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.

Acetic Acid (10–50%)
CH₃COOH
Acetic Acid 10-50% Caster Compatibility
Chemical Overview
Molecular Formula: C₂H₄O₂
Physical Properties: Acetic acid (10-50% concentration) is a colorless liquid with a pungent, vinegar-like odor. It has a density of approximately 1.01-1.07 g/cm³, a boiling point of 100-118°C, and is miscible with water. It is a weak organic acid, corrosive to some materials. (Source: PubChem)
Industrial Applications
Acetic acid (10-50%) is used in food processing (vinegar production), chemical manufacturing, and as a cleaning agent. It is common in industries like textiles, pharmaceuticals, and plastics. Exposure scenarios include spills in production areas or cleaning operations, potentially affecting caster wheels on carts or equipment.
Wheel Material Compatibility Summary
Best Suited (A/B): Polyolefin, Polyurethane on Aluminum Core, and Nylon Glass Filled offer excellent to good resistance to acetic acid (10-50%). These materials are recommended for environments with regular exposure.
Avoid (C/D): Avoid Rubber, Neoprene/Nylon Glass Core, and Ductile Cast Iron, as they are prone to swelling, degradation, or corrosion when exposed to acetic acid.
Wheel Compatibility Table
| Wheel Material | Interaction Description | Rating |
|---|---|---|
| Ductile Cast Iron | Corrodes due to acidic nature; pitting possible. | D |
| Elastomer | Moderate swelling; reduced lifespan. | C |
| Forged Steel | Corrosion risk; protective coatings may help. | C |
| Neoprene/Nylon Glass Core | Neoprene swells; nylon core may resist but overall poor. | D |
| Nylon | Good resistance; minimal degradation. | B |
| Nylon Glass Filled | Excellent resistance; highly stable. | A |
| Phenolic | Good resistance; slight absorption possible. | B |
| Polyolefin | Excellent chemical inertness; no degradation. | A |
| Polyurethane on Aluminum Core | Good resistance; aluminum core unaffected. | A |
| Polyurethane on Iron Core | Polyurethane resists; iron core may corrode if exposed. | B |
| Rubber | Swells and degrades rapidly. | D |
| Solid Elastomer | Moderate swelling; limited suitability. | C |
| Thermoplastic Rubber | Swells; poor long-term performance. | D |
| Urethane | Good resistance; slight softening possible. | B |
| V-Grooved Iron | Corrodes; unsuitable for acidic environments. | D |
Conclusion
Acetic acid (10-50%) is moderately aggressive to caster wheel materials. Polyolefin, Polyurethane on Aluminum Core, and Nylon Glass Filled are the best choices for durability, while Rubber and metal-based wheels like Ductile Cast Iron should be avoided due to degradation or corrosion.
