DENTAL PLASTER – TYPE 4
Gorget Company · source
Dental Plaster Type 4, is defined as an extra hard stone for dies, composed form refined raw materials selected with high strength. It perfectly combines high compressive strength and smooth surface and is extremely accurate. They are used mainly in the preparation of dies for fixed prosthesis, chrome models, and making bases. They must have high resistance to compression and abrasion.
