PET – Intrinsic Viscosity – ASTM D4603
You have no items to compare. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements. Commonly a sample size of mg. Solvent and solution flow times are measured at 30 deg. Link to Active This link will always route to the current Active version of xstm standard.
The property of resistance of flow exhibited within the body of a material. Using these integrated options ensures full integrity of data from end to end in the measurement astn.
PET – Intrinsic Viscosity – ASTM D – RPV-2 Polymer Viscometer – Automated Viscometers
Log data Like many other site operators, we collect information that your browser sends whenever you visit our site. Specific hazards statements are given in Section 8. The ratio of the viscosity of the solution to the viscosity of the solvent.
In addition we may use third party services such as Google Analytics that collect, monitor and analyse this data. Thermal equilibrium is obtained within the solution. The values given in parentheses are for information only. The liquid is then brought above the upper graduation mark on the viscometer. The time for the solution to flow from the upper to lower graduation marks is recorded. The RPV-2 software automatically calculates the Intrinsic Viscosity from each single determination using the Billmeyer equation.

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. The ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer. It must be controlled so that the processability and end properties of the resin remain in a desired range. C with a programmable timer.
The polymer is first weighed and then dissolved in an appropriate solvent.
The solution and viscometer x4603 placed in a constant temperature water bath. A cookie is a small file of letters and numbers that we put on your computer if you agree.
