Please Note: This product has protective films on both sides of the sheet. These films should be removed prior to usage/installation. PET-G is a food-safe, high strength, heat formable, crystal-clear thermoplastic ideal for vacuum forming or shaping over hard forms to create ultra light-weight hollow forms to be lit (such as gemstones), visors and displays for helmets and props or even creating smooth light reflectors for LED lights by using a mirror paint and block-out paint. Note: PET-G is NOT self-adhesive. Compared to Worbla's transpart, significantly higher heat is required to activate its shapeable and stretchable properties. For this reason, it is recommended that you use heat-proof gloves when handling the material. Properties: Vacuum forming Temperature: 150-250C Optically Clear Food Safe Flexible
