Polybutene 1300
Model: PB 1300DowSyn® PB1300 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)
