Mooney Viscometer DMV2025 manufacturer will show you that Mooney Viscometer cannot accurately calculate molecular weight
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney viscosity measured by the Mooney Viscometer reflects the degree of polymerization and molecular weight of synthetic rubber. Mooney viscosity reflects the quality of rubber processing performance, the level of molecular weight and the wide range of distribution. The compound with high Mooney viscosity is not easy to be mixed uniformly and extruded. Its molecular weight is high and the distribution range is wide. The manufacturer of Mooney Viscometer DMV2025 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. The manufacturer of Mooney Viscometer DMV2025 tells you that if the Mooney viscosity is too low, the tensile strength of the cured product will be low. The Mooney viscosity-time curve can also see the performance of the rubber vulcanization process.
The manufacturer of Mooney Viscometer DMV2025 tells you that the 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 beneficial to the rubber. Mixing, calendering, extrusion, injection and molding vulcanization and other processing technology, so that the vulcanized rubber can obtain good physical and mechanical properties, so the Mooney viscometer is a very common testing instrument in the rubber industry. The viscosity mainly affects the processing performance. The high Mooney viscosity has certain difficulties in the mixing and extrusion process, but the high viscosity and high shear force result in excellent mechanical properties of the final compound.
The manufacturer of Mooney Viscometer DMV2025 tells you that Mooney viscosity cannot accurately calculate molecular weight because it can only reflect the size of molecular weight. If you want to accurately determine the molecular weight, you can use capillary method, osmotic pressure method and other methods to get it.
