网页2024年8月16日 · polyethylene terephthalate (PET or PETE), a strong, stiff synthetic fibre and resin and a member of the polyester family of polymers. PET is spun into fibres for permanent-press fabrics and blow-molded into disposable beverage bottles. PET is produced by the polymerization of ethylene glycol and terephthalic acid.
Polyethylene terephthalate - Wikipedia
网页Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.

网页Polyethylene Terephthalate Structure. In acidic medium, protonation of terephthalic acid occurs that reacts with ethylene glycol to form an intermediate which rearranges and with the transfer of OH- ions, forms polyethene terephthalate polymer. Overall both monomer units are joined together with ester linkage, therefore commonly called polyester.

网页Polyethylene terephthalate (PET or PETE) is a general-purpose linear semicrystalline thermoplastic polymer. It belongs to the polyester family of polymers. These resins are known for their excellent combination of properties. These properties include mechanical, thermal, and chemical resistance as well as dimensional stability.
Polyethylene terephthalate | Formula, Properties & Application
网页Chemical Structure. The chemical structure of PET consists of repeating units of a group containing one ethylene glycol molecule and one terephthalic acid molecule. These two molecules react through a condensation polymerization process, resulting in the formation of PET and the release of a water molecule. Chemical formula: (C 10 H 8 O 4) n
