How can differentiate between ABS cards and PVC cards in an easy way?
Is using flaming (burning) considered a reliable method?:rolleyes:

Burning might be a reliable method. PVC, poly vinyl chloride, should be much less flammable than ABS, acrylonitrile-butadiene-styrene copolymer.

If I had the equipment available, I'd probably use infrared spectroscopy. I'd probably grind some up and make a flat pellet in KBr and then take a spectrum of the material. The differences should be very significant.
