Acrylic and polycarbonate sheets have many different characteristics. These two types of plastics are often compared with each other because they are similar in appearance and are the most frequently used transparent plastic materials on the market. Both have advantages and disadvantages. Let's look at their differences in detail below.



What is acrylic and polycarbonate



Acrylic is sold under many brand names, such as Perspex, Fluorite, Perspex, Policril, Gavrieli, Vitroflex, Limacryl, R-Cast, Per-Clax, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass, Optix. In particular, "plexiglass" can almost be used interchangeably with "acrylic plastic". Although the characteristics of each branded product may be slightly different, they each form acrylic plastic.


Polycarbonate plastic

Polycarbonate is sometimes also called Lexan or Makrolon. One of the biggest differences between acrylic and polycarbonate is cost. The cost of polycarbonate sheets is on average about 35% higher than acrylic sheets.



What are acrylic and polycarbonate sheets made of

Both polycarbonate and acrylic are polymers. A polymer is simply a material composed of different molecules linked together by long chains. Therefore, the appearance, feel and behavior of polycarbonate and acrylic resin are different, depending on the specific molecular species they are composed of and how they are combined together. This entire creation process is called aggregation.


Polycarbonate is made by the reaction between bisphenol A and phosgene COCl2. On the other hand, acrylic is made by synthesizing methyl methacrylate. Methyl methacrylate is usually produced by reacting acetone with sodium cyanide to produce acetone cyanohydrin. It is then reacted with methanol to finally produce methyl methacrylate.


These are the most common methods for preparing these polymers. However, a variety of methods can be used to form polycarbonate and acrylic, especially when making plastic sheets with special qualities, such as color, anti-glare, anti-static, and ultraviolet filtering.



How to produce acrylic plastic board

Batch and continuous bulk polymerization are two methods of making acrylic plastic plates.

Intermittent batteries are the most common form of bulk polymerization because it can effectively produce acrylic plates with a thickness of 0.06 to 6.0 inches and a width of 3 feet to several hundred feet. The continuous method of bulk polymerization is faster and less labor intensive because it is specifically used to manufacture acrylic sheets with a thickness that is thinner and smaller than the batch processing unit can produce.



How are polycarbonate sheets made

Polycarbonate can be processed and manufactured in many ways, such as extrusion, injection molding, blow molding, thermoforming, etc. However, in the production of polycarbonate sheets, the extrusion manufacturing process is most commonly used. First, feed the raw resin (polycarbonate pellets) into the extruder and melt to the desired temperature. The molten polycarbonate material is then pressed through a mold, which is shaped to produce flat plates of various lengths, widths and thicknesses with uniform cross-sections.


In this process, polycarbonate sheets can be produced in the form of color, high or low gloss, smooth or textured surfaces, and single-layer or multi-layer forms. Once the polycarbonate sheet is manufactured through the extrusion process, it can be further processed to obtain the desired final product.
