Performance characteristics : HNBR has higher heat resistance, ozone resistance, chemical resistance and mechanical properties than standard NBR
Operating temperature : -40 ° C~180 ° C
Hardness range : 50~90 Shore A
Scope of application : Most commonly used in R134a refrigerant or new refrigerants ( such as R401a , R404a , R410a , R507 and R744) to protect the environment in automotive air conditioning systems. Due to its excellent wear resistance HNBR is also used in automotive axle systems. In the oil extraction process, the material is required to have good heat resistance, crude oil resistance, H2S resistance, steam resistance and anti-knock type. Specially formulated HNBR can be applied to such working conditions.
Applicable medium : petroleum base oil and fuel oil, ethylene glycol, aliphatic hydrocarbon, medium temperature diluted acid-base and salt solvent, vegetable oil, water and steam, silicone oil and silicone grease Unsuitable medium : chlorinated hydrocarbons, ketones, ethers, Esters, strong acids, strong bases.
