Polyethylene Terephthalate (PET)

Condensation polyester used in beverage bottles and textile fibers, prized for clarity and recyclability.

Core Principles & Analysis

• Carries resin identification code 1 and is the most widely recycled plastic.
• Sold as polyester fiber under trade names such as Dacron and Terylene.
• Biaxial stretching during bottle blow-molding aligns polymer chains for strength and gas barrier.

Specifications & Metrics

• MONOMER: Ethylene glycol + terephthalic acid
