Excessive heat dries out the essential oils in rubber, while extreme cold makes it brittle.
Aerospace seals, chemical processing valves, and high-heat gaskets.
Atmospheric ozone attacks polymers, especially when rubber is under tension. how to keep rubber from dry rotting work
Proper storage is your first line of defense for spare parts, hoses, and rubber protective gear:
For vehicles or heavy equipment parked for long periods, lift them on jacks to take the weight off the rubber tires, or move them slightly every few weeks. Industry-Specific Applications Excessive heat dries out the essential oils in
Tiny, spiderweb-like cracks appearing in high-stress areas (such as bends or sidewalls).
Dry rot in rubber is not caused by a biological fungus like wood dry rot. Instead, it is a form of chemical degradation known as oxidation and ozonolysis. Proper storage is your first line of defense
Rubber is a durable material, but it is highly susceptible to environmental stress. When rubber loses its internal oils and moisture, it becomes brittle, cracks, and eventually fails—a process known as dry rot. For those who rely on rubber-based equipment for work, such as tires, gaskets, hoses, or safety boots, prevention is significantly cheaper than replacement. Understanding Why Rubber Dry Rots
Use a marine-grade rubber protectant or a dedicated silicone-based conditioner.
You will see many "hacks" online about fixing rubber. Let’s clear up two common ones:
Never use petroleum-based cleaners, acetone, or harsh industrial solvents.
