Biberón Hegen PPSU de 8 oz/240 ml en paquete de 2 unidades

The bottle body is PPSU molded from Solvay's Duradex polyphenylsulfone, with the resin house naming Hegen's PCTO bottles as the application, so the resin source is on record rather than an unattributed "premium plastic". One review team took delivery of the bottle, used it and reported the same PPSU construction; there is no polycarbonate or unspecified plastic in the bottle body.

The bottle body is polyphenylsulfone (PPSU) and the finished bottle is free of BPA, BPS and phthalates — the bisphenol scope goes beyond a bare BPA-free line and names the replacement compound. The Duradex PPSU grade it is molded from is a high-purity food-contact polymer free of artificial pigments, phthalates and bisphenols; BPF is not addressed, and no migration testing is published for the assembled bottle.

The bottle carries graduated volume markings on its exterior and is sold in white, pink, blue and purple colourways, and nothing is published about lead in those printed or pigmented surfaces — no XRF result, no accredited-lab lead figure, and no statement that the markings are molded rather than applied. The base resin itself is free of artificial pigments, which speaks to the polymer and not to the exterior markings.

The PPSU used here is rated from -20°C to 180°C and qualified for more than 1,000 steam or hot-water sterilization and dishwasher cycles without loss of toughness, so sterilization compatibility is stated in concrete terms. What is missing is the other half: no replacement interval is given for the bottle or nipple, and no particle-shedding or migration data at sterilization or feeding temperature is published for this bottle.

Each two-pack includes two medium-flow nipples for babies 3 months and older, but the nipple polymer is never named — no silicone grade, no latex disclosure, no post-cure or residual statement. The BPA, BPS and phthalate-free bullet is the only chemistry line offered, and it does not identify what the nipple is made of.

We queried the full CPSC recall corpus — 9,944 records spanning June 1973 to August 2026 — and Hegen USA appears nowhere in it, in any role, at any date. The same corpus returns hits for comparable juvenile-product classes such as pacifiers, cribs and strollers, so the clean result reflects the brand's absence rather than a query that missed.

A replacement interval is published for the bottle: every 3-6 months, or sooner if cracks, chips or other visible wear appear. This falls short of the criterion's ask because the interval is generic rather than corroborated by an outside source, no separate cadence is given for the nipples, and the specific visible degradation signals beyond cracks and chips (cloudiness, stickiness) are not spelled out for this product.

The bottles are molded from Solvay's Duradex PPSU, whose circular non-fossil feedstock content is third-party mass-balance certified under ISCC PLUS — a certification of the resin supply chain, not a safety certification of the finished bottle. For the bottle itself, the only published statement is a BPA, BPS and phthalate-free bullet, with no named standard, test lab or certificate reference beside it.

Material disclosure stops short: the bottle body is named as PPSU, but the country of manufacture, the nipple and collar materials and the manufacturing site are not published.
