Which plastic material is as transparent and beautiful as the glass?

 The CNMOULDING recommendation must be a PMMA

transparent plastic material


Organic Glass (Polymethyl methacrylate) is a popular name, abbreviated to the PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic. Plexiglass is divided into colorless transparent, colored transparent, bead light, pressed flower plexiglass. Perpoxiglass is commonly known as acrylic, medium publicity pressure acrylic, acrylic, plexiglass has good transparency, chemical stability, mechanical performance and weather resistance, easy to dye, easy processing, beautiful appearance, and other advantages. Plexiglass is also called gelatin glass, acrylic, etc. 

Organic glazing is widely used, 

Not only in the business, light industry, construction, chemical industry, and so on. And Plexiglass production, in advertising decoration, sand table models are widely used, such as signs, billboards, lightbox panels, and Sino - English letter panels. 

Material selection depends on the modeling design, what kind of modeling, with what kind of organic glass, color, variety should be tested repeatedly, so that it to achieve the best effect. With a good modeling design, but also rely on careful processing, in order to become a beautiful handicraft. 

1. building application: window, sound-proof doors, and windows, lighting cover, telephone booth, etc

2. Advertising application: lightbox, signboard, signs, display frame, etc

3. traffic application: doors, windows of trains, cars, and other vehicles

4. medical application: baby care box, various surgical medical appliances, civilian supplies: sanitary ware facilities, crafts, cosmetics, stents, aquariums, etc. 

5. Industrial application: instrument surface plate and protective cover, etc. 

6. Lighting Application: fluorescent lamp, chandelier, street hood, etc

7. home application: fruit plate, paper towel box, acrylic art painting, and other household daily products

Machinery

Plexiglass has the above excellent performance, making it extremely widely used. In addition to being used on aircraft as a cockpit cover, windscreen window, it is also used as the windshield and windows of the Jeep, sunroof (anti-breakage), screens for television and radar, shields for instruments and equipment, the housing of telecommunications instruments, telescopes and optical lenses on the camera. 

There are many kinds of daily necessities made of organic glass, such as buttons made of bead light organic glass, all kinds of toys, lamps are also because of the decorative effect of stained organic glass, and appear particularly beautiful. 

Medical care

Plexiglass also has a wonderful medical use, that is to make artificial corneas. If the transparent cornea of the human eye is covered with opaque substances, the light can not enter the eye. This is the blindness caused by a total corneal leak and the disease cannot be treated with medication. 

Therefore, medical scientists imagine using the artificial cornea instead of the cornea covered with white spots. The so-called artificial cornea is to use a transparent material into a mirrored column with a diameter of only a few millimeters and then drill a small hole in the corner of the human eye, the mirror column fixed on the cornea, the light through the mirror column into the eye, the human eye can again see the light. 

As early as 1771, ophthalmologists implanted their corneas with optical glass, but not successfully. Later, using crystal instead of optical glass, also became ineffective for only half a year. In World War II, some aircraft were wrecked when cockpit covers made of plexiglass were blown up and fragments of it were embedded in the pilot's eyes. After many years, although the fragments were not removed, there were no further causes of human eye inflammation or other adverse reactions. This accidental event indicates good compatibility between Plexiglass and human tissue. At the same time, it also inspires ophthalmologists who can use organic glass to make an artificial cornea. It has good light transmittance, stable chemical properties, non - toxic to the human body, easy to process into the desired shape, and can be compatible with the human eye for a long time. Artificial corneas made from plexiglass have been commonly used in clinical practice.
