Clear PETG Plastic Sheet
PETG (Polyethylene Terephthalate Glycol) is a clear thermoplastic polyester that provides significant chemical resistance, durability, and excellent formability for manufacturing.
PETG is a thermoplastic meaning various shapes and objects can be produced from this material using a vacuum former and can be useful for mould making.
The thickness of the material needed is dependant on the form you are looking to make and it is worth taking advice on this from the relevant RCA technician if you are unsure.
