Reflective tape products are basically used outdoors, so the selected substrates are basically UV-resistant and high-temperature resistant. But in fact, the waterproof effect is also very important in the outdoor environment. Today we will take a look at the waterproof problem of various materials of reflective tape.
Take the reflective tape of Kunshan Yuhuan Package Material Co., Ltd. as an example. There are various materials such as PVC, PU, PMMA, etc. Which material is more waterproof? PVC material is very soft, durable and non-flammable, and it can be printed. However, this material has poor photo-thermal stability, photo-oxidation and decomposition, resulting in yellowing and brittleness, but it has low water vapor leakage and is relatively waterproof. The PU material is elastic, resistant to low temperature and aging, and the hard PU material has low water absorption, but the soft PU material used in the reflective tape has certain waterproof performance but cannot be fully guaranteed. Finally, PMMA, PMMA is also acrylic, which is the best quality synthetic transparent material so far. PMMA is light, inexpensive, and easy to process. It is an ideal material and is also insoluble in water.
In this way, we can conclude that the waterproof effect of PVC reflective tape is relatively clear, and it is not suitable for use in environments with strong ultraviolet rays, but it is more suitable for rainy cities. PU and PMMA have a certain waterproof effect, and they are also resistant to aging, their applicability is more extensive. If you have any questions about reflective tape, you can consult Yuhuan.
