As we all know, double-sided foam tape has many performance advantages, such as:
1. Foam double-sided tape has strong heat and corrosion resistance, and can maintain stable adhesion even under temperature changes;
2. Foam double-sided tape has good adhesion to metal, gold-plated surface, plastic, wood, paper, silicone, plastic and other surfaces that are not easy to stick;
3. Acrylic foam has strong flexibility and is easy to seal when used;
4. The double-sided foam tape can absorb external shock, vibration and noise outstandingly;
5. Foam double-sided tape can prevent corrosion between different metals;
6. Foam double-sided tape has ultra-high adhesion and good adhesion durability even in high and low temperature environments;
7. Foam double-sided adhesive has good resistance to chemical solvents, moisture resistance, good initial tack, good mobility, and anti-ultraviolet rays.
However, the quality of products on the market is uneven. How should we distinguish between good quality and bad quality?
When purchasing, you need to judge whether the adhesiveness of the double-sided foam tape is good. You can use the foam tape to stick the item and pull it apart quickly to see the retention. Repeat the pasting several times and then touch it with your hands until the stickiness is obviously reduced and the foam is of good quality. The double-sided tape is more wear-resistant and has longer lasting adhesion.
When purchasing double-sided foam tape, pay attention to determine whether the surface of the tape is smooth and free of wrinkles. Under normal circumstances, you can see bubbles in the double-sided foam tape that has just been produced. After placing it for a week, The bubbles will basically disperse. On the contrary, the sealing glue mixed with impurities has many irregularly distributed white spots, which can not be dissipated by hand. It is also necessary to judge whether the toughness of the tape is good. The better the toughness, the less likely it is for brittle fracture. The high-quality double-sided foam tape has good toughness and can well protect the packaged products.
One of the criteria for distinguishing the quality of double-sided foam tape products is the initial adhesion and the retention force, but the two are inversely proportional. We must understand this point clearly before we can buy the right tape and get better Good use effect.
