Types of Transparent Boards
There are several types of transparent boards, each offering unique properties for specific applications. The most commonly used materials include:

Acrylic Boards (PMMA):

Acrylic, also known as polymethyl methacrylate, is one of the most popular transparent board materials. It is known for its excellent clarity, light weight, and weather resistance.
Acrylic boards are widely used in signage, display cases, windows, and light fixtures. They offer excellent UV resistance and are available in various colors and finishes, including clear, frosted, and textured.
Polycarbonate Boards (PC):

Polycarbonate transparent boards are known for their superior impact resistance, making them a more durable alternative to acrylic. They are nearly unbreakable, offering up to 250 times the impact resistance of glass.
Polycarbonate boards are used in applications that require both clarity and safety, such as safety shields, protective glazing, and bullet-resistant windows. They also offer good UV protection and weather resistance.
PETG Boards:

PETG (Polyethylene Terephthalate Glycol) boards are another transparent plastic material that offers good clarity, impact resistance, and chemical resistance.
PETG is commonly used in medical and food packaging, as well as in displays and signage. It can also be thermoformed and is often chosen for applications where easy fabrication is important.
Polyethylene (PE) and Polypropylene (PP) Boards:

While not as transparent as acrylic or polycarbonate, certain grades of polyethylene and polypropylene can be made clear and are sometimes used for specific applications that require chemical resistance or low-cost solutions.
These boards are often used in industrial or laboratory settings and can be customized for specific transparency levels.
Applications of Transparent Boards
Transparent boards are used in a wide range of industries due to their versatility, clarity, and durability. Some of the most common applications include:
