Low Birefringent (OC-LB) Film

Grafix Plastics’ OC-LB Grade film is the optical designation for our acetate film. Grafix acetate is a high-clarity, optical-grade, solvent-cast polymer film that is ani-isotropic – meaning it has low internal birefringence < 25nm. Its combination of availability, environmental friendliness, and price point make it an excellent and cost-effective alternative to TriAcetate (TAC) films, Cast Polycarbonate, and other exotic (and expensive) optical films.

For more information on this film, please visit our general acetate film product page.
