polyethylene terephthalate

polymer

Polyethylene terephthalate (PET) is a thermoplastic polyester widely used for its combination of mechanical strength, chemical resistance, and ease of processing. It is the dominant material for beverage bottles, food containers, and flexible packaging due to its clarity, lightweight nature, and recyclability, while also serving demanding applications in textiles, automotive components, and electrical insulation where its stiffness and thermal stability are advantageous. Engineers select PET when balancing cost-effectiveness with reliable performance in semi-structural applications, though its lower service temperature and moisture sensitivity compared to engineering plastics like polycarbonate or nylon require careful consideration in high-heat or high-humidity environments.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
