How to choose ESD warning tape
ESD warning tape is made of PVC film as the base material and coated with rubber pressure sensitive adhesive. ESD warning tape has the advantages of waterproof, moisture-proof, weather-resistant, corrosion-resistant, anti-static, etc., and is suitable for the corrosion protection of underground pipelines such as air pipes, water pipes, and oil pipelines. When choosing ESD warning tape, there are the following aspects to pay attention to:
1. Smell the smell, if the smell is very strong, there is a sour smell, the retention of this kind of warning tape is very poor, especially in the low temperature environment, it will crack when it basically sticks to the carton, and the stronger the smell, the initial adhesion will be felt It is still very sticky, but the adhesive surface will soon become dry and lose its adhesiveness. At that time, cracks appear on the surface of the tape because of uneven glue application.
2. Looking at the brightness of the film, generally inferior warning tapes are dark in color. This kind of warning tape has a very high probability of breaking and has poor strength.
3. Look at the color. Generally, the whiter the appearance of the warning tape and the less impurities in the warning tape can ensure normal adhesiveness. The warning tape below 100 meters has a certain degree of transparency and the paper tube can be seen. For yellow tape, see if there are irregular white spots on the surface of the tape. What can't be wiped off by hand is the mark of impurities or glue. This kind of product generally has an odor.
4. The thickness of the hand-feel film and the warning tape that feels hard are generally inferior, and due to the thickness of the film, the actual number of meters will be reduced. The films selected for good warning tapes are relatively soft and have good stretchability by hand.
ESD warning tape can be used for floor area warnings, packaging box sealing warnings, product packaging warnings, etc. The color is black on yellow background, Chinese and English warning slogans, and the viscosity is oily extra-high viscosity rubber glue. The surface resistance of the anti-static warning tape is 106- 109 ohm, warning tape is used to identify warning areas, segment risk warnings, label classification, etc. There are black, yellow, red, and white lines to choose from; the surface is resistant to wear, can accept high-flow pedals, and has good adhesion. Certain anti-corrosion, acid-base properties, anti-wear.
