DMV2025 manufacturers take you to understand the relationship between rubber Mooney viscosity and processing performance
DMV2025 manufacturers tell you that Mooney viscosity, also known as rotational (Mooney) viscosity, is a value measured with a Mooney viscometer, which can basically reflect the degree of polymerization and molecular weight of synthetic rubber.
DMV2025 manufacturers tell you that Mooney viscosity reflects the quality of rubber processing performance, molecular weight and distribution range. The DMV2025 manufacturer tells you that the high Mooney viscosity rubber compound is not easy to mix evenly and extrude, and its molecular weight is high and the distribution range is wide. The DMV2025 manufacturer tells you that the low Mooney viscosity rubber is easy to stick to the roller, and its molecular weight is low and the distribution range is narrow. If the Mooney viscosity is too low, the tensile strength of the vulcanized product will be low. The time curve can also show the vulcanization process performance of the rubber compound.
The DMV2025 manufacturer tells you that Mooney viscosity mainly affects processing performance. Mooney viscosity is high, and there are certain difficulties in the mixing and extrusion process, but the viscosity is high, the shear force is large, and the mechanical properties of the final compound are excellent.
The DMV2025 manufacturer tells you that Mooney viscosity value is closely related to plasticity. A high viscosity value indicates that the rubber has a large molecular weight and poor plasticity. On the contrary, the rubber has a small molecular weight and good plasticity. Reasonable control of the rubber Mooney viscosity value is conducive to the mixing of rubber. , calendering, extrusion, injection and molding vulcanization and other processing processes, so that the vulcanizate can obtain good physical and mechanical properties.
