Precipitated aluminium hydroxide MITALOX®-PH 2
* We are able to control the size of products and adapt it to the needs of the client
Physical and Chemical Characteristics
Compared with the milled aluminum trihydrate, the precipitated aluminum hydroxide has a number of advantages:
─ average particle size d50=1.5-2.5 µm
─ chemical purity (low impurity content),
─ narrow particle size distribution,
─ smooth surface and round shape of the particles (sphericity coefficient is not less than 0.9), which facilitates the introduction of hydroxide into the compounds;
─ improved thermal stability to increase extrusion speed and produce complex compounds;
─ low dust emission of powder.
The use of aluminum hydroxide is advisable as a flame retardant in polymer compositions, mainly in:
1) Halogen Free Flame Retardant (HFFR);
2) Silane-crosslinkable PE compounds;
3) thermoplastic, particularly plasticized PVC compounds;
4) rubber compounds.
At the request of the customer, it is possible to modify aluminum hydroxide with various coupling agent. Coating of powder particles with organic coupling agent reduces the viscosity of polymer compounds. In addition, surface treatment improves the mechanical and electrical insulation properties of the compounds.
Industrial production line of the precipitated aluminium hydroxide is in the design stage. Currently, we are ready to provide you with test samples produced at our pilot production site.
