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.

Aniline
C₆H₅NH₂
Aniline Caster Compatibility
Chemical Overview
Molecular Formula: C₆H₇N
Physical Properties: Aniline is a colorless to brown oily liquid with a musty odor. It has a density of 1.02 g/cm³, a boiling point of 184.1°C, and is slightly soluble in water. It is toxic and reactive with some materials. (Source: PubChem)
Industrial Applications
Aniline is used in dye manufacturing, pharmaceuticals, and rubber processing. Caster wheels may be exposed in chemical plants or during transport of aniline-containing materials.
Wheel Material Compatibility Summary
Best Suited (A/B): Polyolefin and Nylon Glass Filled are highly resistant to aniline. Polyurethane on Aluminum Core is also suitable.
Avoid (C/D): Avoid Rubber, Thermoplastic Rubber, and Neoprene/Nylon Glass Core due to swelling or degradation.
Wheel Compatibility Table
| Wheel Material | Interaction Description | Rating |
|---|---|---|
| Ductile Cast Iron | Resistant; minimal interaction. | A |
| Elastomer | Swelling and softening; unsuitable. | D |
| Forged Steel | Resistant; no significant degradation. | A |
| Neoprene/Nylon Glass Core | Neoprene degrades; nylon core resists but overall poor. | D |
| Nylon | Good resistance; slight absorption. | B |
| Nylon Glass Filled | Excellent resistance; highly stable. | A |
| Phenolic | Moderate resistance; some softening. | C |
| Polyolefin | Excellent chemical inertness. | A |
| Polyurethane on Aluminum Core | Good resistance; aluminum unaffected. | A |
| Polyurethane on Iron Core | Polyurethane resists; iron core unaffected. | A |
| Rubber | Swelling and degradation; unsuitable. | D |
| Solid Elastomer | Swelling; poor performance. | D |
| Thermoplastic Rubber | Significant swelling; rapid degradation. | D |
| Urethane | Moderate resistance; some softening. | C |
| V-Grooved Iron | Resistant; no significant interaction. | A |
Conclusion
Aniline is a reactive organic compound, and Polyolefin, Nylon Glass Filled, and Polyurethane-based wheels are the best choices. Avoid Rubber and Thermoplastic Rubber due to severe degradation. For further guidance, contact us at CasterTech.
