Black polycarbonate lexan sheets can be used for a variety applications, especially those heavy-duty applications that require added strength needed in a plastic sheet product. Polycarbonate can be used for storage shelves, machine guards, merchandise displays, structural parts, fabricated components, robotics, and in other demanding applications. Polycarbonate can be formed and machined, including drilling holes, sawing and routing.
Our black polycarbonate sheets are opaque (0% light transmission) and has a glossy finish on both sides.
We carry black polycarbonate sheets in a variety of pre-cut sizes to satisfy the needs of many DIY projects, fabrication, or commercial construction projects. Select the thickness you need to find the sheet or sheets for your next project. We can also cut to size.
Key Characteristics of Black Polycarbonate:
The Term lexan is commonly used to describe polycarbonate. Actual name brand will depend on current stock.
