There is no label on the plastic product indicating which type of plastic (Pve, pp, pe...) is there any mechanism or method that can detect which type it is. I can accept paid testing.

No best answer

1.There are currently two main places where you can choose to test: universities and testing institutions. If you only need a result, you can choose universities. Many universities have related institutions that can test results. In addition, third-party testing institutions can choose. Formal third-party testing agencies, sgs and both STAND and Kechuang can do.
2.Infrared spectroscopy, nuclear magnetic resonance.
Electron probe, ion probe, Auger electron spectrometer, the above three are used for surface chemical composition analysis. Ion probes have great damage to the sample, the Auger is small, and the electrons are generally not.The chemistry school, polymer school or material school of each university should work.
