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.

Fluoboric Acid
HBF₄
Fluoboric Acid Caster Compatibility
Chemical Overview
Molecular Formula: HBF₄
Physical Properties: Fluoboric acid is a colorless liquid in aqueous solution, typically 48-50% concentration. It has a density of ~1.4 g/cm³ at 20°C and is highly soluble in water. It is a strong acid and corrosive. (Source: PubChem)
Industrial Applications
Fluoboric acid is used in:
- Electroplating: In tin and lead plating processes.
- Metal Cleaning: For surface preparation and pickling.
- Catalysis: In organic synthesis and polymerization.
- Exposure Scenarios: Spills in plating facilities or chemical labs may contact caster wheels.
Wheel Material Compatibility Summary
Best Suited Materials (A/B Ratings): Polyolefin (A) resists acid corrosion; Phenolic (B) offers moderate resistance.
Materials to Avoid (C/D Ratings): Avoid metals (Ductile Cast Iron, Forged Steel) and elastomers (Rubber, Urethane) due to corrosion or degradation.
Wheel Compatibility Table
| Wheel Material | Interaction Description | Rating |
|---|---|---|
| Ductile Cast Iron | Corrodes rapidly in acidic conditions. | D |
| Elastomer | Degrades under strong acids. | D |
| Forged Steel | Prone to corrosion from acids. | D |
| Neoprene/Nylon Glass Core | Neoprene degrades; nylon core has limited resistance. | C |
| Nylon | Moderate resistance; degrades over time. | C |
| Nylon Glass Filled | Slightly better than nylon; still vulnerable. | C |
| Phenolic | Resistant to acids; moderate performance. | B |
| Polyolefin | Excellent acid resistance; unaffected. | A |
| Polyurethane on Aluminum Core | Polyurethane degrades; aluminum corrodes slightly. | D |
| Polyurethane on Iron Core | Polyurethane degrades; iron corrodes. | D |
| Rubber | Rapid degradation from acid exposure. | D |
| Solid Elastomer | Degrades in acidic conditions. | D |
| Thermoplastic Rubber | Poor resistance to acids; degrades. | D |
| Urethane | Degrades under acid exposure. | D |
| V-Grooved Iron | Corrodes rapidly in acid. | D |
Conclusion
Fluoboric acid’s corrosive nature makes Polyolefin wheels (A rating) the best choice. Avoid metals (Ductile Cast Iron, Forged Steel) and elastomers (Rubber, Urethane) due to corrosion and degradation. For help, contact CasterTech.
