PPSU

PPSU stands for Polyphenylsulfone, a type of high-performance thermoplastic known for its superior durability, heat resistance, and chemical stability. PPSU materials are widely chosen for baby bottles due to their ability to withstand repeated sterilization processes without deforming or releasing harmful substances. This material does not absorb odors or colors and is BPA-free, making it a safe choice for infant feeding equipment.
