PVC and PVDC identification Testing.

the best combination of PVC with PVDC. We follow some testing parameters to identify the PVC and PVDC

PVC (polyvinyl chloride) Foil  

Physical

  • Pvc is made of versatile synthetic polymer
  • Pvc made of chloromethane monomer
  • The term PVC stands for polyvinyl chloride
  • The repeating units have a C-Cl bond
  • The PVC is low cost and the ease of thermo-forming
  • The PVC is a poor barrier against moisture ingress and oxygen ingress
  • Moreover the pvc has a negative environmental connotation due to chlorine content
  • It is used in certain packaging applications where barrier properties are crucial

Chemical Identification:

  • Pvc foil

  In this test, we take a sample of PVC foil, and a few drops of morpholine regent on the PVC foil after some time, with no color change.

                                                                                               NO color apperared

Identification by FTIR:

    In this testing, we perform with the help of FTIR Instrument, First scan standard, and compare with the same wavelength of the sample.

What is PVDC (Polyvinylidene chloride)

  • The PVDC is a type of vinyl polymer
  • The term PVDC stands for polyvinylidene chloride
  • The Repeating Units have C-Cl bonds
  • Its monomer is vinylidene chloride
  • It is used as a coating in packaging material to protect food and pharmaceutical products.
  • Protect from oxygen and moisture the extending their shelf life

Chemical Identification

PVDC side

  In this test, we take a sample of PVDC side sample, a few drops of morpholine regent on the PVdC foil after some time, a yellow color is produced. a pigment color small

PVDC MORPHILINE TEST

                                                                           After morpholine  yellow colour appered

Identification by FTIR:

    In this testing, we perform with the help of FTIR Instrument, First scan standard, and compare with the same wavelength of the sample.

     Below the FTIR Graph is the PVDC
