Polybutene Chemical Properties:
Melting point: 104 °C
Density: 0.91 g/mL at 25 °C(lit.)
Form: pellets
Odor: Data not available.
Stability: Stable. Incompatible with strong oxidizing agents.
Chemical Properties: Polybutene is generally water-white, reaching less than 50 on APHA color scale. (typically less than 10) The product remains very stable after being prolonged exposure to UV light. Polybutene is more stable than conventional mineral oil with same APHA color.
Polybutene is a non-polar hydrocarbon polymer hence it has high solubility in aliphatic, aromatic and chlorinated solvents. It is compatible with a wide variety of organic materials, for instance, synthetic hydrocarboon polymers including wax, rosin, asphalt and gum.
Polybutene is safe to use, because it is non-toxic. Polybutene is allowed by the FDA for a wide variety of applications as components of articles.
Uses: polybutene is a binder and viscosity-increasing agent used more in makeup than skin care preparations. Polybutene is a polymer of one or more butylenes obtained from petroleum oils.
Application: Fuel and lubricant additives – Fuel dispersants, lubricant dispersants
Adhesives
Caulk and sealants
Gum base
Wrap film
Lubricants – Two-stroke engine oil, lubricant for rolling wire drawing, compressor oil and viscosity index improvers (VIIs)
Electrical insulation
Others – Asphalt modifier, resin plasticiser, rubber modifier and dispersing agents
