Silica – a manifold of solutions for plastics
AEROSIL® fumed silica is invented to improve the manufacturing, quality and performance of thermoplastics, polymer compounds, composites and Thermpolastic Elastomers (TPE). Both, hydrophilic and hydrophobic types of AEROSIL® fumed silica are used as additive for:
Antiblocking agent in polymer films
Matting of plastics
IR absorbtion in greenhouse film
Nucleation of foam
Flame retardant synergist
Besides our fumed silica we are offering various precipitated silica-tpyes "SIPERNAT®" which can also be used to reach a.m. effects. Whether a fumed or a precipitated silica should be used depends on the individual parameters like: polymer, targeted effect and performance level, type of machinery and equipment, dosing level, etc. Further information you will find in our flyer and on our SIPERNAT® homepage.

Recommended mixing procedures for powders and granulates Specialty Silica have found their way with numerous applications into many branches of industry. This also applies to their use as carrier for liquid or pasty substances as well as the application as flow aid for powdered or granular products. Due to their fineness and low bulk density mixing with other ingredients is somehow sophisticated. This Technical Information gives some recommendation on suitable mixing equipment and how to use it, when Specialty Silica are concerned.
