高芳烃油(HA油)最初广泛用于轮胎胶料,因为它们与天然橡胶以及合成橡胶具有良好的相容性。高芳烃油也称为蒸馏芳烃萃取物(DAE),其含有较高浓度的多环芳烃(PAH)。PAH是有机化合物,有两个或多个芳香环,其中有8类被列为致癌物。按照欧洲法规,从2010年1月起,如果填充油含有超过1mg/kg(质量分数为0.0001%)的苯并(a)芘以及所列PAH的总量超过10mg/kg(质量分数0.001%),则不能投放市场或用于生产轮胎。如果在二甲基亚砜DMSO萃取(IP346试验方法)试验中的多环芳烃萃取物
High aromatic oil (HA oil) was originally widely used in tire rubber because of its good compatibility with natural rubber and synthetic rubber. High aromatic oils, also known as distillate aromatic extracts (DAEs), contain higher concentrations of polycyclic aromatic hydrocarbons (PAHs). PAH is an organic compound with two or more aromatic rings, of which eight are classified as carcinogens. According to the European regulations, starting from January 2010, if the filling oil contains more than 1 mg / kg of benzo (a) pyrene and the total amount of PAH listed exceeds 10 mg / kg (0.001% by mass) , It can not be put on the market or used to produce tires. If the polycyclic aromatic extract in DMSO DMSO extraction (IP346 test method) test
