Oleic Acid Caster Compatibility

Chemical Overview

Molecular Formula: C₁₈H₃₄O₂

Physical Properties: Oleic acid is a colorless to pale yellow liquid with a mild odor. It has a density of 0.89 g/cm³, a boiling point of 360°C, and is insoluble in water. It is a non-polar fatty acid. (Source: PubChem)

Industrial Applications

Oleic acid is used in cosmetics, lubricants, and food processing. Caster wheels may be exposed in manufacturing or food production facilities.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin, Nylon Glass Filled, and Ductile Cast Iron are highly resistant to oleic acid.

Avoid (C/D): Avoid Rubber and Thermoplastic Rubber due to potential swelling or softening.
