PC board or acrylic board which has longer service life?
The service life of PC board and acrylic board is affected by a variety of factors, and the service life of PC board may be longer under normal circumstances. Here's a breakdown:
Material property
The main component of the PC board is polycarbonate, which has excellent impact resistance, can withstand greater external force and is not easy to break, and has good heat resistance and cold resistance, can maintain stable physical properties in a wide temperature range, and is not easy to deform for long-term use.
The main component of acrylic plate is polymethyl methacrylate, its impact resistance is not as good as PC board, easy to crack or break. However, the acrylic sheet has good weather resistance and can resist a certain degree of ultraviolet erosion and climate change in the outdoor environment.
Use environment
PC board is suitable for places with high safety performance requirements, such as building lighting roofs, highway noise barriers, etc. In the outdoor environment, if the PC board uses anti-ultraviolet additives, it can effectively delay aging, and the service life can reach 10-20 years. In the indoor environment, it is not affected by ultraviolet light and harsh weather, and its service life can be longer.
Acrylic sheet is often used in interior decoration, advertising light box and other fields. In an indoor environment, its service life is usually 5-10 years. However, in the outdoor long-term exposure to the sun, the acrylic sheet is prone to yellowing, fading, embrittlement and other phenomena, and the service life may be shortened to 3-10 Years.
maintenance
PC board is relatively easy to maintain, daily only need to clean dust and stains regularly. Due to its high surface hardness, it is not easy to be scratched, but care should be taken to avoid scratching with sharp objects.
The surface hardness of the acrylic sheet is low and it is easy to be scratched, so special care is needed during maintenance. At the same time, acrylic plate is more sensitive to organic solvents, should avoid contact with such substances, so as not to cause surface corrosion.
In summary, the PC board will have a longer service life in most cases. However, the actual service life needs to be determined according to the specific product quality, use environment and maintenance conditions.
