CELOGEN® Chemical Foaming Agents

CelChem CELOGEN® foaming or blowing agents offer chemical technology to expand rubber or plastics. CelChem is a global distributor of chemical foaming agents and has been an industry leader for decades. CELOGEN® blowing agents allow thermoplastics and elastomer manufacturers to obtain multiple product densities. These nitrogen-based grades provide nonstaining, odorless, and dispersible benefits. Furthermore, compounders, extruders, rotational molders, injection molders, and compression molders can find many uses for their products by integrating CELOGEN® foaming agents. 

What Are Foaming Agents?

CELOGEN® foaming agent additives help produce a cellular structure in various polymers that partake in a hardening phase. Blowing agents are added during the liquid stage, and the polymer's cellular structure loses density while increasing stiffness and thermal insulation properties. The terms blowing agents and foaming agents can be used interchangeably as they both entail a chemical foaming process. CELOGEN® foaming agents are exothermic and generate heat during decomposition while emitting large amounts of gas volume producing various desired density levels. 

Why Use CELOGEN® Foaming Agents?

  • Improve thermal and audible insulation
  • Scalable and reduces costs
  • Produce closed-cell structures
  • Lower processing temperatures
  • Faster cycle times
  • Reduce machine energy
  • Uniformity in particle size and decomposition temperature
  • Reduce overall weight
  • Improve printing on flat surfaces
  • Easy drop-in solution
