Short overview about applications and corresponding effects of precipitated and fumed silica as well as metal oxides in the plastics industry.
This flyer provides you with some basic information about the usage of SIPERNAT® specialtty silica and AEROSIL® fumed silica as free flow and anti-caking agents for sticky Polymer powders and granules.
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.
SIPERNAT® 820 A improves thermal barrier properties of greenhouse film (PE)
Powdered ingredients are used increasingly in many industries. A good flowability is the prerequisite for handling powders properly, discharching them easily out of a silo and dosing them exactly. However, many powders are highly cohesive and the proper processing thereforce is a challenge. Additionally many powders tend to cake on storage or while being transported due to climate conditions pressure.
Performance 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. With numerous hydrophilic and hydrophobic AEROSIL® Fumed Silica as well as Sipernat® Precipitated Silica, Evonik offers the best choice of problem solvers worldwide.
SIPERNAT® Specialty Silica and AEROSIL® Fumed Silica are referred to as a “carrier” when they are used to hold and absorb liquids in the production of a dry, free-flowing powder. Any size silica product can be used as a carrier; making either coarse or fine absorbates.
