Applications of PPSU (polyphenylene sulfone), the superstar material in the E-cig industry


PPSU polyphenylene sulfone resin is one of the products of polysulfones (abbreviated as PSF series) and is a novel amorphous thermoplastic engineering plastic.

PPSU material characteristics advantages:

 
  • Light weight and high strength.
  • Extremely high toughness (also suitable for low temperature conditions), it can retain its great notched impact toughness at high temperature.
  • High heat resistance, no deformation, long-term service temperature 180°
  • Extremely high chemical stability
  • High resistance to X-ray and infrared
  • It can be repeatedly sterilized and can be in contact with water for a long time. It has been proved by experiments that even if it is immersed in hot water at 90 °C for 1 year, the mechanical properties of PPSU will not change.
  • Combining a variety of chemical and physical properties, PPSU materials are situated at the high level of the polymer performance pyramid.

PPSU applications are divided into the following three groups

 

Bottle/drinking bottle

 
PPSU is a high-end bottle/drinking bottle in daily life. PPSU does not contain bisphenol A and is resistant to high temperatures of 180 degrees. It combines the safety of glass bottles with the lightness and resistance of PP bottles. It can be used for a long time with hot water. Contact without deformation and release no toxic substances.

The upper cover of the Philip Morris International IQOS heater is made of PPSU modified material, which can meet the strength requirements during plug & unplug and improve the positioning accuracy when closing the cover. As a safe material commonly used in baby bottles, PPSU can be placed on the IQOS heater to meet the non-toxic requirement under heat. At the same time, the PPSU material is tough, aesthetically looks good, and the touch feeling is great.
