CARBON BLACK AND POLYCYCLIC AROMATIC HYDROCARBONS - TECHNICAL ISSUES AND REGULATIONS

摘要

Changing expectations and performance requirements are making ever increasing demands of elastomeric compounds. Traditionally these requirements have included surface appearance, conductivity and dynamic performance. However due to increasing awareness of the possible health effects of chemical exposure, rubber manufacturers now have to comply with increasing numbers of chemical regulations such as REACH. A new area of increasing concern is polycyclic aromatic hydrocarbon (PAH) content in rubber articles. This increasing interest has led to a number of new regulations and market initiatives that can be difficult to meet without careful selection of raw materials. In this paper the relationship between carbon black and PAH content is discussed.
