Why is PMMA so valuable?

The high application value of PMMA(polymethyl methacrylate) is mainly attributed to its excellent performance characteristics and a wide range of application fields. The following is a specific explanation of its high application value:

First, excellent performance characteristics

High transparency: The light transmittance of PMMA can reach 92% and even higher to 94%, so that it can clearly show the color of the product and improve the visual effect. This characteristic gives it a significant advantage in situations where high transparency is required, such as advertising display, electronic product protection, etc.

Weather resistance and ultraviolet resistance: PMMA has strong resistance to ultraviolet light and atmospheric environment, and can be exposed outdoors for a long time without easy degradation or aging. This makes it excellent in applications such as outdoor billboards and building lighting roofs.

Mechanical properties: Although PMMA is relatively brittle, it is much tougher than glass and has excellent impact resistance. This makes it useful in applications that require a certain degree of strength and durability, such as car Windows and furniture surface coverings.

Machinability: PMMA is easy to process, can be processed by injection molding, extrusion and other ways, but also can be cut, drilling, bending and bonding and other secondary processing. This ease of processing allows PMMA to meet the needs of a wide range of complex shapes and sizes.

Chemical stability: PMMA has good resistance to many chemicals, but can be dissolved by some organic solvents such as carbon tetrachloride, benzene, toluene, etc. This requires that care be taken to avoid contact with these solvents during use.

Second, a wide range of applications

Construction field: PMMA is widely used in the production of lighting roofs, heat insulation panels, Windows and other building materials. Its high transparency and weather resistance make the interior of the building brighter and more comfortable, while maintaining the appearance of beauty for a long time.

Advertising: Transparent PMMA becomes the material of choice for high-quality billboards and signs. Its high transparency and excellent weather resistance allow advertising content to remain clear and vivid for a long time.

Electronic products: PMMA is increasingly widely used in electronic products, such as mobile phone screens, touch screens, displays, etc. Its high transparency and scratch resistance protect the screen from scratches and external impacts while ensuring a clear display.

Medical devices: PMMA's biocompatibility and low toxicity make it an important choice for medical devices and pharmaceutical packaging. In the medical field, PMMA is used to manufacture transparent medical device protective films, packaging materials, and medicine bottles.

Other fields: PMMA is also used in automobile manufacturing, lighting equipment, furniture production and other fields. Its lightweight characteristics, high transparency and weather resistance make it a wide range of applications in these fields.

In summary, the reason why PMMA has such high application value is that it has a variety of excellent performance characteristics and a wide range of application fields. With the continuous progress of technology and the continuous expansion of the market, the application prospect of PMMA will be broader.
