The indicated material properties at measured values are mean values determined with standard test bars. They may not be used as
specification values and they are not directly comparable to material properties of finished parts. This is to emphasise that the customer
himself is obliged to test the material with regard to its suitability in the application. This data sheet has not a change of service.
Die unter Istwert angegebenen Kennwerte sind Mittelwerte und wurden an Normprobekörpern bestimmt. Sie dürfen nicht als
Spezifikationswerte verwendet werden. Auch sind sie nicht mit am Fertigteil bestimmten Kennwerten vergleichbar. Der Abnehmer ist
insbesondere nicht davon befreit, selbst die Eignung unserer Ware für den beabsichtigten Verwendungszweck zu prüfen. Das Datenblatt
unterliegt nicht dem Änderungsdienst.

Trelleborg Sealing Solutions Malta material reference 2662 is an Ethylene-Propylene (EPDM) based
compound designed to give excellent service in brake fluid application including A.B.S. systems.
2662 should not be used in contact with mineral based oils, lubricants or hydrocarbon fluids.
ASTM D2000 M2CA 714 A25 B35 B44 EA14 Z1 Z2 where
Z1 = Retraction @ low temperature (ASTM D1329) -40°C
Z2 = Aging in Brake fluid DOT 4, 70 hrs @ 125°C volume change +2 to +10%
Compound Key Properties include:
- Compatibility to glycol type of brake fluids.
- Positive swell in Brake fluid.
- Low compression set and good heat resistance.
- Good resistance to ozone and weathering.
- Good low temperature flexibility.
- Resistance to hot water and steam.
- Projected service temperature range of -50 to +140°C which is dependant upon
medium to be sealed and conditions of service.
Possible Applications:
- Brake systems.
- A.B.S. Brake 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 particular
conditions of operation.
