  • Gloxil SF 91 A is a hybrid filler of fiber and Neuburg Siliceous Earth with subsequent modification bringing best properties in plastics where a good mix of stiffness and flexibility is required. The aqueous dispersion
  • Gloxil WW SL based on modified silica is for use in matt waterborne coatings and improves incorporation, transparency and resistance.
  • Struktosil 45 AM is modified fine talc grade for use in elastomers and coatings. Here, the barrier effect in particular can be enhanced.
