Polybutene 2400

Model: PB 2400DowSyn® PB2400 is the low molecular polyisobutylene with water-white, hydrophobic and non-toxic. It has narrow molecular weight distribution and negligible sulfur content with chemically stable and resistant to oxidation by both light and moderate heat.

Characteristic

  • Water-White Color (transparent viscous liquid)
  • Non Odor & Non-Toxic & High Purity
  • Tacky
  • Hydrophobic & Inertness
  • Excellent Stability of Oxidant and UV Light
  • Superior Shear Stability
  • Excellent Electrical Insulating Properties
  • Great Water Repellency (very low moisture transmission rates)
  • Outstanding Lubricity & Permanently Non-Drying
  • Clean Decomposition & No Residue
  • Non-Staining Characteristics (non-corrosive)
