1, Appearance.
There is no obvious difference between the appearance of the finished product and the standard sample. The particle length is between 4 and 8 mm. There are no triple particles, basically no debris, no foreign bodies and impurities, and no undispersed aggregates and colloids.
2, Sulfur content.
The sulfur content of pre-dispersed rubber auxiliaries mainly characterizes the content of active components in the products, and only part of the products need to be determined.
3, Density.
The density of pre-dispersed rubber auxiliaries has a certain relationship with the properties of raw materials, the dispersion during processing and the content of anti-adhesive.
4, Mooney viscosity.
The Mooney viscosity of the pre dispersed rubber agent represents its storage, transportation and processing properties.
5, Dispersion.
The dispersibility of rubber auxiliaries in pre-dispersed rubber auxiliaries has a direct impact on the stability of rubber products, and its groups have a greater impact on energy production. Therefore, it is necessary to investigate the dispersibility of pre-dispersed rubber auxiliaries.
