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


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 chemical structure

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.

PPSU raw material manufacturers overview

PPSU materials are mainly produced by Solvay (Solvay), BASF, Sumitomo Chemical, Youju New Materials, Shandong Special Plastics, Shandong Jinlan Special Plastics etc. The following is a brief introduction of these manufacturers.

Solvay (Solvay)

Solvay is a world-leading chemical group and a provider of ultra-high-performance polymer/performance polymer integrated solutions. In the aerospace, automotive, chemical, consumer electronics, medical and other industries, Solvay offers a full range of ultra-high/high performance polymer materials such as PAEK, PEEK, PAI, PPSU, LCP, PPA. Solvay is a new supplier of plastic materials for smoking fixtures, providing PEEK for the heating pad base and PPSU for the outer casing. Solvay has been working in the international and domestic e-cigarette industry for a long time. At present, it has close interaction and in-depth cooperation with many well-known electronic cigarette manufacturers and has accumulated a large number of material application solutions.


BASF is the world's largest chemical company and was named "the most admired chemical company in the world" by the US business magazine Fortune. At the same time, BASF ranked second among the cross-industry comparisons of all German companies. BASF is one of the first manufacturers to promote PPSU materials on antenna nano-injection of Apple series mobile phones.
