What is plexiglass, for example, what is plexiglass

"Plexiglass" is derived from the trade name "Oroglas", which means "organic glass". As mentioned earlier, "Oroglas" is a type of PMMA sheet, i.e. acrylic sheet. Some people think that transparent plastic sheets are plexiglass, in order to avoid confusion and mistakes, most of them now call PMMA sheets acrylic sheets, and all kinds of PMMA materials are called acrylic or acrylic.

Plexiglass acrylic sheet (acrylic sheet) species.

Acrylic sheet (acrylic sheet) is divided into cast sheet and extruded sheet according to the polymerization process, among which the cast plate has a higher molecular weight, more rigidity and more crack resistance, so it is more suitable for processing large-size signs. In addition, the caster is more suitable for producing small batches of plates of different colors. The extruded plate has low molecular weight and high flexibility, which is suitable for vacuum blister molding.

The extrusion process can better control the thickness of the plate, and the production of large quantities of monochrome plates is better.

Plexiglass acrylic sheets can be divided into pure transparent plates, color transparent plates, translucent plates (such as milky white boards) and opaque plates (such as color plates) according to light transmittance; According to the surface gloss, it can be divided into high-gloss board, mercerized board and matte board (also known as frosted board); According to the characteristics, acrylic plate can also be divided into ordinary plate, anti-ultraviolet plate, anti-ultraviolet plate, flame retardant plate and high wear-resistant plate and so on.

Plexiglass acrylic (acrylic) is the transliteration of English acrylic, is the general term of acrylic acid and methacrylic acid chemicals, people often say that acrylic sheet is polymethyl methacrylate (PMMA) sheet, which is made of methyl methacrylate monomer (MMA) polymerization.

A brief history of plexiglass acrylic (acrylic) As early as the 20s of this century, Rohm and Ha Xin first invented the method of polymerizing into acrylic sheets with MMA, which was later called "Oroglas plexiglas". However, the company was unable to find a more economical process route for the production of MMA, so the acrylic sheet was not widely used at that time.

In 1931, the scientists of ICI invented the acetone cyanohydrin method for the production of MMA, which greatly reduced the cost of MMA and popularized acrylic sheets. At the same time, ICI also successfully developed acrylic sheets for cockpit roof covers for fighter jets, and subsequently built the world's largest acrylic sheet factory in the UK.

Plexiglass will not hurt people when it is broken, so the coffee table and wine cabinet at home should be made of plexiglass, which is green in color from the facet.

We often hear the word "plexiglass" in life, and various items made of plexiglass are also used in all aspects of our lives.

1. What is plexiglass?

Plexiglass is a polymer made from the polymerization of methyl methacrylate, which is chemically known as polymethyl methacrylate. Plexiglass is a synthetic plastic product and is a thermoplastic. Its surface is relatively smooth to the touch, looks colorful, and the light transmittance is also very good, it is very light, very strong, good sound insulation, both moisture and sun resistance, and has strong corrosion resistance.

Many objects nowadays are made of plexiglass, usually translucent, colored objects.

2. The difference between plexiglass and ordinary glass.

Although the two are very similar in appearance, both are colorless and transparent, but their composition and properties are completely different. The main component of ordinary glass is silicate double salt, which is an amorphous inorganic non-metallic material, which is brittle and has poor impact resistance, and can only be made into products that do not have particularly high requirements for heat resistance and impact resistance. Plexiglass has a wide range of applications because of its good heat resistance and impact resistance.

3. The difference between plexiglass and tempered glass.

Plexiglass is a plastic product, which is synthesized by man; The tempered glass is made of ordinary glass, and after the ordinary glass is tempered, it becomes tempered glass. Plexiglass is characterized by light weight, good toughness or toughness, bending resistance, impact resistance and wear resistance, and it is also easy to be processed, so it is very widely used; Tempered glass has good strength and wear resistance, but it is very heavy, and can not be reprocessed, the impact resistance of the surrounding side end face is also very weak, and there is a chance of self-explosion, tempered glass is generally made into bulletproof armor, and can also be made into doors and windows of high-rise buildings and so on.

I conclude: plexiglass, ordinary glass and tempered glass are glass, but the characteristics of the three are very different, when choosing glass products, we must choose the right one according to their own needs.

Plexiglass is a polymer transparent material. The chemical name of plexiglass is polymethyl methacrylate, commonly known as acrylic, gelatin glass, and acrylic, which is an important thermoplastic developed earlier. Plexiglass has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance.

Plexiglass is divided into four types: colorless transparent, colored transparent, pearlescent, and embossed plexiglass.

Colorless transparent plexiglass: it is the most common and most used plexiglass material; Colored transparent plexiglass: commonly known as color plates.

The light is soft and translucent, and the light boxes and handicrafts made of it make people feel comfortable and generous. Magnetic organic Mingwu glass luster and/or not as bright as pearlescent Huai which machine glass is bright, brittle, easy to break, suitable for making dials, boxes, medical equipment and people, animal modeling materials.

Pearlescent plexiglass: It is made by adding pearlescent powder or phosphor to general plexiglass. This kind of plexiglass has bright color and high surface finish, and the outer form is hot-pressed by the mold, even if it is smoothed and polished, it still maintains the molded pattern and forms a unique artistic effect.

Embossed plexiglass: it is transparent, translucent and colorless, brittle, easy to break, used in interior doors and windows and other decorations, with the characteristics of both light transmission but opaque, usually used in indoor partitions or indoor doors and windows.

Plexiglass is a colloquial name abbreviated as 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 hand plastic that was developed earlier.

Plexiglass is divided into four types: colorless transparent, burning-colored transparent, pearlescent, and embossed plexiglass. Plexiglass is commonly known as acrylic, acrylic, agri, plexiglass has the advantages of good transparency, chemical stability, mechanical properties and weather resistance, easy dyeing, easy processing, and beautiful appearance. Plexiglass is also called gelatin glass, acrylic, etc.
