Ban of HA-oils?

The EC parlament
ban some HA-oils in tyres
Sweden and Germany have brought the question of a
ban of some canserogenic HA-oils in tyres to the
EU Commission table in 2003. EU have made an
investigation witch showed that tyres can
contribute with max 2 of the total emisssion of
PAH to the environment

Polycyclic Aromatic Hydrocarbons (PAH)
June 1, 2005 the EC Council took a decision on a
regulation of PAHs in tyres (as a amendment to
76/769/EC) This will come into force on January
1, 2010 The regulation means a demand for a
limit of 10 mg/kg for 8 listed PAHs and a limit
of 1 mg/kg for benz(A)pyrene in extender oils.
These limits are concidered as fulfilled if
extracted PCAs are lt 3 with test method IP346
(not cancerogenic) This concerns only the tread
compound for retreaded tyres

Are all PAHs dangerous?
All HA-oils are not dangerous. The oil is bound
to the rubber by the vulcanization process in a
tyre. Tests with blends of HA oil incorporated
into rubber compounds show no carcinogenic
effects. The PAHs are physically bound in tyre
debrees and they have no carcinogenic
effect. Alternatives are TDAE, MES, Parafin
oils, Naften oils..
