Wonder what kind of plastic it is? Many common plastics aboard the boat are thermoplastic. Most of them have poly in their names. Their attribute as a solid is that they can be softened or melted (and repaired.) This info comes from a manufacturer of thermoplastic welding rod.: V&A Process Inc. www.vandaprocess.com Thanks!
PVDF - (Kynar, sweet water piping, pumps, film) Polyvinylidene Flouride - Produces an acrid odor and will burn to a black ash. Flame will self extinguish.
TPU - (hard and stiff housings, bumpers, air-cell cushions/mats - sputters when burning) - Polyurethane - Produces a yellow flame, slight black smoke and a faint apple-like odor. Flame will not self-extinguish.
ABS - (Drains, plumbing, helmets, tattoo inks) Acrylonitrile Butadiene Styrene - Produces a black smoke, soot flakes and an acrid smell. Flame does not self-extinguish.
PVC - (pipe, conduit, hoses, insulation) Polyvinyl Chloride - Produces a black medium smoke and an acrid smell. Flame will not self-extinguish.
PE - (plasteak, film/bags, tanks, toys, bottles) Polyethylene - Produces no smoke. Material drips like a candle and smells of wax. Flame will not self-extinguish.
PP - (nearly everything) Polypropylene - Produces no smoke. Material drips like a candle and smells of burnt oil. Not self extinguishing.
PC - (glazing, glasses) - Polycarbonate - Produces a yellowish sooty smoke and smells sweet. The flame WILL self-extinguish.
PS - (foam, basins, toys, electronics cases) Polystyrene. Produces a yellow flame, sooty smoke and smells of illuminating gas*. Material drips. Flame will not self-extinguish.
Everything in this block is quoted except items in parenthesis ().
*aka coal gas, wrong century, maybe they mean it has a methane (fart) odor?
Somebody could put together a less incendiary scratch-and-sniff ID list based on grinding or scraping room-temperature plastic.
It might be useful to record the odor of these plastics when they're hot and befor they actually burn.
Much plastic is also recognisable from its sheen - if how a plastic looks can be put into words. The full list would include our synthetic rubbers, caulk, gasket and hose - what they smell like when they're cooking.
Would also be good to line our friends up in order of their toxicity when they are smoking. (It might be lethal to go below to put a fire out, if you breathe!) One very dangerous material when burning is urethane foam (a thermoset - doesn't melt) - altho you won't hear it from the industry. It produces a "first cousin to Phosgene Gas" and quite simply turns you into a statistic.
It would be great to see the info in a usable chart form.
