PET – Intrinsic Viscosity – ASTM D – RPV-2 Polymer Viscometer – Automated Viscometers

It is used for polymers that dissolve completely without chemical reaction or degradation and can provide an excellent determination of lot-to-lot consistency or be used to compare molded parts to original resin for determinations of degradation from molding. Standards can be obtained from appropriate standards authorities. My Account Log In. The ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer.

If the material is filled, it is important to specify percent filler. The property of resistance of flow exhibited within the body of a material. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Dilute Solution Viscosity of Polymers. A cookie is a small file of letters and numbers that we put on your computer if you agree. Commonly a sample size of mg.

It must be controlled so that the processability and end properties of the resin remain in a desired range. The limiting value of the reduced viscosity or the inherent viscosity at infinite dilution of the polymer. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements.

ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. Contact us If you have any questions about this privacy policy, please contact us. The time for the solution to flow from the upper to lower graduation marks is recorded.

The liquid is then brought above the upper graduation mark on the viscometer. The RPV-2 software automatically calculates the Intrinsic Viscosity from each single determination using the Billmeyer equation.
