Polyethylene Terephthalate (PET)

Polyethylene Terephthalate (PET) – High-Performance Polymer for Bottles, Fibers & Packaging

Polyethylene Terephthalate (PET) is a semi-crystalline thermoplastic polymer widely used in beverage bottles, food packaging, polyester fibers, and engineering components. Known for its exceptional strength, clarity, chemical resistance, and recyclability, PET is one of the most in-demand plastics in the global packaging and textile industries.

PET is available in Amorphous PET (A-PET) for transparent packaging and Crystalline PET (C-PET) for heat-resistant and structural applications, making it a versatile polymer for multiple industrial sectors.
