Hardness Range : 65 - 75 IRHD
Dowty Automotive (Malta) Ltd. material reference 2716 is based on a Hydrogenated Nitrile (HNBR)
polymer specifically designed to have the maximum heat resistance possible with this class of elastomers.
Compound Key Properties include :
-
High mechanical properties.
Good heat resistance.
Resistant to mineral oils.
Good resistance to hot water.
Good resistance to ozone and weathering.
Resistant to refrigerants (R12/R134a) and lubricant oils, ( Mineral oil /PAG)
Projected service temperature range of -30 to +150°C which is dependant upon medium
to be sealed and conditions of service.
Applications :
-
Hydraulic and pneumatic.
Cooling/Heating systems.
Air Conditioning ( R134a /PAG)
Under bonnet / engine.
The information herein is accurate to the extent of our current technical knowledge. Dowty Automotive (Malta) Ltd. makes no
warranty that the material is suitable for all applications. Customers should undertake their own tests to ensure suitability for
particular conditions of operation.
