How to avoid aging of double-sided tape?

by:CROWN     2021-10-01

Double-sided tape is widely used in our lives, but its service life is time-limited. The aging product cannot guarantee that it can be used during use, so what is the reason for the aging? If it is not used in time, the aging of the transparent belt cannot be ignored, especially the transparent belt used outdoors is often exposed to the sun and is affected by ultraviolet rays for a long time, which will accelerate the degradation of polypropylene.

Therefore, we need to pay attention to these points when using them. When tapes are stored locally, they are mainly waterproof and moisture-proof to prevent moisture during storage, which seriously affects large packaging bags. Service life. Also prevent contact with corrosive substances such as acid, otherwise, it will damage the double-sided tape. It can also prevent high temperature because high temperature will cause the tape to deform, the adhesive will melt, and this situation cannot be used.

Remind us that when we use it, we should also pay attention to the fact that the role of tape not only depends on its own quality problems but also requires cleaning. And boring sticking to the project. Other environmental impacts, so when using it, I forgot to exclude influencing factors outside the boundary.

The base material of the double-sided tape turns the adhesive into a double-sided tape. In other words, the substrate acts as a fixing adhesive. But its important functions don't stop there. The base material of the double-sided tape not only serves to fix the adhesive but also contributes to the function of the double-sided tape.

Substrate and double-sided tape, the task of the substrate is to fix the adhesive and primer. It is relatively thin, flexible and very lubricating. Therefore, it is suitable for almost all purposes in all locations and plans. The substrate itself may be very different-therefore, it can play an important role depending on the location of the double-sided tape, working hours and detailed usage.

Today’s basic material can withstand a certain force and can be separated under a specific force; it can be transparent or reflective; it can have good permeability and can also play a blocking role (such as moisture or oxygen ); It can be very thin (1.5 micronsu003d0.059 mm) or very thick (>3 mm or 118 mm). Modern substrates can be used as gap fillers or silencers. They can also be processed with double-sided tape or die-cut.

The film can be used to make particularly thin tear-resistant double-sided adhesive tapes. However, when different films are used as the base material of the double-sided tape, the difference is also great. The detailed information depends on the material of the substrate: polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), or other materials.
