1) The English full name of PS is Polystyrene, and the Chinese translation is polystyrene. The conventional colors are black and white, and other colors can also be customized according to customer requirements, but the minimum order quantity of the color sheet is very high, and the color sheet of the anti-static tray can only be made into an anti-static index to the power of 9-11 , if the demand is small and the anti-static value is high, it is generally not recommended to use.
The PS black sheet can be made into anti-static blister trays with three index levels, while the white anti-static index can only reach the power of 9-11.
The first type: anti-static blister tray (anti-static index 9-11 power) Under normal circumstances, the use time is about 3-6 months. However, the anti-static value is easily affected by the environment, air, temperature and humidity, which will shorten the anti-static service life. The unit price is lower than that of semi-conductive and conductive materials. It is recommended for customers who do not require high anti-static index and have a short service life.
The second type: semi-conductive blister tray (anti-static index 6-9 power) under normal circumstances, the use time is about half a year to one year. The anti-static value is not affected by the environment, air, temperature and humidity, but because its price is comparable to that of conductive materials, and the anti-static index of conductive materials is more stable, it is established to choose the latter.
The third type: conductive blister tray, which can also be called permanent anti-static tray (anti-static index 3-6 power). Under normal circumstances, the use time is about half a year to 1-3 years, and the anti-static value is not affected by the environment. Effects of air, temperature and humidity. At present, 80% of blister manufacturers in the industry cannot achieve this effect. Yingshuo Packaging has obvious advantages in conductive blister trays. It is a long-term supplier of conductive blister trays in the world's top 500 companies such as Sumitomo, Huawei, and Amphenol.
2) The full English name of PP is Polypropylene, and the Chinese translation is polypropylene. There are two kinds of conventional colors, black and natural color. The natural color is transparent, foggy and slightly white, and can also be called translucent. PP and PS have a lot in common. Like PS, color sheets and natural colors can only be made into anti-static 9-11 power static index, and the minimum order quantity of color sheets is very high, so it is generally not recommended to use. PP is the most resistant to high temperature among all materials, and its heat distortion temperature is 80-120°C. Compared with the other three materials, PP material is soft. PP black anti-static sheet is the same as PS, and can be made into anti-static trays with three index levels. For specific reference data, see the detailed introduction of PS above.
