Protech Elite Retainer Material, Super Clear, .030" (0.75 mm), 5x5" Square Sheets, Pack of 20

This vacuum-forming retainer material is super clear and measures .030 inches (0.75 mm) thick, ideal for fabricating orthodontic retainers. Each 5x5 inch square sheet is designed for use with vacuum forming machines; acrylic adheres well to the material, but it can bubble if overheated. Recommended technique: heat until a 1/2 inch droop occurs, then trim with a wheel saw.
