中文简体Acrylic Sheet, also known as plexiglass, is a thermoplastic material that combines transparency, lightness, easy processing and impact resistance. It is widely used in advertising display, home decoration building materials, industrial manufacturing, transportation, art installations and other fields. However, different usage requirements have significant differences in the thickness of acrylic sheets. Correctly selecting the thickness of acrylic sheets can not only improve the use effect, but also save costs and ensure safety.
1. Common thickness range of acrylic sheets
The thickness of acrylic sheets is usually between 1.5mm and 50mm, and some special customizations can reach more than 100mm. Common thicknesses on the market are:
Thin sheets: 1.5mm, 2mm, 3mm
Medium and thick sheets: 4mm, 5mm, 6mm, 8mm, 10mm
Thick sheets: 12mm, 15mm, 20mm and above
The choice of thickness is mainly determined by load-bearing requirements, usage occasions, visual effects and processing methods.
2. Thickness recommendations for different application scenarios
1. Advertising display and light box panels
Recommended thickness: 2mm~5mm
Reason: This type of use has low load-bearing requirements, but requires good light transmittance and flatness. 3mm is a common choice for advertising light boxes, with moderate thickness and easy UV printing and screen printing.
Application examples: signboards, LED light guides, exhibition stands, POP advertising boards.
2. Furniture countertops and partition decorations
Recommended thickness: 8mm~15mm
Reason: Furniture such as coffee tables, display cabinet panels, transparent partitions, etc. require a certain degree of rigidity and impact resistance while maintaining beauty. Thick panels can better withstand external impact and are suitable for spaces that are used more frequently.
Application examples: office desks, cabinet partitions, cash register protective panels.
3. Protective covers and equipment housings
Recommended thickness: 5mm~12mm
Reason: Transparent observation windows or protective covers on mechanical equipment or automated production lines must have impact resistance to avoid fragmentation and splashing. The greater the thickness, the stronger the protection.
Application examples: laser cutting machine hood, safety baffle, industrial cover.
4. Aquarium and viewing window
Recommended thickness: 10mm~25mm (depending on the size)
Reason: Need to withstand a lot of water pressure, especially large aquarium or diving viewing window, must use thick plate and high-precision hot bending treatment on the edge.
Application examples: fish tank, hotel water feature wall, oceanarium transparent tunnel.
5. Outdoor application (wind shield, sun shed)
Recommended thickness: 4mm~10mm
Reason: Outdoor use needs to consider UV resistance, weather resistance and strong wind resistance. Generally with UV coating or use UV-resistant acrylic sheet to avoid yellowing or brittle cracking after long-term exposure.
Application examples: balcony windshield, garden partition, outdoor guide board.
6. Creative art installations or sculptures
Recommended thickness: 3mm~20mm can be selected according to the complexity of the shape
Reason: Artworks have high requirements for visual impact and structural stability. Thicker acrylic sheets can achieve more complex carving and stacking shapes.
Application examples: installation art, light sculptures, exhibition hall shape display.
3. Notes on thickness selection
The larger the size, the higher the thickness should be: if the large-sized acrylic sheet is too thin, it is easy to bend or crack, especially when it is installed in the air, it needs to be thickened.
Avoid excessive pursuit of thickness: although thicker sheets are more durable, they will also increase costs and processing difficulties, and affect light penetration.
Consideration with structure: if acrylic is used as a structural material (such as brackets and load-bearing parts), it needs to be reasonably thickened in combination with mechanical analysis.
Temperature and environmental factors: In high temperature or strong ultraviolet environment, acrylic will expand and contract slightly, and it is more stable to choose UV-resistant materials.
As a powerful material, the "thickness" selection of acrylic sheet seems simple, but it is actually related to safety, beauty and cost control. It is recommended to consider the specific purpose, installation method and budget when making the actual selection. If necessary, you can consult professional manufacturers for technical advice.
Reasonable selection of acrylic thickness to achieve a perfect balance between practicality and aesthetics of your product is a key step in achieving high-quality engineering design.
