Wheel Materials vs. Chemical Compatibility Guide
Casters and Wheels need to operate in a wide range of environments. Chemical exposure can greatly reduce the lifespan of certain materials so it's essential to pick the right wheel materials as compared to the chemical environments those wheels will be exposed to. Use our guide to see what wheels best fit your application. As always if you have any questions give us a call or contact us.

Boric Acid
B(OH)₃
Boric Acid Caster Compatibility
Chemical Overview
Molecular Formula: H₃BO₃
Physical Properties: Boric acid is a white crystalline solid or powder, odorless, with a density of 1.44 g/cm³ and a melting point of 170.9°C. It is soluble in water and mildly acidic. (Source: PubChem)
Industrial Applications
Boric acid is used in antiseptics, insecticides, and as a flame retardant. It is common in pharmaceutical, agricultural, and manufacturing settings, with caster wheels exposed during handling or spills.
Wheel Material Compatibility Summary
Best Suited (A/B): Polyolefin, Nylon, Nylon Glass Filled, and Polyurethane on Aluminum/Iron Core are highly resistant to boric acid.
Avoid (C/D): Avoid Ductile Cast Iron and V-Grooved Iron in prolonged exposure due to potential mild corrosion.
Wheel Compatibility Table
| Wheel Material | Interaction Description | Rating |
|---|---|---|
| Ductile Cast Iron | Mild corrosion possible with prolonged exposure. | C |
| Elastomer | Highly resistant; no significant effect. | A |
| Forged Steel | Mild corrosion risk; generally resistant. | B |
| Neoprene/Nylon Glass Core | Both components resist; highly stable. | A |
| Nylon | Excellent resistance; chemically stable. | A |
| Nylon Glass Filled | Highly resistant; no degradation. | A |
| Phenolic | Excellent resistance; no effect. | A |
| Polyolefin | Excellent chemical inertness. | A |
| Polyurethane on Aluminum Core | Highly resistant; aluminum unaffected. | A |
| Polyurethane on Iron Core | Polyurethane resists; iron core may corrode slightly. | B |
| Rubber | Resistant; no significant degradation. | A |
| Solid Elastomer | Highly resistant; no effect. | A |
| Thermoplastic Rubber | Resistant; minimal softening possible. | B |
| Urethane | Excellent resistance; chemically stable. | A |
| V-Grooved Iron | Mild corrosion possible; not ideal for long-term exposure. | C |
Conclusion
Boric acid is mildly acidic and generally compatible with most caster wheel materials. Polyolefin, Nylon, and Polyurethane-based wheels are ideal, while metal-based wheels like Ductile Cast Iron should be used cautiously. For further assistance, contact us at CasterTech.
