Technical DataSheet | Supplied by Evonik

VESTAKEEP® DC4420 G by Evonik is a white pigmented, high viscosity, high performance polyether ether ketone (PEEK) grade (supplied as cylindrical pellets). It is a biomaterial exhibiting superior mechanical-, thermal- and chemical resistance. Possesses outstanding wear comfort, excellent biostability and shock absorption capability. It can be processed by common melt processing techniques like injection molding and extrusion. Provides an innovative, metal-free solution in dental sector for applications like removable & fixed dentures (providing gentleness and benefit to antagonist as well as to jaw joint) and crowns & bridges suited for permanent contact with mucous membrane (it doesn’t have an unpleasant sensation of hot/ cold).
