Ozone Aging Test
Brief Introduction: The test subjects of ozone aging tests are mainly rubber products. Ozone adds to the double bonds in rubber, forming primary ozonides, which then decompose to produce substances like ketones and aldehydes. Ozone aging typically starts on the surface of rubber products, often forming a film first, which then cracks. Under external forces, the film is prone to continuous fracturing and peeling, creating a fresh surface. This fresh surface reacts with ozone, leading to further aging. As a result, rubber products in motion continuously thin out from thick to thin, with aging progressing longitudinally until the rubber is completely destroyed.
Application Fields: Rubber, rubber products, plastics, tires, seals, etc.
Primary Equipment: Royal Oxygen Aging Test Chamber.
Reference Standards: GB/T7762, ISO 14131-1, GB/T13642, ISO 1431-2, etc.
