What is acrylic? What material is acrylic?

What is acrylic board? Acrylic sheets are polymerized from methyl methacrylate monomer (MMA), which is polymethyl methacrylate (PMMA) sheet plexiglass. "plexiglass" is derived from the product "Oroglas" (a PMMA sheet), which is From "OrganicGlass" (ie organic glass).

What is acrylic?

Acrylic is an important thermoplastic that was developed relatively early. It has transparency, weather resistance and stability, is easy to process, is easy to dye, and has a beautiful appearance. It is used in construction It is widely used in the industry and is a commonly used glass substitute material.

In the construction industry, acrylic is mainly used in lighting bodies, stairs, roofs, ceilings and indoor wall sheathing. In recent years, acrylic has also been widely used in highway lighting shades and automotive lamps.

With the construction of hotels, guesthouses and high-end residences in big cities, lighting bodies have developed rapidly. Lighting bodies made of acrylic have the characteristics of high overall structural strength, light weight, strong light transmittance and high safety performance. , compared with ordinary glass lighting devices, it has great advantages.

In terms of sanitary ware, acrylic can be used to make bathtubs, dressing tables, wash basins and other products. Acrylic bathtubs have been widely used in recent years due to their luxurious appearance, easy cleaning, depth, light weight, high strength and comfortable use.

Advantages and Disadvantages of Acrylic Materials

Advantages:

Acrylic is the best new material for manufacturing sanitary ware after ceramics. Compared with traditional ceramic materials, in addition to its unparalleled high brightness, acrylic also has the following advantages: good toughness, not easy to break; strong repairability, just use soft foam dipped in toothpaste to wipe the sanitary ware as new; soft texture, durable in winter There is no cold and biting feeling; the colors are bright and can meet the individual pursuits of different tastes. Using acrylic to make basins, bathtubs, and toilets is not only exquisite in style and durable, but also environmentally friendly. Its radiation is almost the same as the radiation of the human body's own bones. Acrylic sanitary ware first appeared in the United States and has occupied more than 70% of the entire international market.

Disadvantages:

Due to the difficulty and high cost of acrylic production, there are many low-quality and low-cost substitutes on the market. These substitutes are also called "acrylic", which are actually ordinary organic boards or composite boards (also known as sandwich boards). Ordinary organic boards are cast with ordinary organic glass cracking materials and pigments. The surface hardness is low, easy to fade, and the polishing effect is poor after grinding with fine sand. The composite board only has a thin layer of acrylic on the surface and ABS plastic in the middle. It is prone to delamination due to thermal expansion and contraction during use. True and false acrylic can be identified from the subtle color difference and polishing effect of the plate cross section.

Classification of Acrylic Boards

Cast Acrylic Boards: High molecular weight, excellent stiffness, strength and excellent chemical resistance. This kind of board is characterized by small batch processing, unparalleled flexibility in color systems and surface texture effects, and complete product specifications, suitable for various special purposes.

Acrylic extruded board: Compared with cast board, extruded board has lower molecular weight and slightly weaker mechanical properties. However, this feature is beneficial for bending and thermoforming processing, and is beneficial for rapid vacuum molding when processing larger sheets. At the same time, the thickness tolerance of extruded panels is smaller than that of cast panels. Since extruded boards are produced automatically in large batches, the color and specifications cannot be adjusted, so the diversity of product specifications is subject to certain restrictions.

The material classification of acrylic boards is mainly divided into three categories in China: one is imported boards; the other is Taiwan-funded boards; and the third is domestic boards. The difference lies in the origin and (MMA) purity of the raw materials used. This is also the key to determining the quality and price of the board.
