The Plaskolite success story spans six decades. See how it all began.


Plastic drinking straws gave us our first taste of success.


Plaskolite introduces the "lifetime fly swatter," the must-have accessory for every front porch.


As fluorescent lighting fixtures become popular, Plaskolite begins extruding prismatic patterned lenses.


Remember the hula hoop craze? Plaskolite manufactured hula hoops in the early sixties.


Plaskolite begins producing smooth acrylic sheets for storm doors and windows; it's much safer than plate glass.


Plaskolite builds its first polymer plant, enabling us to produce our own pellets for sheet production.


With the purchase of MIR-ACRYL, Plaskolite begins producing mirrored acrylic sheet; security mirrors; and hard-coated acrylic sheet products.


Plaskolite acquires Continental Acrylics, a specialty polymers business.


The acquisition of RAM PRODUCTS' flat sheet business enables Plaskolite to begin production of 19 acrylic mirror colors.


In August, Plaskolite completes construction on a state-of-the-art 245,000 sq. ft. manufacturing facility in Zanesville, Ohio.


Plaskolite acquired Bunker Plastics, a leading manufacturer of polycarbonate mirror; formed security and transportation mirror; and performance enhancement plastic coatings.


Plaskolite acquires the continuously processed acrylic sheet division of Lucite International, including manufacturing plants in Olive Branch, Miss., and Monterrey, Mexico.


Plaskolite acquires the North American VIVAK® line of PETG sheet from Bayer MaterialScience LLC.


Plaskolite acquires the mirror sheet product line
from SPECCHIDEA s.r.l. of Torino, Italy.

OPTIX IRB - IR Blocking Acrylic


OPTIX IRB is an infrared blocking acrylic sheet that reflects solar radiation, while allowing a high level of natural light. The IR-blocking additive is in the polymer and allows OPTIX IRB to deliver exceptional IR blocking along with impact resistance and weatherability. The result: interiors benefit from natural sunlight without the heat gain. Ideal for skylights, covered walkways and conservatories.
