Phosphoric Acid 10% Caster Compatibility

Chemical Overview

Molecular Formula: H₃PO₄

Physical Properties: Phosphoric acid (10% aqueous solution) is a colorless liquid with no odor. It has a density of ~1.07 g/cm³, is miscible with water, and is a weak acid. (Source: PubChem)

Industrial Applications

Phosphoric acid is used in food processing, rust removal, and fertilizer production. Caster wheels may be exposed in food production or chemical manufacturing.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin, Nylon Glass Filled, and Polyurethane on Aluminum Core are highly resistant to 10% phosphoric acid.

Avoid (C/D): Avoid Ductile Cast Iron, Forged Steel, and V-Grooved Iron due to corrosion risks.

Wheel Compatibility Table

Wheel Material	Interaction Description	Rating
