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 solution and viscometer are placed in a constant temperature water bath. The ratio of the difference between the viscosities of solution and solvent to the viscosity of the solvent.

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

Thermal equilibrium is obtained within the solution. Highly crystalline forms of Aztm that are not soluble in this solvent mixture will require a different procedure. Solvent and solution flow times are measured at 30 deg.

The polymer is first weighed and then dissolved in an appropriate solvent. ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. Using these integrated options ensures full integrity of data from end to end in the ast, process.

Dissolution is carried out using a reaction block with stirring and heating at deg. Historical Xstm s – view previous versions of standard. We reserve the right to update or change our privacy policy at any time and you should check this privacy policy periodically.
