Method for screening quality and grade of PC endurance board
 
      Endurance board (also known as PC board, polycarbonate board, bulletproof glass, cabron plate, plastic solid board) is made of high-performance engineering plastic polycarbonate. The endurance board is impact resistant, unbreakable, tough and safe, and has the best anti-theft and bulletproof effect. For first-time consumers, the question of how to distinguish the quality of PC endurance boards is very troublesome. Generally speaking, there are 3 grades of endurance board and sunshine board according to quality. In order to adapt to different customer groups and customer needs, the product is divided into three grades according to the quality assurance, 10-year warranty, 5-year warranty, and 3-year warranty. The brand, raw materials, quality, and price of each grade are different. In addition, some PC endurance board manufacturers provide low-end PC endurance boards. When the endurance board price market fluctuates greatly, customers only need to understand these, and they can choose according to their product uses and needs. As the saying goes, it ’s a penny and a penny. In the face of products that are too low in price, should customers pay more attention when buying, whether the products meet the required quality specifications. At the same time, we should also pay attention to some businesses that are sub-charged, otherwise they spent 10 years of warranty money to buy products for 5 years or 3 years or even worse. The editor of the endurance board manufacturer, Hua Hong, will introduce a few simple methods to judge the quality level of the endurance board.

Endurance board

     1. Look at the transparency of the PC endurance board. The polycarbonate produced by imported raw materials (plates are very clear and transparent. For example, the 3MM thick transparent endurance board has a light transmittance of 92%. The 8mm thick transparent endurance board is transparent The light rate is 83.3%, which is similar to glass.

     2. Tear off the protective film on the surface of the pc board to see if the board surface is smooth, whether there are bubbles or particles. If the particles and bubbles are larger, it means that the raw materials for producing this batch of PC endurance boards are poor and belong to low-end boards.

     3. Measure the actual thickness of PC endurance board. When regular endurance board manufacturers produce, they will control the thickness of the board within the tolerance of the national standard, that is, the customer orders 3mm pc endurance board. The thickness is 3mm thick. On the contrary, it is produced in factories of poor quality or cut corners.

     4. If possible, you can also use a small endurance board for testing, and use a lighter to ignite it. The endurance board made of better quality PC materials will extinguish itself when it leaves the fire source. The PC material has a high molecular weight, so this kind of board is not easy to break and break.
