Methyl Alcohol Caster Compatibility

Chemical Overview

Molecular Formula: CH₃OH

Physical Properties: Methyl alcohol (methanol) is a colorless, flammable liquid with a mild odor. It has a density of 0.79 g/cm³, a boiling point of 64.7°C, and is miscible with water. It is a polar solvent. (Source: PubChem)

Industrial Applications

Methyl alcohol is used as a solvent, fuel, and in chemical synthesis. Caster wheels may be exposed in laboratories, manufacturing, or fuel storage areas.

Wheel Material Compatibility Summary

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

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