The Material
Why PPSU matters.
Not all baby bottle plastics are the same. PPSU is an FDA-compliant thermoplastic commonly used for medical devices that require repeated high-temperature steam sterilization — the same class of material trusted for reusable hospital equipment. That stability is why Grosmimi builds every cup and bottle from it.

Compliant — used for medical devices requiring steam sterilization
BPA Free
Zero Bisphenol A in the material
392°F
Heat resistance — safe from -4°F to 392°F
Peer-reviewed research has measured microplastic release from baby bottles under heat. Findings show polypropylene (PP) bottles release substantially more particles than PPSU and other advanced materials. The directional finding that PPSU is more stable than PP under heat is consistent across studies.
