Polymer Identification (Poly ID) Testing Available at ARDL Using the Following Methods:

ASTM D 3677
Standard Test Methods for Rubber--Identification by Infrared Spectrophotometry

Polymer Identification Description:

There are two major ways to identify the polymer using Fourier Transform Infrared (FTIR), by the examination of pyrolysis products or cast films. In either case the sample is extracted with an organic solvent to remove the organic additives (plasticizers, antioxidants, antiozonants, waxes, etc.) and purify the polymer. The polymer is then thermally degraded and the resulting pyrolyzate is examined using infrared spectroscopy. If a cast film is desired, usually a must when attempting to identify polymer blends, then the extracted polymer is dissolved in a suitable solvent, filtered, and cast on either a potassium chloride or sodium chloride plate and examined using infrared spectroscopy. The resultant infrared spectrum is then compared to known reference spectra that have been generated at ARDL to identify the polymer or polymer blend.

ARDL can test to additional standardized specifications as well as custom specifications. If you are interested in a method that is not listed here, please do not hesitate to call (330) 794-6600 or toll free (866) 778-ARDL to find out if we can perform your test. Chances are we can help and if not, we may know someone who can.
