Diethylene Glycol Caster Compatibility

Chemical Overview

Molecular Formula: C₄H₁₀O₃

Physical Properties: Diethylene glycol is a colorless, odorless liquid with a density of 1.12 g/cm³ and a boiling point of 245°C. It is miscible with water and non-corrosive. (Source: PubChem)

Industrial Applications

Diethylene glycol is used in antifreeze, plastics, and as a solvent. Caster wheels may be exposed in manufacturing or during handling of glycol-based products.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin, Nylon, Nylon Glass Filled, and Polyurethane-based wheels are highly resistant to diethylene glycol.

Avoid (C/D): Avoid Ductile Cast Iron and V-Grooved Iron in prolonged exposure due to potential mild corrosion.

Wheel Compatibility Table

Wheel Material	Interaction Description	Rating
Ductile Cast Iron	Mild corrosion possible with prolonged exposure.	C
Elastomer	Highly resistant; no significant effect.	A
Forged Steel	Mild corrosion risk; generally resistant.	B
Neoprene/Nylon Glass Core	Both components resist; highly stable.	A
Nylon	Excellent resistance; chemically stable.	A
Nylon Glass Filled	Highly resistant; no degradation.	A
Phenolic	Excellent resistance; no effect.	A
Polyolefin	Excellent chemical inertness.	A
Polyurethane on Aluminum Core	Highly resistant; aluminum unaffected.	A
Polyurethane on Iron Core	Polyurethane resists; iron core may corrode slightly.	B
Rubber	Resistant; no significant degradation.	A
Solid Elastomer	Highly resistant; no effect.	A
Thermoplastic Rubber	Resistant; minimal softening possible.	B
Urethane	Excellent resistance; chemically stable.	A
V-Grooved Iron	Mild corrosion possible; not ideal for long-term exposure.	C

Conclusion

Diethylene glycol is non-corrosive and compatible with most caster wheel materials. Polyolefin, Nylon, and Polyurethane-based wheels are ideal, while metal-based wheels like Ductile Cast Iron should be used cautiously. For more information, contact us at CasterTech.
