Anorganic reinforcing fillers for industrial applications are an important backbone in modern composite materials. We offer various staple fibres and centrifuged microfibers for different applications.

A staple fibre is produced using an endless sheet (roving) and then cut into the necessary fibre lengths. The roving is spun from the liquefied material. Each of these rovings is made up of several dozen filaments (single fibres), which are then cut into the desired length after cooling.

Centrifuged glass microfibers are sprayed through an extruder head, thus obtaining a clearly finer distribution than conventional fibres. For this reason, the appearance is rather more like wadding than fibre.

HOP-MIX

HOP-MIX 2303-A0 is one of the centrifuged glass microfibers. These fibres draw on a sophisticated process, which liquefies a glass and then sprays it in very delicate fibres. These fibres then exist as casts and can be embedded into a matrix. The chemistry of the glass and the small fibre diameter help to create a transparent end product, even in the highest applied concentrations. The systematic distribution of the very fine fibres offers higher resistances over the entire structure. It is also possible to use it as a cost-effective replacement for pyrogenic silica, as HOP-MIX also has a high absorption capacity with a large surface area.

HOP-BASALT

Basalt fibers consist of naturally occurring rock. The production process is adapted to the characteristics of this very pure raw material. For the chopped fibers, an endless strip (roving) is first produced from the liquid melt of the raw material and then cut into the required fiber length. Each of these rovings consists of several filaments (single fibers), which are standardly coated with a silane finishing.

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.

Cenospheres THERMO-SPHERES^®

THERMO-SPHERES^®, Grey

Description

THERMO-SPHERES^® G are high quality hollow ceramic microspheres < 150 μm, which are characterised by a high degree of fineness as well as a particularly high mechanical strength. The products are pre-dried. Because of the high fineness, they display good grinding properties and are, therefore, highly suitable as insulation and lightweight filling materials.

Application

THERMO-SPHERES^® G are used in applications which require the use of particularly small hollow microspheres or make high demands on surface finish. This includes, apart from the use in paints and coatings, composite materials, special casting compounds and putties, adhesives and sealants.

Description

THERMO-SPHERES^® W are white, high quality hollow ceramic microspheres < 150 μm, which are characterised by a high degree of fineness as well as a particularly high mechanical strength. The products are pre-dried and usable for foundry industry. The white colour allows their use in aesthetically demanding applications such as decorative plasters and wall paints.

Application

THERMO-SPHERES^® W are used in bright applications which require the use of the smallest possible microspheres or make high demands on surface quality. This includes applications in addition to the use in paints and coatings, surfaces as well as special casting compounds and adhesives where a high whiteness is advantageous.

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.

LUVOTIX^® - Organic rheology additives for solvent-based and solvent-free systems

LUVOTIX^® rheology additives are fine, micronized waxes that are mainly made from renewable raw materials. The powders are based on castor oil derivatives, fatty acid amides and polyolefins.              
Depending on the polarity of the system, the products are incorporated directly in powdered form in a time and temperature-controlled dispersing process. In addition to the standard types that have proven themselves and have been tested for many years, rheology additives that are particularly easy to activate are available. These develop their full effectiveness even at low temperatures after shearing.

LUVOGEL^® - Inorganic rheology additives for solvent-based and water-based systems

Naturally occurring and organically modified phyllosilicates from the LUVOGEL^® series are used in water-based and solvent-based systems for rheology control. The powdered additives are incorporated directly at the beginning of the dispersing process or in form of pre-gels. Polar chemical activators are sometimes added to increase gel formation in solvent-based systems. Easily dispersible and self-activating LUVOGEL^® additives enable fast and successful activation processes without the necessity to control the temperature.

WOLLATROP^® - Inorganic rheology additives for water-based systems

WOLLATROP^® are hydrated and inverted ribbon silicates that are used as inorganic thickeners in water-based systems. The additives are particularly easy to incorporate into formulations thanks to their filamentous and flexible structure. Unlike classic phyllosilicates, WOLLATROP^® products develop a stable structure immediately after incorporation, which leads to increased viscosity, especially in the low shear rate range. WOLLATROP^® products are characterized by a high tolerance to changes in ionic strength and pH fluctuations.
