Plexiglass, which is a common name, also has a trade name called "Acrylic", whether it is the name of the product "acrylic" or the popular name "plexiglass", which is actually not accurate. This material looks very beautiful, its official name is: polymethyl methacrylate. This is a thermoplastic that has been invented very early and has a long history.
How bright is acrylic in the end? Here we introduce a concept called "light transmittance", which we usually call "transparency", which can be simply understood as high light transmittance.
Ordinary glass (glass, etc.), the light transmittance is basically above 80%, the transmittance of ultra-white glass is between 91% and 93%, and the transmittance of acrylic is above 92%.
How is it, is it very powerful? Although it is not glass, it is more transparent than ordinary glass.
Second, acrylic is also very "hard."
We introduce a materialistic concept of "hardness", which usually has many representations and methods (like temperature in degrees Celsius and Fahrenheit). Among them, "Mohs hardness" is widely used, and we usually call the hardest "diamond", which has a Mohs hardness of 10.
Ordinary iron, Mohs hardness is about 5, while ordinary stainless steel and glass have similar Mohs hardness, both above and below 5.5 (the hardness of special steel such as high carbon steel is much higher, stainless steel is not characterized by hardness, hardness And intensity is two things, and future articles will continue to introduce), but the hardness of polymethyl methacrylate can reach 8 or even 9.
It is precisely because of the characteristics of acrylic, so in some occasions that need to be decorated with glass, acrylic will show its talents, but also ensure the beauty, but also avoid the fragility of the glass, and because the acrylic density is almost half of the glass, it can be greatly reduced. Structure weight.
