Phenol Caster Compatibility

Chemical Overview

Molecular Formula: C₆H₅OH

Physical Properties: Phenol is a white crystalline solid or colorless liquid with a distinct sweet, tarry odor. It has a melting point of 40.5°C, a boiling point of 181.7°C, and a density of 1.07 g/cm³ at 20°C. It is moderately soluble in water (8.3 g/100 mL) and corrosive. (Source: PubChem)

Industrial Applications

Phenol is used in:

• Plastics: In producing phenolic resins and bisphenol A.
• Disinfectants: In antiseptics and sanitizers.
• Chemical Synthesis: For dyes, pharmaceuticals, and pesticides.
• Exposure Scenarios: Spills in resin or chemical manufacturing may contact caster wheels.

Wheel Material Compatibility Summary

Best Suited Materials (A/B Ratings): Polyolefin (A) and Ductile Cast Iron (A) resist phenol’s solvent and acidic properties. Phenolic (B) is suitable despite irony of its name.

Materials to Avoid (C/D Ratings): Avoid Rubber, Thermoplastic Rubber, and Urethane (C/D) due to swelling or degradation.

Wheel Compatibility Table

Wheel Material	Interaction Description	Rating
Ductile Cast Iron	Resistant to phenol; minimal corrosion.	A
Elastomer	Swelling and degradation likely.	C
Forged Steel	Minor corrosion possible.	B
Neoprene/Nylon Glass Core	Neoprene degrades; nylon resists moderately.	C
Nylon	Moderate resistance; swelling possible.	C
Nylon Glass Filled	Slightly better than nylon; minor swelling.	C
Phenolic	Good resistance; minimal degradation.	B
Polyolefin	Excellent inertness; unaffected.	A
Polyurethane on Aluminum Core	Polyurethane degrades; aluminum resists.	C
Polyurethane on Iron Core	Polyurethane degrades; iron may corrode slightly.	C
Rubber	Significant swelling and degradation.	D
Solid Elastomer	Swelling likely; poor performance.	C
Thermoplastic Rubber	Degrades with phenol exposure.	D
Urethane	Swelling and degradation.	C
V-Grooved Iron	Minor corrosion possible.	B

Conclusion

Phenol is compatible with Polyolefin and Ductile Cast Iron wheels (A ratings). Avoid Rubber and Thermoplastic Rubber (D ratings) due to degradation. For assistance, contact CasterTech.
