Isopropyl Alcohol Caster Compatibility

Chemical Overview

Molecular Formula: C₃H₈O

Physical Properties: Isopropyl alcohol is a colorless, flammable liquid with a strong odor. It has a density of 0.79 g/cm³, a boiling point of 82.6°C, and is miscible with water. It is a mild solvent. (Source: PubChem)

Industrial Applications

Isopropyl alcohol is used as a solvent, disinfectant, and in electronics cleaning. Caster wheels may be exposed in medical facilities, laboratories, or manufacturing.

Wheel Material Compatibility Summary

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

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