ISOBUTYLENE Resistant O-Rings and Seals
Isobutylene, also known as isobutyl phosphate, is a colorless, flammable liquid that is used in a variety of industries such as agriculture, automotive, and aerospace. It is used as a reagent, fuel, solvent, and other industrial applications. Common applications include coating and curing of rubber, plasticizers, and plasticizers in adhesives.
Common types of failures when rubber is exposed to isobutylene include cracking, shrinking, hardening, and embrittlement. These failures are the result of the chemical’s ability to accelerate the aging of rubber. The chemical also affects the physical properties of rubber, such as its tensile strength, elongation, and tear strength. Additionally, exposure to isobutylene can cause rubber to become discolored or have an unpleasant odor.
