About Polymer

Polyphenylsulfone (PPSU) is an amorphous high-performance thermoplastic with excellent heat resistance, impact strength, and sterilization durability. It is widely used in medical, food, and aerospace industries where durability, hygiene, and long service life are crucial.

USAGE
  • Medical: Reusable surgical tools, insulin pens, dental devices, sterilization trays.
  • Food and baby products: Bottles, containers, caps, and hot food preparation parts.
  • Aerospace: Flame-resistant, lightweight cabin and system components.
  • Industrial: Valves, handles, pipes, and parts exposed to heat, steam, or aggressive cleaning agents.

PPSU is one of the most durable high-performance polymers for environments requiring repeated sterilization, mechanical endurance, and long-term stability.

ADVANTAGES
  • Excellent heat resistance: Withstands continuous use at ~180 °C and hundreds of autoclave cycles.
  • High impact strength: Remains tough even at low temperatures, ensuring safety in demanding environments.
  • Hydrolytic stability: Maintains integrity in contact with water, steam, or moisture.
  • Chemical resistance: Tolerates cleaners, disinfectants, acids, and aggressive substances.
  • Flame-retardant and biocompatible: UL94 V-0 rated and safe for medical and food contact.
WEAKNESSES
  • High cost: Significantly more expensive than conventional engineering plastics.
  • UV sensitivity: Degrades under sunlight unless stabilized.
  • Challenging processing: Requires high processing temperatures (over 350 °C) and careful drying.
