We offer cohesion testing of silicone gel according to ISO 14607:2024 Annex E. In this test, only the filling is examined, not the shell. The silicone filling material is poured into a funnel with standardized dimensions and surface roughness. The gel is allowed to flow freely through the funnel’s lower opening for a duration of (30.0 ± 0.1) minutes.

During the test, it is observed whether the flowing filling material separates from the remaining volume in the funnel. If the material remains cohesive as a whole, the length of the portion hanging below the funnel is measured. We would be happy to provide you with a quotation for this test.
