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.

Sulfuric Acid (10% )
H₂SO₄
Sulfuric Acid (10%+ Acid) Caster Compatibility
Chemical Overview
Molecular Formula: H₂SO₄
Physical Properties: Sulfuric acid (10%+ (10% or higher) is a colorless, odorless, viscous liquid with strong acidity. It has a density of ~1.07 g/cm³ (10% solution) to 1.84 g/cm³ (98% solution) at 20°C and is fully miscible with water, releasing heat. It is highly corrosive and a strong oxidizer at higher concentrations. (Source: PubChem)
Industrial Applications
Sulfuric acid (10%+) is used in:
- Fertilizer Production: In manufacturing phosphates.
- Metal Processing: For pickling and etching metals.
- Chemical Synthesis: In producing detergents and dyes.
- Exposure Scenarios: Spills in chemical or metal processing plants may contact caster wheels.
Wheel Material Compatibility Summary
Best Suited Materials (A/B Ratings): Polyolefin (A) resists acidic solutions. Phenolic (B) offers moderate resistance at lower concentrations.
Materials to Avoid (C/D Ratings): Avoid metals (Ductile Cast Iron, Forged Steel) and elastomers (Rubber, Urethane) due to corrosion or degradation, especially at higher concentrations.
Wheel Compatibility Table
| Wheel Material | Interaction Description | Rating |
|---|---|---|
| Ductile Cast Iron | Corrodes rapidly in acidic conditions. | D |
| Elastomer | Degrades in strong acids. | D |
| Forged Steel | Corrodes in sulfuric acid solutions. | D |
| Neoprene/Nylon Glass Core | Neoprene degrades; nylon resists moderately at 10%. | C |
| Nylon | Moderate resistance at 10%; degrades at higher concentrations. | C |
| Nylon Glass Filled | Similar to nylon; limited resistance. | C |
| Phenolic | Resistant to dilute acids; moderate at 10%+. | B |
| Polyolefin | Excellent resistance; unaffected by acid. | A |
| Polyurethane on Aluminum Core | Polyurethane degrades; aluminum corrodes. | D |
| Polyurethane on Iron Core | Polyurethane degrades; iron corrodes. | D |
| Rubber | Rapid degradation in acidic conditions. | D |
| Solid Elastomer | Degrades in strong acids. | D |
| Thermoplastic Rubber | Poor resistance to acids; degrades. | D |
| Urethane | Degrades under acidic exposure. | D |
| V-Grooved Iron | Corrodes rapidly in acidic conditions. | D |
Conclusion
Sulfuric acid (10%+) is highly corrosive, making Polyolefin wheels (A rating) the best choice. Avoid metals (Ductile Cast Iron, Forged Steel) and elastomers (Rubber, Urethane) due to corrosion and degradation (D ratings). For assistance, contact CasterTech.
