The anti-static plastic tray can protect the product from damage. Then the question arises: how long can the anti-static tray be used, and what impact will it be affected by to shorten its cycle and reduce the anti-static service life? Anti static tray (anti-static tray) is divided into conductive plastic tray, semi conductive plastic tray and anti-static plastic tray.
Their indexes are respectively: conductive plastic tray: (3-5 power of anti-static index) semi conductive plastic tray: (6-8 power of anti-static index) anti-static plastic tray: (9-11 power of anti-static index) anti-static plastic tray is generally required to be selected only when the anti-static time is not long. The above two grades require high anti-static requirements. The commonly used sheets of anti-static tray are: PS/PP, and the conventional color is black. The white anti-static can only reach the power of 9-11. Then we will ask whether the higher their index is, the longer their anti-static time will be. The answer is wrong. On the contrary, the smaller their index is, the longer their anti-static time will be. The larger their index is, the shorter their anti-static time will be.
One type: conductive plastic tray, which also becomes a permanent anti-static plastic tray. It can be used for 1-3 years under normal conditions. The anti-static value is not affected by the environment, air, temperature and humidity. The reason why it is called durable anti-static is that the service life of general trays is so long, so it is called durable. The second type: semi conductive plastic tray, which is normally used for about half a year to one year. The anti-static index is not affected by the environment, air and humidity, but its price is equivalent to that of conductive materials, and the anti-static index of conductive materials is more stable, so the latter is recommended.
The third type: anti-static plastic tray. Normally, it will be used for 3-6 months. Note that its anti-static value will be affected by the environment, air, temperature and humidity, which will shorten the service life of anti-static. The unit price is lower than that of conductive and semi conductive materials. It is recommended to use it for customers whose anti-static service life is not long.
