What is acrylic?
Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic), and its chemical name is polymethyl methacrylate.
It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance. It is easy to dye, easy to process, and has a beautiful appearance. It has a wide range of applications in the construction industry. Divided into cast plate, extrusion plate and molding compound.
Basic characteristics of acrylic
1. Acrylic has high transparency and clear vision, which can reach a light transmittance of more than 92%. The light transmittance of ordinary glass is only about 85%, which can achieve the transparency of optical glass, even after dyeing. transparency, which increases the display and aesthetics of the acrylic.
2. Acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.
3. The acrylic sheet has good processing performance, either by thermoforming or by machining. The machining accuracy depends on the machine itself and the experience of the technicians.
4. The transparent acrylic sheet has a light transmittance comparable to that of glass, but the density is only half of that of glass. In addition, it is not as brittle as glass, and even if broken, it will not form sharp shards like glass.
5. The wear resistance of acrylic sheet is close to that of aluminum, with good stability and corrosion resistance to various chemicals.
6. Acrylic sheets have good printability and sprayability. With proper printing and spraying processes, acrylic products can be given an ideal surface decoration effect.
7. Acrylic plate flame resistance: it is not self-igniting but is flammable, and does not have self-extinguishing properties.
8. Acrylic material can be recycled: The waste acrylic can be returned to the furnace to remove impurities and add raw materials to make acrylic sheets for sale.
What are the characteristics of high-quality acrylic material?
When any material enters the manufacturing field, there will be advantages and disadvantages, so that under the blessing of price cost and manufacturing process, it will show different qualities.
The same is true for high-quality acrylic materials. We found that high-quality acrylic materials can focus on the following aspects:
1. Material purity and transparency
Under normal circumstances, the purity of imported acrylic materials is 20% higher than that of domestic ones, and the transparency is 15% higher. The industry reputation is that they will not change color and do not turn yellow for 10 years, while domestic materials, some of which are recycled synthetic materials, are easy to fade, and the transparency is turbid, 1- Yellowing occurs in 2 years.
2. Equipment cutting accuracy
The customization and manufacture of acrylic materials are inseparable from machines. The precision of the machine is also an important part of determining the quality of acrylic customization. Usually high-end equipment integrates cutting and grinding, mechanical operation, and the accuracy is 20% higher than that of ordinary equipment, while ordinary equipment, if manual measurement is used, the product tolerance is large, the size of each piece cannot be accurate, and the cutting burr treatment is sufficient. fine.
3. The material is durable
High-quality acrylic products are usually resistant to high temperature and ultraviolet rays, and will not deform and change color for 3-5 years. They are environmentally friendly and beautiful.
Due to the difficulty and high cost of acrylic production, there are many low-quality and cheap substitutes on the market. These substitutes are also called "acrylic", but they are actually ordinary organic boards or composite boards (also known as sandwich boards). Poor polishing after sanding. The composite board only has a thin layer of acrylic on the surface, and the middle is ABS plastic, which is easy to delaminate due to thermal expansion and contraction during use.
Real and fake acrylic can also be identified from the subtle color difference and polishing effect of the sheet section.
