Butyl Rubber (IIR)
HNBR is a synthetic polymer that is created by saturating nitrile’s butadiene segments with hydrogen. It is popularly known for its toughness and resistance to chemicals, heat, oil.
Salient Features:
- Oil resistant
- Excellent mechanical properties
- Abrasion-resistant
- Low compression set
- Hot air resistant
- Cold flexibility
- Weather and ozone resistant
Common Applications:
- Industrial applications
- Automotive air conditioning systems
- Oil resistant applications
- Static and dynamic hoses, belts, and seals
- Seals for oil well processing and exploration
Properties:
- Hardness: 50-90 Shore A
- Temperature resistance: -30° C to + 150° C (+ 175° C)
- Standard colors: Green, Black
Advantages:
HNBR exhibits good performance in ethylene glycol, vegetable oils, silicone greases, and oils, aliphatic hydrocarbons, dilute acids, steam, or water (up to 150°C), salt solutions, and petroleum-based fuels and oils.
Limitations:
HNBR compounds are prone to strong acids, ketones, esters, ethers, and chlorinated hydrocarbons.
