What is PPSU Material?

PPSU (Polyphenylsulfone) is a high-performance engineering plastic. It is widely used in medical, aviation, new energy, electronics and other industries due to its excellent high temperature resistance, chemical corrosion resistance, mechanical strength and biocompatibility.

Behind the question of "what is PPSU material" is the profound global demand for material performance, sustainability and supply security.

For engineers, technology purchasers and brand manufacturers engaged in raw material selection, 2025 is the key node to re-examine the value and supply layout of PPSU.

01 | Analysis of the core characteristics of PPSU: structure empowers high performance

The high performance of PPSU comes from the stable structure of benzene ring and sulfone group (–SO₂–) in its molecular structure, which gives it a series of unique advantages:

  ・Strong high temperature resistance: The glass transition temperature is as high as 220°C, which is suitable for high-pressure steam sterilization and long-term high temperature use (180°C).

  ・Excellent chemical stability: resistant to a variety of strong acids, alcohols, disinfectants, suitable for medical equipment and industrial pipelines.

  ・Good mechanical toughness: high notch impact strength, stress cracking resistance, not easy to deform.

  ・Optical transparency: the basic color is amber translucent, which can be improved to nearly full transparency through modification.

  ・Regulatory compliance: FDA, EU 10/2011, ISO 10993 certified, widely used in baby products, surgical instruments, food contact parts.

02 | Technology Trends: What changes is PPSU undergoing in 2025?

✅ Bio-based PPSU is gradually landing

The bio-based PPSU jointly developed by Solvay and Sinopec has a carbon footprint 70% lower than traditional petroleum-based materials. Although the cost is high (premium of about 50%), it has strategic value under the CBAM carbon tariff trend.

✅ Localization breakthrough

Companies such as Kingfa Technology and Water Holdings have gradually broken the dependence on key monomers such as diphenol, achieved mass production of high-purity domestic PPSU, and improved supply security.

✅ Advanced molding: PPSU Impresión 3D

For example, BASF's UltraFuse® PPSU filament has been used in the printing of complex aerospace structural parts, and its thermal stability and interlayer bonding strength have been significantly improved.

03 | Application map expansion: What key scenarios is PPSU entering?

04 | Comparison of PPSU with other engineering plastics

PPSU is better than PEEK in terms of cost performance, and far exceeds PC in temperature resistance and chemical stability, so it has become a preferred material in the fields of medical, aerospace, etc.

05 | Market trends and corporate dynamics (latest data in 2025)

06 | Procurement advice: How to judge whether PPSU is suitable for your product?

  ・High requirements for thermal stability? PPSU can cope with high-temperature steam or hot air circulation environment.

  ・Involving frequent disinfection or strong acid and alkali? PPSU has a chemical tolerance far superior to PC and Pensilvania.

  ・Require biocompatibility or food contact certification? PPSU is the standard answer for medical/baby products.

  ・Have a dual demand for strength and transparency? PPSU can meet the requirements of transparent structural parts through modification.
