PROPERTIES OF Hydrocarbon Elastomers NITRILE |
 |
| Description:
Standard Nitrile is also known as Buna-N. Excelent resistance to
petroleum-based oils and fuels, water and alcohols. Nitrile also has good
resistance to acids and bases, except those with a strong oxidizing
effect.
Limitations: Avoid highly polar solvents (Acetone, MEK, etc.) and direct exposure to ozone and sunlight. Chemistry: Copolymer of butadiene and acrylonitrile. By varying the acrylonitrile content, elastomers with improved oil/fuel swell or with improved low-temperature performance can be achieved. Specialty versions of carboxylated high-scrylonitrile butadiene copolymers (XNBR) provide improved abrasion resistance. And hydrogenated versions of these copolymers (HNBR) provide improved chemical and ozone resistance elastomers. Trade Names: CHEMIGUM®, HYCAR®, PARACRIL®, PERBUNAN® Temperature Range: -55º to 120ºC (-65º to 248ºF) |
