Yellowing resistance test chamber is suitable for simulating ultraviolet radiation and heat of sunlight,
The sample was irradiated by ultraviolet light and acted with temperature in the machine, and observed after a period of time
The degree of yellowing resistance of the sample can be used as a reference to determine the grade of yellowing.
The testing time depends on the manufacturer's agreement. Machine accessories are complete, can be used as a basic yellow resistance. Variable test, can also be used as aging testing machine and oven, has a multi-purpose function.
