Mylar and/or polyester film with a coating of metallic particles bonded with a polymer resin. It burns, not very fast, but with an intense heat. The fumes are moderately toxic. The metal particles, if inhaled, are more toxic. The fire is difficult to put out. Some years ago, a video tape processing facility near here caught fire. The fire was so intense, they could not put it out. It burned for 2 days. The main storage vault, which was guaranteed to withstand a fire for 24 hours, burned also. It was a total loss. - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail cbm-hackers-request@dot.tcm.hut.fi.
