1, raw materials and light transmittance are different: PVC board is mainly PVC, with poor light transmittance, usually translucent or opaque, and the color may be slightly yellowish, while acrylic board is PMMA (polymethylmethacrylate), which is usually completely transparent, with light transmittance above 92%, and looks crystal clear.
2. The sound is different from the burnt smell: when struck by hand, the sound of acrylic board is crisp and the sound of PVC board is dull. When burning, the flame of acrylic board is yellow, alcoholic and smokeless, while the flame of PVC board is green, smelling of hydrochloric acid and emitting white smoke.
3. Different densities and uses: The density of PVC board is 1.38g/cm? The density of acrylic board is 1. 1g/cm? Therefore, acrylic board is usually lighter than PVC board. PVC board is widely used in building materials, packaging, medicine and other fields, such as exhibition stands, water tanks, exhaust pipes and so on. Acrylic board is widely used in architecture, lighting engineering, industry, medicine and other fields, such as doors and windows, instrument covers, lampshades, light boxes and so on.
4. Different environmental protection: Acrylic is usually better than PVC in environmental protection, but some manufacturers may add plasticizers to the formula. If the plasticizer is not selected properly, it may be harmful to human body. PVC board is easy to decompose during processing and has poor stability.
5, the price is different: PVC board is usually cheaper than acrylic board.
