Carbon Disulfide Caster Compatibility

Chemical Overview

Molecular Formula: CS₂

Physical Properties: Carbon disulfide is a colorless, volatile liquid with a foul odor. It has a density of 1.26 g/cm³, a boiling point of 46.3°C, and is slightly soluble in water. It is highly flammable and toxic. (Source: PubChem)

Industrial Applications

Carbon disulfide is used in rayon production, as a solvent, and in chemical synthesis. Caster wheels may be exposed in chemical plants or during transport of CS₂-containing materials.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin, Nylon Glass Filled, and Ductile Cast Iron are highly resistant to carbon disulfide.

Avoid (C/D): Avoid Rubber, Thermoplastic Rubber, and Neoprene/Nylon Glass Core due to swelling or dissolution.

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 dissolves; nylon core resists but overall poor.	D
Nylon	Good resistance; slight solvent 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	Moderate resistance; some softening possible.	C
Polyurethane on Iron Core	Polyurethane may soften; iron core unaffected.	C
Rubber	Swelling and dissolution; 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

Carbon disulfide is a strong solvent, and Polyolefin, Nylon Glass Filled, and metal-based wheels like Ductile Cast Iron are ideal. Avoid Rubber and Thermoplastic Rubber due to severe degradation. For more details, contact us at CasterTech.
