DIISOBUTYLENE, also known as DIB, is a colorless liquid hydrocarbon that is used primarily as a synthetic intermediate in the production of plasticizers, lubricants, and other industrial products. It is also used in the production of synthetic rubber and as a fuel additive.
When rubber is exposed to DIISOBUTYLENE it can cause swelling, softening, and other issues. It can also lead to cracking, hardening, and other forms of failure. Furthermore, DIISOBUTYLENE can cause rubber to become brittle, leading to leakage and other problems. In general, it is best to keep rubber away from DIISOBUTYLENE and other chemicals as much as possible.
