How To Keep Rubber From Dry Rotting Work Guide

Rubber under tension (stretched, bent, or compressed) cracks faster than relaxed rubber.

Sunlight is a rubber assassin. If an item is stored near a window or outdoors, it is dying. how to keep rubber from dry rotting work

| 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. | Rubber under tension (stretched, bent, or compressed) cracks

Look for water-based UV blockers (like 303 Aerospace Protectant). Apply a thin layer every 3 to 5 months. | Cause | Mechanism | |-------|-----------| | |
