VESTAKEEP® DC4430 G is a white pigmented high viscosity polyether ether ketone (PEEK) resin that is especially designed for removable and fixed dentures, crowns and bridges.
VESTAKEEP® DC4430 G contains 6% Barium sulphate to render it x-ray opaque. Biocompatibility of VESTAKEEP® Dental
For VESTAKEEP® DC4430 G, biocompatibility has been tested according to ISO 10993-1 recommendations for permanent mucous membrane contact. The compound composition is optimised for high biocompatibility and superior mechanical, thermal and chemical resistance.
Biocompatibility test reports available for VESTAKEEP® DC4430 G
Processing of VESTAKEEP® Dental
VESTAKEEP® DC4430 G can be processed by common melt processing techniques like injection molding and extrusion.
For injection molding, we recommend a melt temperature in the 380°C to 400°C range. The mold temperature should be within 160°C to 200°C, preferably 180°C.
