Not-stop rise in raw materials

The cost of the main synthetic rubbers used to manufacture tyres has continued to rise since the start of the year.
According to a survey by Assogomma, during the first half of this year the cost of Styrene Butadiene Rubber (SBR) increased by 80% compared to December 2010. Other synthetic rubbers have increased by an average of 30%. This unprecedented situation is due to the continual monthly increase in the price of the main manomers, including butadiene and acrylonitrile. And as if this were not enough, the now rampant increase in price has been joined by a shortage of material with buying-up and speculation by the Four Asian Tigers.
The price of carbon black, an essential raw material for the manufacture of any article in rubber, also increased by over 40% in the first six months of the year. After a rise of about 10% in January, the price of amorphous silicon remained steady as at June.
There are signs of a deceleration in the price of natural rubber and after the upward trend of previous years, and even at the beginning of this year, it recently returned to last December's levels. However, current prices have more than doubled compared to just a few months ago.
This situation had, and could again have, a direct effect on the price of tyres.
