Freon 11 Caster Compatibility

Chemical Overview

Molecular Formula: CCl₃F

Physical Properties: Freon 11 (trichlorofluoromethane) is a colorless liquid or gas with a slight odor. It has a density of 1.49 g/cm³, a boiling point of 23.8°C, and is insoluble in water. It is non-flammable but a mild solvent. (Source: PubChem)

Industrial Applications

Freon 11 is used as a refrigerant and solvent, though its use is declining due to environmental concerns. Caster wheels may be exposed in refrigeration systems or chemical storage areas.

Wheel Material Compatibility Summary

Best Suited (A/B): Polyolefin, Nylon Glass Filled, and Ductile Cast Iron are highly resistant to Freon 11.

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

Wheel Compatibility Table

Wheel Material	Interaction Description	Rating
Ductile Cast Iron	Resistant; minimal interaction.	A
Elastomer	Moderate swelling; limited suitability.	C
Forged Steel	Resistant; no significant degradation.	A
Neoprene/Nylon Glass Core	Neoprene may swell; nylon core resists but overall poor.	C
Nylon	Good resistance; slight solvent absorption.	B
Nylon Glass Filled	Excellent resistance; highly stable.	A
Phenolic	Good resistance; minimal effect.	B
Polyolefin	Excellent chemical inertness.	A
Polyurethane on Aluminum Core	Good resistance; aluminum unaffected.	B
Polyurethane on Iron Core	Polyurethane resists; iron core unaffected.	B
Rubber	Swelling; unsuitable for prolonged exposure.	C
Solid Elastomer	Moderate swelling; limited suitability.	C
Thermoplastic Rubber	Swelling; poor performance.	C
Urethane	Good resistance; slight softening possible.	B
V-Grooved Iron	Resistant; no significant interaction.	A

Conclusion

Freon 11 is a mild solvent, and Polyolefin, Nylon Glass Filled, and metal-based wheels like Ductile Cast Iron are ideal. Avoid Rubber and Thermoplastic Rubber due to potential swelling. For more details, contact us at CasterTech.
