Product Texts

Eastman Spectar™ 14471 copolyester is a sparkling, clear plastic material that is increasingly popular for protective barriers used to limit the spread of viruses like COVID-19, including sneeze guards. For these applications, Spectar is a proven alternative to polycarbonate and acrylic.

Eastman Spectar™ copolyester is BPA free, environmentally friendly, fire and shatter resistant, long lasting, and resistant to common commercial cleaning agents. It can be found in a variety of end applications around the world, like point-of-purchase displays and other in-store fixtures; separation barriers; signs; light fixtures at retailers, schools, hospitals, and office buildings; and sneeze guards.

Facility managers prefer Spectar copolyester for its excellent fire safety, chemical resistance, and versatility. It is the only clear plastic for heavy-gauge sheet applications that passes the National Fire Protection Association’s NFP

286 flammability test, required by many regional and national building codes.
