Polycarbonate (Lexan)

DESCRIPTION

Polycarbonate, PC, is the go-to clear substrate for security applications.  Due to its excellent impact toughness, it can be fabricated into sales counter shields, machine guards, riot shields and containment vessels.  At room temperature it can be easily cold formed with a press break.  Injection molded polycarbonate is the plastic used for every eyeglass lens and automobile headlight.  Without protection from UV rays, it is vulnerable to yellowing, as can be seen on many older cars.  PC requires an additive or coating for long term UV exposure.  It can also be treated with abrasion resistant, AR, coating to resist scratching.  For bullet proof glazing, polycarbonate sheet is laminated for extreme security situations.  Polycarbonate is available in an array of sheet gages, sizes, and colors.  Next time you want to solve a security issue, call Meyer Plastics to add impact to your project!

NOTE: Lexan® is the number one brand for polycarbonate.  So successful, the brand is better known than the generic name, polycarbonate.  We supply Palsun® UV2 made by Palram Americas.  UV2 designates Ultraviolet protection on both sides of the sheet.  We also supply Polycarbonate sheet from Gallina branded PoliComp®.  Both are manufactured in the USA.

Meyer Plastics has extensive experience fabricating and forming polycarbonate products to our customer specifications.  We are available for project planning, sampling for feasibility, and prototype parts to prove new production concepts.
