KC 2400 (PIB) Polyisobutylene
Description
PIB2400 is a watery white, hydrophobic, non-toxic, low-molecular-weight polyisobutylene. It has a narrow molecular weight distribution, negligible sulfur content, chemically stable, lightfast, and medium thermal oxygenation.
Characteristic
Aqua white (transparent viscous liquid)
Odorless, non-toxic, high purity
Sticky
Hydrophobic and inert
Excellent oxidant and UV light stability
Superior shear stability
Excellent electrical insulating properties
High water resistance (very low moisture permeability)
Excellent lubricity and permanent non-drying
Cleans and decomposes, no residue
Non-staining properties (non-corrosive)
Raw material polymer properties
