Multilayer – naturally colored polymers
Highly cross-linked acrylic polymer
DD poly X ML are multilayer, highly cross-linked CAD/CAM milling blanks 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
