Chlorine Wet Caster Compatibility

Chemical Overview

Molecular Formula: Cl₂ (in aqueous solution)

Physical Properties: Wet chlorine refers to chlorine gas in the presence of moisture, forming hypochlorous acid (HOCl) or hydrochloric acid (HCl). It is highly corrosive, especially to metals, and reactive. (Source: PubChem)

Industrial Applications

Wet chlorine is encountered in water treatment, bleaching, and chemical manufacturing. Caster wheels may be exposed in wet environments like pools or processing plants.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin and Nylon Glass Filled are highly resistant to wet chlorine. Polyurethane on Aluminum Core is also suitable.

Avoid (C/D): Avoid Ductile Cast Iron, Forged Steel, V-Grooved Iron, and Rubber due to severe corrosion or degradation.

Wheel Compatibility Table

Wheel Material	Interaction Description	Rating
Ductile Cast Iron	Severe corrosion; rapid degradation.	D
Elastomer	Moderate degradation; limited suitability.	C
Forged Steel	Severe corrosion; unsuitable.	D
Neoprene/Nylon Glass Core	Neoprene degrades; nylon core resists but overall poor.	C
Nylon	Good resistance; slight degradation possible.	B
Nylon Glass Filled	Excellent resistance; highly stable.	A
Phenolic	Moderate resistance; some degradation.	C
Polyolefin	Excellent chemical inertness.	A
Polyurethane on Aluminum Core	Good resistance; aluminum unaffected.	A
Polyurethane on Iron Core	Polyurethane resists; iron core corrodes.	C
Rubber	Severe degradation; unsuitable.	D
Solid Elastomer	Moderate degradation; poor performance.	C
Thermoplastic Rubber	Degrades; unsuitable.	D
Urethane	Moderate resistance; some degradation.	C
V-Grooved Iron	Severe corrosion; unsuitable.	D

Conclusion

Wet chlorine is highly corrosive, and Polyolefin, Nylon Glass Filled, and Polyurethane on Aluminum Core are the best choices. Avoid metal-based wheels and Rubber due to severe corrosion and degradation. For further guidance, contact us at CasterTech.
