How to prevent rubber from dry‑rotting

Ozone

| Cause | Mechanism | |-------|-----------| | | Attacks double bonds in rubber (especially natural rubber, nitrile, SBR). Causes surface cracks perpendicular to stress. | | UV Light | Breaks carbon-carbon bonds, generates free radicals, leads to surface chalking and cracking. | | Heat | Accelerates oxidation and volatilizes protective plasticizers (Arrhenius behavior: rate ~doubles per 10°C rise). | | Humidity extremes | High humidity can leach antioxidants; low humidity accelerates plasticizer loss. | | Stretching/Stress | Opens microscopic cracks for ozone to penetrate deeper. |

| Action | Effectiveness | Difficulty | Best for | |--------|--------------|------------|----------| | Store in cool, dark, dry place | ★★★★★ | Easy | All rubber | | Use 303 Aerospace Protectant | ★★★★☆ | Moderate | Tires, seals, trim | | Vacuum seal with oxygen absorber | ★★★★★ | Moderate | Spare parts, gaskets | | Wrap in aluminum foil | ★★★★☆ | Easy | Hoses, belts, small parts | | Apply silicone grease (non-spray) | ★★★☆☆ | Easy | O-rings, plumbing seals | | Avoid all petroleum products | (Preventive) | Easy | All rubber | how to keep rubber from dry rotting work

Conclusion

Stagnation is also a killer. Rubber that sits motionless for years undergoes "compression set"—it loses its ability to rebound. Aged rubber often cannot be reprocessed into high-value
