1. What is PPSU?

PPSU (Polyphenylsulfone) is a high-performance medical-grade plastic known for its exceptional strength, heat resistance, and safety. It’s commonly used in healthcare equipment — and now in top-tier baby bottles.

2. Why Are PPSU Baby Bottles More Expensive?

PPSU bottles are priced higher because of:

  • Medical-grade quality: PPSU is trusted in hospitals and surgical tools for its non-toxic, ultra-safe properties.
  • Exceptional heat resistance: Can withstand repeated sterilisation, boiling, and microwave heating — without warping or releasing harmful substances.
  • Superior durability: Unlike traditional plastics, PPSU doesn’t crack, discolour, or degrade over time.
  • Longer lifespan: PPSU bottles often last significantly longer than bottles made from PP, PES, or glass alternatives.
  • Premium clarity and finish: They retain their transparent, amber-toned appearance even after heavy use.

3. Is a PPSU Bottle Right for You?

If you’re looking for a bottle that can handle frequent sterilising, long-term use, and is made with the highest safety standards in mind, PPSU is a fantastic choice. Especially ideal for parents who:

  • Need to sterilise bottles often
  • Want a glass-like look without the weight or breakability
  • Prefer to invest once in a longer-lasting bottle
