Which is better, organic glass sheet or cast acrylic sheet? Teach you selection techniques
Which is better, "organic glass board" or "cast acrylic board"? This is the most common question asked by many buyers.
The answer is actually very simple: the two are essentially the same, there is no absolute good or bad, the key is to see the purpose. Organic glass and acrylic are both PMMA materials, with "organic glass" being a free translation and "acrylic" being a transliteration. The true determinant of quality is the production process - "casting" or "extrusion".
The casting board has higher quality and better performance, suitable for high-end scenarios; The extruded board has outstanding cost-effectiveness and is suitable for large-scale standardization needs. This article will help you make the most suitable choice from three dimensions: differences, specifications, and selection techniques.
The core difference lies not in the name, but in the craftsmanship:
Comparison Dimension Casting Plate Extrusion Plate
Production process: slow injection of liquid monomers into molds, polymerization of granular raw materials, melting and continuous extrusion
Light transmittance 92% -98%, approximately 92%
Molecular weight>1 million g/mol, approximately 600000 g/mol
High hardness, moderate scratch resistance, and greater flexibility
Outdoor weather resistance: 5-10 years without yellowing, average
Excellent chemical resistance, moderate
The color customization is extremely high, with limited flexibility for small batches and adjustable only for large batches
Processing adaptability: Laser/CNC/engraving is better, hot bending/vacuum forming is better
Higher and lower price (about 30% lower)
Important reminder: Some people in the market refer to all transparent plastic boards (including PS boards, PC boards, etc.) as "organic glass". If you buy PS board as acrylic, its performance will be much worse. Therefore, emphasizing "cast acrylic" or "PMMA cast board" in professional procurement means a double high standard requirement for raw material purity and production process.
Mainstream specifications of cast plates
Applicable scenarios for thickness standard dimensions
1.8-5mm 1220 × 2440mm advertising signs, light boxes, display props
8-15mm 1220 × 2440mm building decoration and industrial accessories
20-200mm can be customized to 3000 × 9000mm aquariums and large-scale projects
The thickness of the casting board covers 1.8mm to 200mm, and some manufacturers can form 2mm-200mm at once. The maximum composite thickness can reach 750mm. Standard colors include transparent, white, black, red, green, blue, yellow, etc., and OEM color customization is supported.
The mainstream specifications of extruded boards
Applicable scenarios for thickness standard dimensions
2-10mm 1220 × 2440mm large batch lightbox panel
1-20mm 1250 × 2050mm vacuum forming
12-20mm non-standard customizable hot bending products
The thickness of extruded plates is usually 2-10mm, and non-standard thicknesses can reach 1mm and 12-20mm. The thickness tolerance is smaller than that of cast plates, making it suitable for large-scale standardized production.
Q1: Which is better, organic glass sheet or cast acrylic sheet?
There is no absolute good or bad. The quality of the cast board is higher - with a light transmittance of 92% -98%, no yellowing for 5-10 years outdoors, and the color can be customized freely; Extruded boards offer higher cost-effectiveness - about 30% lower price, smaller thickness tolerance, and suitable for large-scale production. The key is to consider the purpose.
Q2: How to determine whether to choose cast board or extruded board?
Ask yourself three questions:
Is it used outdoors or indoors? Outdoor casting board (UV resistant, 5-10 years without yellowing)
Is there a high requirement for transparency? High demand casting board selection (92% -98%)
Do you need customized colors or small batches? Need to choose casting board (flexible color)
Q3: How to avoid buying PS boards as acrylic?
It can be quickly distinguished by combustion testing: taking a small piece of scrap and igniting it with fire, PS board will produce a large amount of black smoke when burned, while acrylic board will have no black smoke when burned. In addition, the transparency of PS board is average, and there may be speckles when reflecting, which are relatively brittle and prone to breakage.
Q4: What is the thickness tolerance of the casting plate?
Due to the characteristics of the production process, there may be a certain thickness tolerance for cast plates. As the thickness increases, the tolerance will also increase accordingly. The thickness tolerance of the extruded board can be controlled within ± 0.1mm. It is recommended to confirm the thickness tolerance range with the manufacturer in advance when purchasing.
Q5: What is the approximate price of the casting board?
The price of cast plates is usually higher than that of extruded plates. Taking 5mm domestically produced casting board as an example, it costs about 70 yuan/㎡; An 8mm cast board with UV coating for long-term outdoor use costs approximately 100 yuan per square meter. As the source factory, Zhejiang Yifang can offer a price that is over 30% lower than the market for the same quality.
