Re-cycled PET

The PSL Rheotek RPV-2 is ideal for determining the viscosity of re-cycled PET, which may contain a high level of particulates. PET samples can typically range from 0.5 to 1.2 dL/g and results will be reported to 3 decimal places.

The RPV-2 determines the Inherent Viscosity of Poly (Ethylene Terephthalate)/PET in dilute solution using glass capillary viscometers in accordance with ASTM D4603. The test method requires a 0.5% concentration of PET dissolved in 60/40 phenol/1,1,2,2-tetrachloroethane solution.

Solvent and solution flow times are measured at 30 deg. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements. The method requires that three successive flow times are obtained within 0.2s of the mean.

The RPV-2 software automatically calculates the Intrinsic Viscosity from each single determination using the Billmeyer equation.

The RV-2 (2) AutoPET is an ideal configuration for measuring re-cycled PET. The configuration includes

- Integrated sample prepration

- Integrated sample dissolution

- Integrated flow time measurement

- Integrated cleaning of viscometers in-situ

- Full reporting of IV results
