Aluminium flitter

These coarse, lamellar particles are produced by grinding or stamping aluminium foils.

In addition to pyrotechnics (to produce certain effects), application areas are primarily found in the chemical industry.

Aquapor

The Aquapor® series includes dust-free aluminium paste preparations consisting of aluminium powder, water and stabilizing additives.

These pastes in a soluble matrix are characterized by excellent dispersion and, at the same time, a high degree of stability in the paste suspension.

Calcium carbonate mixtures

For applications that require a medium for generating porosity in plasters and mortars, mixtures of aerated concrete aluminium powders and calcium carbonate are recommended to inhibit the ability of the powder mixture to ignite.

DEG

In contrast to the Aquapor® water pastes, the DEG pastes contain diethylene glycol (DEG) as a pasting substance.

These pastes are recommended for use wherever high storage temperatures and long transportation routes require excellent storage stability.

Foil grit

In contrast to "spray grit", which is produced by atomizing molten metal, the granules known as "foil grit" are produced by recycling household and packaging foils.

0/106 approx. 96 0 - 106

630/1000 approx. 96 630 - 1000

Aerated concrete aluminium powders

Produced from aluminium grit using wet or dry grinding in a ball mill.

By varying the production process, particle size distribution and, if required, post-treatment of the aluminium particles, performance properties such as reaction start time, reaction speed, the resulting pore structure and casting stability are adapted to meet the requirements for the building material (bulk density, strength, etc.). Effective quality controls and an international technical application service are the foundation of Schlenk`s position as a market and technology leader.

Slurry aluminium powder

Lamellar aluminium powders found in safe explosives or "slurry explosives" are primarily used for "sensitizing" the explosive compounds.

Hydrophobing generates stability in the aqueous system.

Slurry aluminium powder, dust-free

These products consist of dry, lamellar aluminium powders that have been dedusted for safety reasons in a special process.

By adding small amounts of PTFE and using the appropriate procedural sequence, the aluminium powder is integrated into a matrix, similar to a spider web, and is then nearly dust-free when used in processing.
