PETühendid
PETühendid refer to chemical compounds related to polyethylene terephthalate (PET), a widely used thermoplastic polymer. The term can denote derivatives, copolymers and related esters derived from PET, including glycol-modified PET (PETG), branched or crosslinked PET copolymers, and other PET-based materials.
Chemistry and synthesis: PET is formed by condensation polymerization of terephthalic acid (or dimethyl terephthalate) with
Structure and properties: PET and its derivatives are typically clear, strong, and dimensionally stable, with good
Applications: PET is widely used for beverage bottles, food packaging, and textile fibers; PETühendid expand use
Recycling and environment: PET is highly recyclable via mechanical recycling; chemical recycling methods can recover monomers
Safety: PET and common packaging additives are generally regarded as safe for food contact, though thermal
