Feldspar Flours

A picture of a model plastic tooth

Product Overview

MICROSPAR® products are based on micro fine feldspar flours. They have been especially developed for uv-cured dental composites and are available with and without surface-treatement. Key parameters are good chemical resistance, purity and high transparency. An almost invisible repair of teeth is possible. In addition, the production of artificial teeth is possible with this special filler. MICROSPAR® 1351 increases the mechanical strength and radio-opacity can be achieved (Yb-F). The workability of the composite and the polishing behaviour are excellent.

Certainly, these products can be used in other UV-cured composites as well.
