How To Keep Rubber From Dry Rotting Work _verified_ -

| Rubber Type | Susceptibility | Best Preventive | |-------------|---------------|------------------| | | Very high (high double bond content) | Airtight, cool, dark, talc | | EPDM | Low (ozone-resistant by design) | UV block (some grades still crack in sunlight) | | Silicone | Very low (no double bonds) | Keep clean; high heat tolerance | | Nitrile (Buna-N) | Moderate (oil-resistant, but ozone susceptible) | 303 Protectant; avoid fuel vapors | | Neoprene | Low–Moderate | UV block; good general purpose |

Standard "shining" products often contain silicone or petroleum that can actually worsen dry rot over time. how to keep rubber from dry rotting work
