Selection of Neoprene Type and Grade The various grades of Neoprene fall within three types, e.g., G, W and T. Within each type there is a series of grades that differ primarily in resistance to crystallization and Mooney viscosity. Selection of type and grade is usually based upon a combination of four factors: Product performance

This part of ISO 289 specifies a method using a shearing-disc viscometer for measuring the Mooney viscosity of uncompounded or compounded rubbers. 2 Normative references. The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition .2.3. Mooney Viscosity Mooney viscosity measurements were carried out using a Wallace MKIII viscometer at 100ºC. The sample weights were in the range of 25-30g. The Mooney viscosity was recorded for compounds at the masterbatch, remill and finalised stage. The testing was conducted based on the ISO 289-1 standard. 2.4. Cure Characteristics To that end, we investigated Mooney torque relaxation. The Mooney viscometer is an inexpensive instrument (cost and maintenance) that is easy to use and, above all, available in the great majority of factories producing natural rubber. The measurement of NR Mooney viscosity is governed by international standard ISO 289.The Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. As defined by international standards, the sample material is preheated for a defined period in a closed die cavity, then sheared by the embedded rotor at a constant rate.

Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference .
However, if the Mooney viscosity is too low, the physical and mechanical properties of vulcanized products are poor. From the Fig. 4, we can see that with the extension of storage time, the Mooney viscosity of NR shows an increasing trend. The Mooney viscosity of NR goes from 76 to 83 with storage time from 0 to 48 h with a rate increase of 9.21%.
