Acrylic is an incredibly useful plastic for applications requiring transparency where high impact resistance is not an issue. Acrylic is very scratch resistant compared to other clear plastics. It is a lighter alternative to glass and an economic substitute for polycarbonate in applications where strength is not a crucial factor. It can be cut into extremely fine shapes using laser cutting technology because the material vaporizes upon impact with the concentrated laser energy. Acrylic thermoplastics are known for their outstanding weather ability. They are also characterized by good impact strength, formability, and excellent resistance to sunlight, weather, and most chemicals. Standard grades are rated as slow burning, but a special self-extinguishing grade of sheet is available. Although acrylic plastic weighs less than half as much as glass, it has many times greater impact resistance. As a thermal insulator, it is approximately 20% better than glass. It is tasteless and odourless.

Applications of Acrylic Sheets
Acrylic is generally used for a variety of applications that typically take advantage of its natural transparency and the impact resistance of certain variants. Common uses include lenses, acrylic nails, paint, security barriers, medical devices, LCD screens, and furniture. It is also often used for tanks, Industrial window glazing, safety shields, inspection windows, machine covers, and enclosures around exhibits. In merchandising, acrylic sheet has become the major sign material for internally lighted faces and letters, particularly for outdoor use where resistance to sunlight and weathering is important.
In addition, acrylics are used for counter dividers, display fixtures and cases, transparent demonstration models of household appliances and industrial machines, and vending machine cases. The ability of acrylics to resist breakage and corrosion, and to transmit and diffuse light efficiently has led to many industrial and architectural applications. Acrylics are employed to good advantage as the diffusing medium in lighting fixtures and large luminous ceiling areas. Dome skylights formed from acrylic sheet are an increasingly popular means of admitting daylight to industrial, commercial, and public buildings and even to private homes.
Acrylic Mirror is a lightweight, reflective thermoplastic sheet material used to enhance the look and safety of displays, POP, signage, and a variety of fabricated parts. Acrylic mirror is ideal for retail, food, advertising, and security applications.
A durable vacuum metalizing process makes acrylic mirror sheet virtually scratch-resistant during fabrication processes and end use. Ideal for use where glass is too heavy or may easily crack or shatter, plastic mirror is a durable alternative to traditional mirrors.
For this reason, acrylic mirror can be used to replace glass for mirrors in schools, yoga or dance studios, hospitals, prisons and jails, homes and anywhere safety is a concern.
