Polymer Testing with METL
METL OFFERS several tests to IDENTIFY polymers including FTIR-ATR. We also have the capabilities to examine additives, determine the presence of defects, and conduct failure investigations. Let us help you analyze YOUR MATERIALS.
FTIR-ATR
Fourier transform infrared (FTIR) spectroscopy can identify the characteristic bonds within a plastic, rubber or other organic material. Taking advantage of attenuated total reflectance (ATR), we can determine the family of your material with minimal damage to the sample.
Applicable Specifications
ASTM E1252
Specific Gravity
For some polymers, specific gravity can be the difference between two distinct types. Specific gravity can also indicate if porosity or other defects are present in the sample.
Applicable Specifications
ASTM D792
Shore Hardness
We measure the hardness of polymers in the Shore A and Shore D scales using calibrated durometers. Shore hardness is a standard property for many polymers and can be used to qualify or characterize some families of materials.
Applicable Specifications
ASTM D2240
Cross-section Examination
Samples can be precision sectioned through a plane and examined with an optical microscope up to 1000x magnification. Cross-sections can be examined at higher magnifications using electron microscopy methods (SEM-EDS). Examinations could consist of quality inspection, additive determination, or coating evaluation/measurement.
Applicable Specifications
ASTM E3
Scanning Electron Microscopy (SEM)
Scanning electron microscopy (SEM) can be used on organic materials after gold sputter-coating the surface. SEM allows for fractography of failures or high magnification inspections.
Scanning Electron Microscopy (SEM)
Scanning electron microscopy (SEM) can be used on organic materials after gold sputter-coating the surface. SEM allows for fractography of failures or high magnification inspections.
Energy Dispersive X-Ray Spectroscopy (EDS)
Energy dispersive x-ray spectroscopy (EDS) can help distinguish between a carbon-based matrix and additives of other compositions such as glass fibers, PTFE or molybdenum-disulfide dry film lubricants.
Applicable Specifications
ASTM E1508

Commonly Asked Questions
Does FTIR-ATR provide chemical composition?
FTIR-ATR provides spectra that reveal characteristic molecular bonds that are unique to families of polymers. With polymers being organic in nature, composition would not be very helpful, as many will show almost 100% carbon content.
Can METL tell me an exact formula match for my polymer?
Many formulas are proprietary and not easily determined. While exact industry matches will not be provided, METL can provide you with the family of material and determine certain physical properties that can help narrow down material types.
IS FTIR-ATR non-destructive?
In short, yes. The scanning of material using FTIR is non-destructive but depending on sample geometry, the material may require to be ground, sectioned or polished prior to testing.
