PMMA acrylic characteristics
PMMA is commonly known as plexiglass, also known as acrylic or acrylic. Most people in Hong Kong are called acrylic. It is an important thermoplastic developed earlier. It has good transparency, chemical stability and weather resistance. It is easy to dye and easy to dye. Processing, beautiful appearance, has a wide range of applications in the construction industry. Plexiglass products can generally be divided into cast plates, extruded plates, and molding compounds.
The transparency of plexiglass exceeds that of ordinary glass. It has a transmittance of 93% and has the brilliance of crystal glass. The acrylic (acrylic) colored with dye has a good color spreading effect.

Acrylic sheet (acrylic sheet) has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance. Acrylic sheet has good processing performance. It can be used for thermoforming (including compression molding, blow molding and vacuum suction), as well as mechanical drilling methods such as drilling, turning, cutting, etc. Microcomputer-controlled mechanical cutting and engraving not only greatly improves the processing accuracy, but also can produce patterns and shapes that cannot be completed by traditional methods. In addition, acrylic boards can be laser cut and laser engraved to produce products with strange effects.
Transparent acrylic sheet has transparent luminosity comparable to glass, but its density is only half that of glass. In addition, it is not as fragile as glass, and even if broken, it does not form sharp fragments like glass. The abrasion resistance of the acrylic board is similar to that of aluminum, and it is resistant to a variety of chemicals from time to time. Acrylic boards have good printability and sprayability. Adopting appropriate printing (such as silk screen) and spraying processes can give acrylic products (acrylic products) an ideal surface decoration effect.
The specially modified acrylic sheet can absorb a large amount of ultraviolet light. In addition, smoldering acrylic (acrylic) can still help to overcome the fire hazards in specific places. The high stamping acrylic impact strength is 6 to 10 of acrylic. Times, the ultra-wear-resistant acrylic board with a specially treated surface can withstand extremely severe tests.
Acrylic sheet is light, only half the weight of ordinary glass, specific gravity (1.19-1.20).
Milk board and white board It has good light and weather resistance, and can be used outdoors for a long time regardless of high or low temperature areas.
The surface hardness of 板 acrylic board is like aluminum alloy, which is harder than other plastics but cannot withstand the friction of steel, ceramics and glass.
Acrylic board has colorless transparent board, colored transparent and opaque board, milky white and white board, blackboard.
Thickness from 2mm to 100mm.
