Polyethersulfone, PES or PESU, is an amorphous and pale amber high-performance thermoplastic that has good transparency and inherently flame resistance, and it is one of the lowest smoke-emitting materials available. PES is known for its dimensional stability at high temperatures in both air and water. It also has good electrical properties, chemical resistance.
- Outstanding Creep Resistance up to 150°C in the long term.
- Good Chemical Resistance：Highly resistant to acids, alkalis, oils, greases, and aliphatic hydrocarbons and alcohols…
- Good Optical Clarity
- Very Good Hydrolytic & Sterilization Resistance
- Excellent Electrical Insulation Properties
- Outstanding Rigidity even at high temperatures.
