PET

polymer

PET (polyethylene terephthalate) is a thermoplastic polyester widely used across consumer and industrial applications due to its excellent clarity, chemical resistance, and processability. It is the dominant material for single-use beverage containers, food packaging films, and textile fibers, and also serves in demanding applications including automotive components, electrical insulation, and engineering parts where moderate strength and good dimensional stability are required. Engineers select PET for its favorable balance of optical properties, moisture barrier performance, and cost-effectiveness, though its use at elevated temperatures is limited compared to higher-performance engineering polymers.

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.
