The Difference Between PC Prototype And Acrylic Prototype

Apr 10 , 2023 | Blog

Many customers are very confused when making transparent prototypes. They don't know what transparent material to choose. It is still unclear which PC and PMMA are better and more suitable for the needs. In order to let customers know their advantages and disadvantages more clearly, the key depends on what kind of performance customers need to do. These are 2 similar materials.

PC is resistant to neutral oil, strong acid resistance, no durability, no alkali resistance. It is necessary to add UV coating, but high temperature resistance, good light effect, PC has high transparency, light weight, impact resistance, sound insulation, heat insulation, fire resistance, aging resistance and other characteristics. It is a high-tech, excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet. PC can generally withstand high temperature, the temperature is about 120 to 150 degrees.


 PMMA is a non-toxic, environmentally friendly material. It can be used for tableware, sanitary ware, etc., and has good chemical stability and weather resistance. Areas of application of acrylic acid: automotive industry (signal lighting equipment, dashboards, etc.), pharmaceutical industry (storage containers, etc.), industrial applications (DVD, light scattering). The key to electronics, especially transparent ones. Daily consumer goods (drink cups, stationery, etc.). Good optical performance: 1. Visible light: high transmittance of visible light: PMMA is currently the best transparent material, with a transmittance of 92% of visible light, HIG. Her transmittance is 2 higher than that of glass. Infrared: PMMA allows infrared transmission less than 2.8nm wavelength, and longer wavelength IR with wavelength less than 250nm is basically blocked, there is a special colored PMMA, which allows specific wavelength IR to pass and blocks visible light, for remote control or heat sensitivity. Like a TV remote.


 What are the advantages of acrylic is the most important is high transparency. 

After polishing, the transparency of the polishing paste can reach complete transparency, which is called plexiglass by the industry, which is incomparable to PC materials. PC is transparent, but it doesn't work well.


What are the disadvantages of acrylic ? 

Everyone knows that glass is very brittle. Acrylic is a kind of plexiglass, so its physical properties are also very brittle. The poor toughness of this defect will cause the acrylic to fall out inadvertently. In the prototyping process, this is a key to avoid, so it can only be replaced by B. Other materials such as PC.


 From the above information, we can see that the advantages and disadvantages of PC and acrylic are: the transparent effect of PC material is average, the toughness is good, and high temperature resistance. Acrylic has good transparent effect, poor toughness, and is not obvious at high temperature. Through the above performance, you can choose your own prototype material according to your needs, and achieve the desired effect.
