So what should we do when choosing fluorescent whitening agents for high-temperature plastic products Selection, rqt-b-5 high temperature rigid plastic products fluorescent whitening agent. The production temperature of plastic products is more than one hundred degrees, two hundred degrees and three hundred degrees. We often encounter plastic products of more than one hundred degrees and two hundred degrees. Of course, many whitening agents are also very suitable. However, the production temperature of plastic products of more than three hundred degrees is relatively high, and many whitening agents cannot be used. The melting point has reached the point after use, not only the whitening effect can not be achieved. Therefore, it is better to choose special whitening agent for high temperature plastics. Rqt-b-5 fluorescent whitening agent for high temperature rigid plastic products.
