Indopol® Polybutene Characteristics
Indopol polybutenes have many useful properties. For instance, they are:
- Permanently non-drying
- Colorless (water white) and non-staining
- Soluble in a wide range of organic solvents
- Compatible with a wide range of organic materials
- Completely hydrophobic
- Tacky
- Emulsifiable
- Excellent electrical insulators
- Good lubricants
- Non-corrosive
- Practically non-toxic and non-phytotoxic
- Stable to light and air (i.e. oxidatively stable) under ambient conditions
- Reactive by virtue of their olefinic end-group
- Very low moisture transmission rates
- Low to negligible evaporation loss at ambient temperature
- High Viscosity Indices
- Low Pour Points
- Complete depolymerization at elevated temperature leaving no residues
Physical Properties of Indopol Polybutenes
The physical properties of all the Indopol and Panalane® grades of polybutene are summarized in Table 1.
For non-specification properties, the values quoted were obtained from samples of production materials, and are provided for guidance only.
