Unifoam AZ Chemical Foaming Ag

Functional blowing agent for plastics and rubbers

UNIFOAM AZ epitomizes Otsuka Chemical's organic temperature decomposition-type foaming agent, which is mainly composed of Azodicarbonamide. UNIFOAM AZ enables the foaming cell structure in plastics and rubbers to weigh less and thus offers a variety of functioning attributes, such as heat-insulation, flexibility, sound-proof, cushion elasticity, ornamentation, etc.

Advantages

  1. Superior dispersibility in plastic, rubber, etc.
  2. Decomposition temperatures suitable for plastic and rubber processing
  3. Ability to control decomposition temperature and speed
  4. Large gas volume (220-245ml/g)
  5. Low amount of contamination from degradation
  6. Low degradation over time; excellent storage stability

Applications

  • Energy absorption, elastic functionality (cushioning)
  • Sound absorption, automotive interiors
  • Mechanical functionality (elasticity, flexibility)
  • Light-weight applications
  • Decorative (wallpaper, leather)
  • Thermal (heat insulation)
