What are Polybutenes?

Typical Properties

Polybutenes are a group of synthetic clear liquid polymers of butenes, obtained by selective polymerisation of the isobutylene contained in the butene-butane stream.

The main characcteristics are the broad range of viscosities (from 5 Cst @ 37.8C to 14,000 Cst @ 100C).  This reflects the variation on molecular weights which range from 250 to around 4500.

The main properties of KEMAT polybutenes are:

• Non toxic
• Permanently tacky
• UV stable
• Non drying
• Corrosion preventative
• High dielectric properties
• Thermal stability
• Soluble in mineral oil
• Burns without residue
• Tasteless
• Ordourless
