Plexiglass plate, 3MM thick, the manufacturer said that adding anti-ultraviolet raw materials can ensure that 18 months will not change color. How long can a normal life last? I use it as a light box.
General light boxes are made of acrylic (plexiglass). The reason why it is better than PC is that acrylic is acid-resistant, alkali-resistant and salt-resistant, and its outdoor weather resistance is better. Generally, acrylic does not contain recycled materials (recycled acrylic), so it is normal to ensure that it will not change color for 3 or 5 years. I'm afraid it is false to say that ultraviolet raw materials are added. I fooled you, an amateur. Satisfied answer, give me extra points.
