PETG
What is PETG?
PETG, glycol-modified polyethylene terephthalate, is a copolyester that is a clear amorphous thermoplastic. PETG sheet has high stiffness, hardness, and toughness as well as good impact strength.
Unstressed PETG exhibits good resistance to dilute aqueous solutions of mineral acids, bases, salts, and soaps. PETG also has good resistance to aliphatic hydrocarbons, alcohols, and a variety of oils. Halogenated hydrocarbons, low molecular weight ketones, and aromatic hydrocarbons dissolve or swell this plastic.
PETG does not contain a UV inhibitor and it is not suggested for use in applications involving continuous long-term outdoor exposure.
PETG / Spectar® Co-polyester sheet is a thermoplastic sheet used in engineering applications. PETG offers the capability to produce complex shapes, precise details, deep draws and compound curves without worrying about durability. It’s easily formed, die-cut and punched. It brings increased design freedom and lower fabrication costs. In sheet form, PETG has the impact strength and fabrication ease that acrylic can’t touch, with the durability to significantly reduce packaging and shipping costs.
