ETHYL DIBROMIDE Resistant O-Rings and Seals

Ethyl dibromide, also known as ethylene dibromide, is an organic compound used as an agricultural fumigant and an intermediate in the production of dyes and pharmaceuticals. Common types of failures when rubber is exposed to ethyl dibromide include cracking, swelling, discoloration, and hardening. Cracking is caused by the chemical's ability to penetrate the rubber's surface, weakening the rubber's structure. Swelling occurs when the chemical is absorbed into the rubber, causing it to expand and become less flexible. Discoloration is caused by the chemical reacting with the rubber's surface, changing its color. And finally, hardening occurs when the rubber is exposed to the chemical for a long period of time, causing it to become brittle and less resilient.
