Trelleborg Sealing Solutions Malta material reference 2751 is an Ethylene-Propylene (EPDM) based
compound designed to give good resistance to hot water and non-mineral based fluids such as anti-freeze &
glycol type brake fluids.
2751 should not be used in contact with mineral based oils, lubricants or hydrocarbon fuels.
Compound Key Properties include:
-
Low compression set and good heat resistance.
Good resistance to hot water and steam.
Good low temperature properties.
Good resistance to water/anti-freeze mixtures.
Good resistance to ozone and weathering.
Projected service temperature range of -50 to +140°C which is dependant upon
medium to be sealed and conditions of service.
Possible Applications:
- Heating and ventilation systems.
- Water fittings.
- Cooling systems.
The information herein is accurate to the extent of our current technical knowledge. Trelleborg Sealing Solutions Malta Ltd makes
no warranty that the material is suitable for all applications. Customers should undertake their own tests to ensure suitability for
