Polyethylene terephthalate does not affect human health. While many consumers have erroneous assumptions about PET, it does not contain BPA, phthalates, dioxins, cadmium, lead, or endocrine disruptors. Therefore, drinking water from a polyethylene terephthalate bottle that has been left in a hot car, frozen, or washed and used more than once, does not pose any health risk.
Polyethylene Terephthalate is not considered toxic. Heat treatment of recycled PET flakes removes any volatiles, making them safe and meeting the requirements for direct food contact.
According to the ILIS study, PET is biologically inert if ingested, is dermally safe during handling, and is not a hazard if inhaled. In addition, no evidence of toxicity has been detected in feeding studies using animals. The study states, “Similar studies conducted with monomers and typical PET intermediates also show that these materials are essentially non-toxic and pose no threats to human health.”
Additionally, PET bottles and containers that are discarded in landfills pose no risk of harm or leaching. Because it is inert, it is resistant to attack by micro-organisms and won't biologically degrade. PET bottles can also easily be crushed flat to take up relatively little landfill space.
HDPE and PET are both very popular for manufacturing bottles. They are quite similar on the surface but do have some differences that set them apart.
High-density polyethylene (HDPE) is a ubiquitous plastic used in manufacturing. HDPE can withstand temperatures ranging from -110° to 165° F. Unlike PET, HDPE is not clear but can be used to make semi-opaque bottles.
Polyethylene terephthalate isn’t as temperature-resilient as HDPE. PET does protect against diluted acids, oils, and alcohols that attack HDPE. Like HDPE, PET can be matched to any color.
Yes, polyethylene terephthalate is suitable for 3D printing. PET 3D filament is an easy material to use. Its temperature range for the PET extruder is quite wide at 160°C to 210°C. The advantages of using PET for 3D printing are that it is food-safe, waterproof, has a glass-like appearance, and does not produce odor or fumes. The disadvantages are that PET may take some tweaking to find the right temperature for printing. In addition, it has a wide range of printing temperatures and may be slow to print.
