Polycarbonate Food Grade

Overview

What is the Material: Polycarbonate Food Grade is an amorphous material with a food grade coating.

Key Material Features: This material differs from other polycarbonate in that is has FDA approval due to its food grade coating, while maintaining the properties of other polycarbonate material including transparency, high strength, hardness, and impact strength.

Other Considerations: This material may not be suitable in applications requiring diverse chemical resistance.
