MICROSPAR® for highest demands


MICROSPAR® is the tradename for our High Performance Fillers based on micro fine feldspar flours. Their key parameters are good chemical resistance, purity and high transparency.

MICROSPAR® 1351 has been especially developed for dental applications and is available with and without surface-treatement.

Through the use of MICROSPAR® 1351 the 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 behavior are excellent.

Optimized polyolefin films by using MICROSPAR®1379

  • For packaging films antiblocking additives with good optical properties have been developed.
  • In agricultural films UV transmission and IR transmittance are also essential parameters.
  • An optimized barrier effect in terms of gas permeability plays a big role in composite films.

If films are used to package fruit, vegetables, fish, sausage or cheese, anti-blocking agents are used more or less as a 'spacer' to more easily separate the sides of the film from one another. The effectiveness of the anti-blocking additive is mainly dependent on the properties of the mineral used and the correct grain size. Visual requirements, such as transparency, gloss and opacity, are often added to the mechanical properties. After all, consumers would like to see what they are buying and they therefore gladly reach for transparent plastic packaging. We offer the suitable filler for every film application.
