The balance of cost and performance is foremost in consideration for the automotive market. Cost is important due to competition and expected return on investment. Performance can not, however, be compromised due to extended warranties and consumer expectations. The requirements on elastomer components continue to be more demanding, in part due to design. For example, the under-hood temperature continues to increase due to restriction of air flow and the reduction in the size of the engine compartments. Other areas of concern are electrolytic degradation, chemical resistance, permeability, fatigue and crack resistance.
