材料文字说明
X-ray opaque, tooth-colored polyether ether ketone for dental applications

VESTAKEEP® DC4462 G is a tooth-colored, high viscosity polyether ether ketone (PEEK) resin that is especially designed for removable and fixed dentures, crowns and bridges.

VESTAKEEP® DC4462 G contains 15% barium sulphate to render it x-ray opaque. 

Biocompatibility
For VESTAKEEP® DC4462 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® DC4462 G


Processing
VESTAKEEP® DC4462 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.

Delivery
VESTAKEEP® DC4462 G is supplied as granules in 25 kg boxes with moisture-proof polyethylene liners.
