Polycarbonate Food Grade
Overview
What is the Material: Polycarbonate Food Grade is an amorphous material.
Key Material Features: This material differs from other polycarbonate in that is has FDA approval, 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.
