Gas From Mixed PVC/Delrin Reaction

Nice huge cloud of noxious gas. Turned the nozzle-face white, left residue everwhere and resulted in a visit from the Hazmat people.

What are we dealing with here... besides a clueless idiot?

Dangerous Mixes
Some plastics are reactive at molten temperature and may generate gas. Others can even explode. Examples include: PVC-Acetal, PVC-Santoprene, (1) TPE (or similar product ), Acetal-Santoprene TPE (or similar product), and Acetal-Alcryn (2) synthetic rubber.

PVC-Acetal-TPR, are incompatible. At processing temperature, the TPR (thermoplastic rubber) degrades both the PVC and the Acetal. The HCL (hydrochloric acid) from the PVC will degrade the Acetal and the mix of those two products may create BCME, which is a known carcinogen.

Anyhoo, thanks for that list I gave it to one of my friends at the recycle plant maybe they can avoid this problem down the road provided they don't get shut down first. :)
