1,1′-(1,1,2,2-Tetramethyl-1,2-ethanediyl)bisbenzene
CAS No.: 1889-67-4
Molecular Formula: C18H22
Molecular Weight: 238.37
Application:
Dicumene – Flame Retardant Synergist in fire-retardant polystyrene, PP, PE, PS, ABS, etc, saving brominated flame retardants by 30% to 50%. Especially for EPS and XPS fire-retardant is made by using halogen-containing additives such as hexabromocyclododecane (HBCD) and the ST-130 flame retardant.
Dicumene is commonly used as a synergistic coagent to reduce the amount of HBCD required. Dicumene is well suited to this application as it has sufficient thermal stability at the temperatures used in suspension polymerization. Adding KEMYL 97 to styrene monomer immediately before the onset of polymerization will not affect the polymerization process.
Dicumene also can be used as a catalyst for polymer Crosslinking or Grafting for Polymers such as PP, and PS………
