An amorphous polymer with a high glass transition temperature and little moisture absorption, PPSU plastic. In addition, PPSU material outperforms PSU and PES from the polysulfone group in terms of impact strength and chemical resistance. In addition to these features, PPSU polymer is resistant to detergents and disinfectants and can tolerate sterilization with superheated steam better than other polymers in this group.
PPSU plastics offer:
- High operating temperature (180°C)
- Good chemical compatibility
- Excellent resistance to hydrolysis (suitable for repetitive steam sterilisation)
- High rigidity over a wide range of temperatures
- Very high impact strength
- High dimensional stability
- Very good resistance against high energy radiation (gamma and X-rays)
- Good electrical insulating properties
- Favourable dielectric characteristics
The Hegen Polyphenylsulfone (PPSU) line is constructed from material that complies with FDA regulations for food contact. Because to its great toughness and high temperature resistance, PPSU is frequently utilized in the production of medical appliances. It is lightweight, BPA-free, and combines the best qualities of both glass and plastic materials.
A thermoplastic material with a strong resistance to heat and impact is called PPSU. This makes it a very trustworthy and safe option for your baby’s feeding requirements.
