GB/T2951.21-2008 Lab Drying Oven Ozone Aging Test Chamber Environmental Chamber

Product use:

This ozone aging test equipment can be used for rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheaths and other products, under static tension or continuous dynamic tension deformation, or intermittent dynamic tension and static tension alternate deformation After exposing to a closed, non-illuminated air containing constant ozone concentration and a constant temperature test box, the sample is tested for a predetermined time, and the degree of cracking or other performance changes on the surface of the sample is evaluated to assess the resistance of the rubber Ozone aging performance. With advanced processing equipment, superb manufacturing technology, strict management system, strong technical strength and good after-sales service, it is the preferred supplier of major scientific research institutes, famous enterprises and universities.
