These oils are used as Process Aids in rubber compounds.

• Processing aid –
  • to assist mechanical breakdown
  • reduce uncured compound viscosity
  • permit incorporation of fillers
  • reduce internal friction in mixing, calendering and extrusion
  • reduce durometer or modulus

This blog will talk just a bit about some of the different types of oils in use in the rubber industry.

Pressure-Volume-Temperature (PVT) properties of oils place them in one of the following groups:

• Paraffinic
• Napthenic
• Aromatic

Paraffinic Oils

• good thermal and oxidative stability
• good high-temperature viscosity
• used in EP elastomers
• Methane, Ethane, Propane

Naphthenic Oils

• very available and inexpensive
• yield medium viscosity
• used in Nitriles and other elastomers
• Cyclopentane, Cyclohexane

Aromatic Oils

• used in Natural Rubber and Neoprene
• Benzene, Toluene, Xylene
