Rubber Mooney Viscometer Used for Measuring Viscosity And
Relaxation of Base rubber, Raw rubber
- Character
Mooney Viscometer is used for measuring viscosity and relaxation of
base rubber, raw rubber stock or rubber mass prevulcanization
properties, it is also used for measuring viscosity in Mooney value
for compounded or uncompounded unvulcanized natural, synthetic or
regenerated rubber.
This instrument has excellent performances including automatic
calibration, higher stability. It can perform the following tests:
viscosity, scorch and stress relaxation.
2. Test standard
Accord with GB/T1232"Rubber unvulcanized -Determination of mooney
viscosity'',GB/T 1233 ''Rubber,unvulcanized-Determination of
prevulcanization characteristics-Shearing disk
method'',ISO289,ISO667ect.
