Mooney viscosity, scorch and relaxation (ISO 289-1 until 4)

Mooney Viscometer (MV2000E)


In order to be processable in practice, the viscosity of unvulcanised rubber compounds must not be too high. Secondly, they must have a sufficient flow rate. That is the time necessary for a compound to flow and take the shape of the mould. This must occur before vulcanisation starts.


The test is carried out according to ISO standard 289-1 until 4 unless otherwise desired.
