which hazardous properties are toxic for humans and the environment.
Tyre Industry uses huge quanties of these materials!
Friends, these materials are going to get banned from 2009 December !! Now you need to study about a new class of oil along with conventional extender oils for Rubber. (ie. Aromatic,Naphthenic, Paraffinic oils ).
I know you have so many quieries on it. Do visit this official document on this hot issue on PAH !! (www.etrma.org/pdf/Q&A-version_EN_Dec_05.pdf )
