The alumina trihydrate production is based on Bayer process, where the raw material is bauxite. Alumina trihydrate (ATH) is produced in different grades: wet, dried, ground and finely precipitated one.
Aluminum hydroxide flame retardants (white powder) for processing temperatures up to about 160° C, for wire and cable, electronic and electrical components based on thermoset resins, building materials, mass transportation, paints and varnishes, paper and plaster with organic binder.
Ground and finely precipitated hydrates are mainly used as flame retardant filler materials in the production of:
– cable insulation
– cross-linked elastomers
– PVC/PE/PP Cable Compound
– polyester resins
– epoxy resins
– thermoplastics
– polyurethanes
– paper coating
– cellular glass
– carpet latex
– PVC/NBR Foam
– Industrial Conveyor Belt
