How is the Yellowing Index of Polycarbonate Determined?
Now you will understand its polycarbonate yellowing index and be familiar with its determination process. Yellow index (YI) is a spectral information, is all-natural or synthetic light resources, light and shade (white) yellow can be used as a distinguishing indicator. In industries, it is determined in regards to "delta YI" which is represented as ΔYI. For example, when a Polycarbonate Sheet is exposed to ultraviolet radiation, it turns yellow after a certain amount of time. This way of color modification is known as polycarbonate yellowing index. More readily or willingly, index accessibility involves the collection of comparative measures and assessments over a given period of time. It is important to monitor the processing of samples because some surfaces can be easily modified This inevitably leads to mistaken final thinking. As one of the basic concepts of many industrial idioms yellow index plays an important role. This is because they can be used to p
