EVA Foam Sheets or Puzzle Mats

[brycat]

Looking for a manufacturer in Thailand that sells EVA foam sheets or puzzle mats (as pictured below). Dimensions 1m*1m*5cm or 1m*2m*5cm. I'd prefer to have puzzle mats, but I'd be OK with just the foam sheets if it decreased the price. I've tracked down a couple leads, but can't find anything for less than 550 baht per square meter. I'm pretty sure other sources exist. Any help would be appreciated.

do you mean polyurethane versus polyethylene?

don't matter really but go to any kids store or section in a department stroe you will pick up both sorts
