Is PC reflective tape resistant to aging?

When purchasing reflective tape, in addition to determining the desired grade and reflective intensity, it also depends on the material of the reflective tape. Good materials will not turn yellow or fade so easily, and can last longer. PC is one of the substrates of reflective tape. Today, I saw someone asking if PC reflective tape is resistant to aging. Let’s answer this question.

PC is a carbonated polyester, an almost colorless glassy amorphous polymer with good optical properties. PC is resistant to weak acids and alkalis, but not to strong acids and ultraviolet light. It will turn yellow when exposed to ultraviolet light for a long time. In this way, it seems that the reflective tape made of PC is not very good, but since it can be selected as the base material of the reflective tape, it must have certain advantages in itself. PC has high impact resistance and high refractive index, which is a very important point for its selection. The high refractive index can take advantage of the reflective material inside the reflective tape. In addition, PC has good processing performance and scratch resistance, which is also very popular. Moreover, although PC materials are not UV resistant, they have good oxidation resistance, weather resistance, dimensional stability, and almost no change under high temperature conditions. The modified PC has good outdoor long-term aging properties.

Therefore, the PC reflective tape is still very resistant to aging, and the product of this material can also be dyed freely. Kunshan Yuhuan Package Materials Co., Ltd. has many years of experience in the production and processing of various reflective products, and is an excellent choice for purchasing reflective tape.
