Multilayer – naturally colored polymers
Highly crosslinked acrylic polymer
DD poly X ML are highly cross-linked multilayer blanks for CAD/CAM milling based on polymethyl methacrylate (PMMA). Five color layers ensure a natural and aesthetic effect.
Benefits
- Biocompatible – medical polymer material
- Very high hardness and abrasion resistance
- Good polishing properties
- Customizable with composite
