Ozone effect on rubber
WebA large part of gasoline and diesel engine pollution consists of two components: soot and nitrogen oxides, or NOx. Soot is made up of tiny carbon particles that hang in the air and dirty it, but NOx, a mix of nitric oxide and nitrogen dioxide, has a more complicated story. NOx feeds chemical pathways that are fueled by sunlight and produce the noxious brew we … WebMay 7, 2024 · Ozone testing is conducted to predict how a material will react to prolonged or repeated exposure to ozone gas. For example, ozone degradation occurs when traces of ozone in the air attack double bonds in rubber chains. This effect is most common in natural rubber, polybutadiene, styrene-butadiene rubber and nitrile rubber due to their double ...
