Acrylic

　Also known as PMMA or plexiglass, from English acrylic (acrylic plastic), chemical name is polymethylmethacrylate. It is an important plastic polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy to dye, easy to process, beautiful appearance, and widely used in the construction industry. Plexiglass products can be divided into pouring plate, extruding plate and molding plastics.

Characteristic

1. It has crystal transparency, light transmittance over 92%, soft light, clear vision, and acrylic dye with good color development effect.

2. Acrylic plate has excellent weather resistance, high surface hardness and gloss, as well as good high temperature performance.

3. Acrylic plate has good processing performance. It can be hot formed or machined.

4. Transparent acrylic plate has better transmittance than glass, but its density is only half of that of glass. In addition, it is not as fragile as glass. Even if it is damaged, it will not form sharp fragments like glass.

5. The wear resistance of acrylic plate is close to that of aluminum, with good stability and resistance to various chemicals.

6. Acrylic board has a good printability and spray, using appropriate printing and spray technology can give acrylic products an ideal surface decoration effect.

7. Fire resistance: it is not self igniting but inflammable and does not have self extinguishing property.

characteristic

1. Hardness

Hardness is one of the parameters that can best reflect the production process and technology of cast acrylic plate, and it is an important part of quality control. The hardness can reflect the purity of raw material PMMA, the weather resistance of the plate and the high temperature resistance. Hardness directly affects whether the plate will shrink, bend and deform, and whether the surface will crack during processing. Hardness is one of the hard indexes to evaluate the quality of acrylic board. The average hardness value is about 8 and 9 degrees.

2. Thickness

Acrylic tolerance exists in the thickness of acrylic sheet, so the control of acrylic tolerance is an important embodiment of quality management and production technology. There is an international standard for acrylic production

3. Transparency / whiteness

Strict raw material selection, advanced formula follow-up and modern production process to ensure excellent transparency and pure whiteness of the board. After flame polishing, it is crystal clear.

Main uses

PMMA is a kind of polymer which is polymerized by acrylic acid and its esters. The corresponding plastics are called polyacrylic plastics. Among them, polymethylmethacrylate methyl ester is the most widely used. PMMA, commonly known as plexiglass, is the best synthetic transparent material so far.

PMMA has the advantages of light weight, low price and easy forming. Its forming methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be mass production, simple process, low cost. Therefore, it is widely used in instrument parts, automobile lamps, optical lenses, transparent pipes, etc.

Advantage

Acrylic is the best new material for making sanitary wares after ceramics. Compared with the traditional ceramic materials, acrylic has the following advantages in addition to its unparalleled high brightness: good toughness, not easy to be damaged; strong repairability, as long as you dip soft foam in toothpaste, you can wipe the sanitary ware with a new one; soft texture, no cold and piercing feeling in winter; bright color, which can meet the pursuit of different grades of personality. Making basins, bathtubs and toilets with acrylic is not only exquisite and durable, but also environmentally friendly. Its radiation line is similar to the radiation level of human body's own bones.
