Nabaltec APYRAL® 22 Al(OH)3
Categories: Ceramic; Oxide; Aluminum Oxide; Other Engineering Material; Additive/Filler for Polymer

Material Notes: APYRAL ® from Nabaltec is an environmentally friendly halogen free product which is used as a flame retardant filler in a wide variety of rubber and polymeric materials. During thermal decomposition APYRAL ® does not generate toxic or corrosive gases. In addition, there is a distinct reduction in smoke density. APYRAL ® is effective in the crucial phase of the burning process before the outbreak of a fully developed fire.

APYRAL ® can be used as a flame retardant filler in

  • Thermosets
  • Elastomers
  • Thermoplastics
  • Cable Compounds
  • Technical Rubber Compounds
  • Pressed and cast Plastic Parts
  • Thermal Insulation Foams
  • Glass-fiber reinforced plastics

Key Words: Aluminum Hydroxide, Al(OH)3
