HEPTACHLOROBUTENE Resistant O-Rings and Seals
Heptachlor, also known as HCB or heptachlorobutene, is an organochlorine insecticide used commonly in the agricultural industry. It was also used as a wood preservative and fire retardant until it was banned in the United States in 1988. Common uses of heptachlor include pest control in crops and livestock, as well as termite prevention.
When rubber is exposed to heptachlor, the material can become brittle and prone to cracking. Over time, the rubber can become stiff and less flexible, resulting in decreased performance and eventual failure. The rubber can also become discolored and develop a foul odor. If the rubber is exposed to high concentrations of heptachlor, it can become corroded and eventually disintegrate and break down.
