Inorganic Foaming Agents Inorganic blowing agent for plastic and rubber

Inorganic foaming agents made from inorganic carbonate and sodium bicarbonate.

Inorganic foaming agents improve the efficiency of the foaming process through endothermic reactions. This type of reaction enhances the quality of the foamed product and avoids issues seen in organic foaming agents such as discoloration and unpleasant smells.

Advantages

  1. Whiteness reduces discoloration in foamed material
  2. Reduced die contamination and metal corrosion compared to organic agents
  3. Reduced molding time through endothermic decomposition

Applications

  • Construction materials, furniture parts
  • Rubber roll
  • Automotive interior and exterior parts
  • Consumer electronic components
