Sealing material developments from Trelleborg Sealing Solutions include an EPDM that provides a unique combination of outstanding elasticity with unrivaled compatibility in hydraulic fluids, a perfluoroelastomer that offers best-in-class thermal stability and an innovative lightweight silicone material. In addition, the company releases test results on elastomer seal materials in SPK fuel applications.
In brief:
E8T89 Ethylene Propylene Diene Monomer (EPDM) seal material provides a unique combination of outstanding elasticity at low temperatures with unrivaled compatibility in all commercially available phosphate ester hydraulic fluids.
Perfluoroelastomer Isolast® J9577 gives outstanding performance at high temperatures, offering best-in-class thermal stability, even in aggressive HTS oils.
12-205LD, an innovative lightweight silicone material, is typically 20 percent lighter than standard silicones used for aerospace seals.
A study shows care must be taken when specifying elastomer seal materials in aerospace synthetic paraffinic kerosene (SPK) fuel applications.
