Elastomer Testing

Elastomer Testing Seal compatibility with fuel, fuel blends and lubricants is an important part of any fuel fit for purpose assessment. Using rigs developed at the LCCC, the assessment of the dynamic elastomer fluid interaction is possible under compressive loads, simulating the mechanical and thermal loading loading of a seal in service. This unit is able to simulate fuel system conditions and the test is a dynamic process which continuously monitors the stress relaxation behaviour of the material under test at controlled temperatures between -40 and 300°C and with fuel switch loading. This test facility is being used for studying the effect of different fuel compositions, aromatic species and other hydrocarbons on seal performance.
