Product Description: The product is suitable for simulating ultraviolet radiation and heat of sunlight. The sample is exposed to ultraviolet radiation and temperature in the machine. After a period of time, observe the degree of resistance of the sample to yellowing. You can use the stained gray mark as a reference to determine its yellowing The level and test time are determined by the manufacturer's agreement. The machine has a complete set of accessories, which can be used as a basic yellowing resistance test, and can also be used as an aging tester and oven, presenting a machine with multi-purpose functions. Aging: This machine is promoting the deterioration of vulcanized rubber to calculate the rate of change of tensile force and elongation before and after heating. It is generally considered that testing at 70°C for one day is theoretically equivalent to 6 months of exposure to the atmosphere. Yellow resistance: This machine simulates the atmospheric environment and is exposed to ultraviolet rays from the sun. The appearance change is generally considered to be tested at 50 ℃ for 9 hours, which is theoretically equivalent to 6 months of exposure to the atmosphere. Standards Compliant: Comply with: HG/T3689 GB/T18830, ASTM D1148, ISO8580 standards.
