u003cbru003eu003cpu003e Endurance board (also known as PC sheets
, polycarbonate board, bulletproof glass, cabron board, plastic solid board) is processed by high-performance engineering plastic polycarbonate. The endurance board is impact resistant, unbreakable, tough and safe, anti-theft, and has the best bulletproof effect. For novice consumers, how to distinguish the quality of PC endurance board is very troublesome. Generally speaking, endurance board and polycarbonate sheet
are divided into 3 grades according to their quality. In order to adapt to different customer groups and customer needs, the products are divided into three grades according to the quality assurance, a 10-year warranty, a 5-year warranty, and a 3-year warranty. The brand, raw material, quality, and price of each grade are different. In addition, some PC endurance board manufacturers provide low-end PC endurance boards. Under the situation that the price of endurance board is greatly shaken in the market, customers only have to understand these, and then they can choose according to their products' uses and needs. As the saying goes, you get what you pay for. In the face of products with too low prices, customers should pay more attention to whether the products meet the required quality standards. At the same time, it should be noted that some merchants use shoddy products, otherwise they have spent 10 years of warranty money to buy products that are 5 years or 3 years or even worse. The following editor of endurance board manufacturers will introduce a few simple methods to judge the quality level of endurance boards. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e1. Look at the transparency of the PC endurance board. The polycarbonate (sheets) produced by imported raw materials are very clear and transparent. For example, 3MM thick transparent endurance boards are transparent. The light rate is 92%. The light transmittance of the 8mm thick transparent endurance board is 83.3%, which is similar to glass.u003c/pu003eu003cpu003e2. Tear off the protective film on the surface of the and check the board surface Whether it is flat, whether there are bubbles, particles. If the particles and bubbles are large, it means that the raw materials for producing this batch of PC endurance boards are poor and belong to low-grade boards.u003c/pu003eu003cpu003e3. Measure the actual PC endurance boards Thickness. When the regular endurance board manufacturers produce, they will control the thickness of the board within the tolerance range of the national standard, that is, when the customer orders a 3mm pc endurance board, the thickness of the board is 3mm thick. On the contrary, it is produced by a factory of poor quality or cutting corners.u003c/pu003eu003cpu003e4. If possible, you can also use a small endurance board for testing and ignite it with a lighter. The quality is better. The endurance board produced will extinguish itself when it leaves the fire source. The high molecular weight of the PC raw material makes this kind of board difficult to break and break.u003c/pu003eu003c/pu003eu003c/pu003eu003c/pu003eu003c/pu003eu003c /pu003eu003c/pu003eu003c/pu003ecustom polycarbonate sheet
