Does anyone know what kind of plastic is used for the cheap Halloween masks? I have a conquistador helmet that I want to modify, but I don't want to destroy it using the wrong adhesive.

I will in the future a mold of it, but I want to use it for a costume party that is coming up soon.

If it's that really thin dime store stuff you're talking about then it's usually styrene. If you have a scrap of it you can test using some liquid cement or even lacquer thinner.

If it's thicker and flexible then it's probably polyethylene, which would take something like Tech-Bond to glue.

Agreed. Dime-store style masks (with the rubber band holding it to your head) are usually made of vacuform styrene. I have a Boba Fett costume at home that has a plastic helmet that I'm pretty sure is slightly thicker styrene, but the halves are held together with Velcro.

I'm going to assume its styrene and test it as such. It's a hat, but it feels like the same cheap plastic masks that had a rubber band to stay in place. It's white on the inside, with cheap silver paint on the outside. No markings.
