Lexan. Just to be sure... Answered

So, I was thinking about an Halloween mask, a steampunk diving dress. The most complex thing is, of course, the head piece. More specifically, I'm in a bit of a quandary with the visor: I need to make a convex, ellyptical dome of clear plastic. Since I need to fit that into a frame I need to make it from flat panels; this way I'll get the shape I want. I think I'll use Lexan: it seems to be quite sturdy and easy to work on. In theory, all I have to do is heat the thing up to 200°C (400°F) and it will bend like a charm, but I'm a bit worried about exalations and whatnots; can someone help me here please?

many people do similar things for Daft Punk Visors either put it in the microwave (I don't recomend it, but it's what most people do) or user a heatgun, never heard anyone use it but it sounds like it'd work good.

I've thought about building a helmet once, but decided to spend the money on other stuff, lol.

I would just go to a home center or hardware store to get a few replacement faceshields for the full face protectors that construction workers use. They are easy to bend and would be easier to work with than a regular sheet of lexan or acrylic. Maybe you could just find a clear plastic serving bowl for fruit or salads at a party supply place and use that. It is premolded to shape, so you would just need to find the right size. You may get some optical distortion, but its Halloween... Or just cut the bottoms out of plastic soft drink/water bottles and glue/bend them to shape. Good luck.

Aye, it's dead easy, there aren't too many vapours but well ventilated is best used just in case, heating it with a heatgun or in the oven over a bowl so it takes the form of it would probably be the best way to make the actual shape though.

. Most thermoplastics will emit vapors when heated. If not from the plastic itself, then from the various additives. Make sure you do it in a well-ventilated area.
. bisphenol A, a suspected carcinogen, is a precursor and can be found in Lexan.
