How To Keep Rubber From Dry Rotting Work 'link' Review
To keep rubber from dry rotting, you must protect it from its three main enemies: extreme heat harsh chemicals
Tires/Hoses: Park in the shade when possible; use UV-blocking sprays. how to keep rubber from dry rotting work
- Definition: Dry rot refers to the cracking and hardening of rubber caused by the loss of plasticizers and the breakdown of polymer chains.
- Visual Signs: Fine, hairline cracks on the surface, a chalky or brittle appearance, hardening of the material, and eventual crumbling or snapping under stress.
- Chemical Cause: The primary driver is oxidation. When rubber is exposed to oxygen, ozone, and UV light, the molecular bonds break down. This process is accelerated by heat and cycles of expansion/contraction.
. Regular maintenance—specifically cleaning and conditioning—is the most effective way to prevent the rubber from becoming brittle and cracking. hunterboots.com.au 1. Routine Cleaning To keep rubber from dry rotting, you must
- Ozone (O3): Even trace amounts in the air attack double bonds in rubber polymers. As rubber flexes (like a bending hose or rotating tire), microscopic cracks form that ozone widens.
- UV Radiation: Sunlight breaks polymer chains. This is why the sunny side of a rubber seal fails first.
- Heat: Every 18°F (10°C) increase doubles the reaction rate of oxidation.
