ISOBUTYRIC ACID Resistant O-Rings and Seals
Isobutyric acid, also known as 2-methylpropanoic acid, is a colorless liquid with a pungent odor. It is used as a food preservative and as a solvent in the production of plastics and pharmaceuticals.
Common types of failures when rubber is exposed to isobutyric acid include swelling, cracking, hardening, and embrittlement. Additionally, isobutyric acid can cause discoloration of rubber, affect its physical properties such as tensile strength, elongation, and tear strength, and cause an unpleasant odor.
HNBR (HSN, Hydrogenated Nitrile)
HNBR, or hydrogenated NBR, is created by modifying the properties of NBR to increase the materials resistance to ozone, many chemicals, heat, aging, and abrasion. Like NBR, HNBR still holds onto its resistance to oils and fuels.
