Key Properties:
  • Polymer Markets – Rapid incorporation, no filler agglomeration, excellent dispersion, semi-reinforcing filler, spacing effect, superb compression set.
  • Polishing – Excellent dispersion, adjustable abrasivity, good cut, low sedimentation, no scratching, chemical resistance.
Polishing

Classic Neuburg Siliceous Earth combines lemelar kaolinite, with corpuscaler, cryptocrystalline and amorphous silica. This entirely unique structure, has been found to promote significant performance benefits in polishes for a wide range of surfaces. The loose structure and narrow particle size distribution, enables easy incorporating in water and O/W emulsions, whilst offering excellent compatibility with Aluminium Oxide.

Elastomers

Sillitin and its value added cousins Aktisil, Aktifit, find a home in many rubber applications, imparticular iwthin rollers and printer blankets. Suitable markets also include within automotive ( car body seals, trim, and under the hood applications turbo hoses) and construction (pipe seals, window beading).
