Next important question...! How do these polymolecular polyester
polyurethanes affect the chemical reactions inherent in the chemical
process of "life"...human and/or otherwise...?!

No reports that I have seen identify these as harmful to life, but the usual precautions apply -- i.e. wash your hands before meals, avoid breathing fumes (I wear a respirator when I'm dealing with moldy tapes, but the breakdown products don't seem to fly all over the place), etc.


As I understand it, the broken chains are still mostly captive in the matrix and it takes the energy of pulling the tape past something to get them to come off. I don't think it's like asbestos, for example.

I'm not a doctor nor medical researcher, so if anyone has any better information, I'd appreciate it.

Cheers,

Richard
