Some acrylic sheet after a period of time will appear yellowing, cracking, and even whitening. This is why?
1. The temperature is too high, which will cause aging and yellowing under high temperature for a long time;
2. The aging is caused by the long exposure time;
3. It reacts with organic solvents and produces chemical reaction aging.
These three situations are the main reasons for the yellowing of acrylic panels.
The use of products when the external environment can not be changed, so in order to extend the service life of acrylic, you need to choose the better quality.
However, at the time of purchase, because the acrylic sheet is transparent, customers believe that the products do not vary much and are not carefully selected. In fact, every item has a grade and quality differences, the more transparent these differences can not be seen. If the choice of acrylic sheet is not brand new material or good raw materials produced by the plate, the performance of the plate in all aspects is not stable.
Secondly, these plates are ineffective in fighting ultraviolet and fighting outdoor aging. The power of ultraviolet light is very strong, and if the plates are not designed and built to solve these problems, there will be yellowing and whitening, and the end result will be the loss of acrylic strength and eventual bursting.
So how to choose a good acrylic plate, is there any way to detect?
Here Eyeshine summarizes three methods for you, I hope it can help you
