After directly exposed to the sun in the shipping container, some materials, like rubber & shoes, may fade, discolor, and age. So Aging Chamber, Accelerated Angle Chamber, Aging Testing Machine, Aging Tester, Aging Test Chamber can simulate the circumstances of sunshine radiation in containers to test the resistance to discoloration of materials. The aging chamber can do kinds of testing Aging and anti yellowing. Aging the chamber can promote the increase of sulfur rubber deterioration, to calculation the change rate of tensile and elongation before and after heat. It’s generally thought that test for one day at 70 degree in theory as exposed to the atmosphere for 6 months. Anti - Yellowing the chamber stimulate the atmosphere environment, driven by the sun ultraviolet radiation. Its generally thought that the appearance change at 50 degree for 9 hours in theory as exposed to atmosphere for 6 months.
