Lubricants based on Polybutenes
Lubricants can be mineral oils or synthetic oils.
Synthetic oils can be based on PAOs, PIBs or esters.
PIBs are used in different lubricants depending on their qualities as well as the requirements.
End User Applications
PIBs/PAOs can be mixed to create the optimum balance: VI / price. This is used in industrial oil, greases and compressor lubricants.
PIB/ester can be mixed to increase viscosity. This is used in 2-stroke lubricants, industrial oils, greases, chain lubricants.
Specific Lubricant Applications
POLYBUTTM, the brand name of KEMAT’s Polybutenes will/have/are in general:
- Depolymerise at high temperature, leaving no carbon residue or staining
- Excellent thickening ability
- Polymer shear stability
- Very wide range of viscosities
- Hydrophobic and non-corrosive
- Good lubricity
- High film strength
- High Viscosity Index
- Good dispersing qualities
- Low pour point
- Low- or non-volatility
- Clear and colourless
- Stable to UV-radiation
- Good oxidation stability
- Good flame resistance
KEMAT Polybutenes can replace Poly Alpha Olefines (PAO) in formulations to reduce the price while maintaining the lubricant properties. Polybutenes are compatible with PAO.
High molecular weight PIB will increase the VI (viscosity index) of the oil.
