PA6/PA66 Blend

Sample

Protective caps said to be made of a PA6/PA66 blend

 

Conditions

Measuring cell: DSC20

Pan: Aluminum standard 40 μl, pierced lid

Sample preparation: Disk cut from cap (15.9 mg)

DSC measurement: Heating from 30 to 300 ‎°C at 10 K/min

Atmosphere: Nitrogen, 50 cm3/min

The contents can be estimated from the peak areas if the respective heats of fusion are known (or can be estimated). If one assumes that the heat of fusion for both materials is 45 J/g (typical for polyamides), contents of 35% and 38% are calculated for two polymers. More accurate results could be obtained through calibration with blends of known composition. 


Conclusion

The protective caps are in fact made of a PA6/PA66 blend. The peak areas allow a semiquantitative analysis of the two polymers to be made.
