Carbon Dioxide Caster Compatibility

Chemical Overview

Molecular Formula: CO₂

Physical Properties: Carbon dioxide is a colorless, odorless gas at room temperature, with a density of 1.98 g/L at 0°C. It can form a weak acid (carbonic acid) when dissolved in water. It is non-flammable and relatively inert. (Source: PubChem)

Industrial Applications

Carbon dioxide is used in food and beverage processing (carbonation), fire suppression, and industrial cooling. Caster wheels may be exposed in dry ice handling or CO₂ storage areas.

Wheel Material Compatibility Summary

Best Suited (A/B): All listed materials (e.g., Polyolefin, Nylon, Polyurethane, metals) are highly resistant to carbon dioxide due to its inert nature.

Avoid (C/D): No materials are significantly affected; all are suitable.
