Anti-yellowing Aging Test Chamber
Anti-yellowing Aging Test Chamber can provide the simulative heat of the sun and ultraviolet radiation environment of space. It is used for observing the anti-yellowing degree of the sample after a period of time effected by the ultraviolet ray and the temperature. Grey stain can be used for reference standard, to judge it's yellowing degree.

1. This machine can do two tests: Anti-yellowing and aging.
2. Anti-yellowing: To stimulate the environment condition, driven by the sun ultraviolet radiation. It’s generally thought that the appearance change at 50℃ for 9 hours, in theory as exposed to atmosphere for 6 months.
3. Aging: It can promote the increase of sulfur rubber deterioration so as to calculate the change rate of tensile and elongation before and after heat. Its generally thought that test for one day at 70℃, in theory as exposed to the atmosphere for 6 months.
