WOLLATROP® Manufacturer: Lehmann&Voss&Co.

Inorganic thickeners of the WOLLATROP® series are based on inosilicate technology. This technology has a similar effect to the well-known phyllosilicate thickeners, but behaves very differently in the high shear range. Due to the thread-like structure, alignment in the printing direction is possible, which allows easier processing than comparable phyllosilicates. 

The WOLLATROP® series permits the use of inorganic thickeners in aqueous systems. Their valued properties in the high shear range as well as their strong thixotropic effect support an excellent product. By combining different types it is possible to create a rheology profile tailored to the needs of the user. With different processes it is possible to significantly influence the thickening effect.

Functional Fillers

Hollow ceramic microspheres are extremely resistant hollow spheres, which are formed under the exposure of extreme heat. Temperatures over the relevant melting points are required to achieve a ceramic melting. Drops with a hollow are formed as a result of the subsequent rapid cooling process. The OMEGA-SPHERES® formed in this way are refined and fractionated in subsequent processes, thus being a high-quality raw material in your formulations.

The spheres we provide are produced at various production sites for global availability. Globally produced standard types are manufactured in the Ukraine and Germany. Special types are produced in Germany. There are further suppliers in Europe and throughout the world.

Closed cell perlite based hollow microspheres TRI-SPHERES®

Description

TRI-SPHERES® are hollow multi-cellular microspheres with a popcorn structure on a silicate basis. TRI-SPHERES® serve as functional lightweight fillers. Their heat resistance is up to 1,500 °C. Their compressive strength ends at 2,900 PSI / 20 Mpa. With a view to any shear forces occurring during the incorporation, their multi-cellular structure avoids that all spheres are destroyed at high forces. TRI-SPHERES® are marked by a clear bright colour.

Application

TRI-SPHERES® can be used as lightweight fillers in many different applications such as paints and coatings, foams in composites as well as in hydraulic-setting cement for construction chemistry (TRI-SPHERES® 120 XL). With a view to the optimisation of acoustic and thermal properties, TRI-SPHERES® 300 and 400 are recommended. In particular the fine TRI-SPHERES® 45XS Ultra achieves good results in partial weight reduction of PP polymer for injection mouldingwhen adding 10 – 15 % as an additive for the last step.

OMEGA-SIL®

Description

OMEGA-SIL® are solid aluminium silicate spheres which have a very high compressive strength. The OMEGA-SIL® SPECIAL* product range consists of aluminium silicates that are processed in an additional processing step sifted. This particularly sharp separation of the top cut results in aesthetic applications to smoother surfaces.

Application

Due to the lower specific surface the use of OMEGA-SIL® in paints and coatings allows a higher degree of filling. OMEGA- SIL® shows in cementitious systems pozzolanic reactivity. The inside microcrystalline structure results in a significant increase of mechanical strength.
