Product Description

The yellowing resistance test box is used to simulate the ultraviolet radiation and heat of the sun. The sample is exposed to ultraviolet radiation and temperature in the machine

The function of the yellowing resistance test box is to simulate the ultraviolet radiation and heat of the sun. The sample is exposed to ultraviolet radiation and temperature in the machine. After a period of time, observe the degree of yellowing resistance of the sample (it is generally believed that the material tested in the box for 3 hours at 70 ℃ is equivalent to the yellowing effect in the natural environment for 2 months). The stained gray mark can be used as a reference to determine the yellowing grade, The yellowing resistance test box can also be used as a heat aging test machine and oven, showing the function of one machine for multiple purposes
