What is PES Material - BASF 2010 HC

As polysulfone materials (PES materials) continue to move towards high functionality and high reliability, how to achieve the unity of transparency, flame retardancy and high cleanliness level compatibility while maintaining thermal stability and mechanical strength has become a key issue in material selection in the high-end manufacturing field.

BASF's PESU 2010 HC, as a medium-viscosity, non-reinforced transparent polyethersulfone material, provides a powerful solution for such needs.

01 | From "transparent" to "reliable": PES material innovation is not limited to high temperature resistance

Traditionally, PESU is considered a typical high-temperature engineering plastic, known for its excellent heat deformation temperature (HDT), drug resistance, and mechanical strength, but often inferior to PC or COP in terms of optical transparency and aesthetics.

The difference of PESU 2010 HC is:

  ・88% light transmittance (DIN 5036), which brings new options for visual identification parts such as medical and electrical;

  ・The medium viscosity design takes into account both molding fluidity and structural strength, and is suitable for complex geometric structure molds;

  ・Naturally transparent + flame retardant V-0, no need to add colored flame retardants, meeting the dual requirements of visual clarity and safety.

This makes it the first choice for market segments that require simultaneous optical performance + heat resistance + flame retardancy, such as medical-grade equipment, transparent electrical housings, and instrument window covers.

02 | Performance Interpretation: Thermal stability at the structural component level + electrical safety

From the data, PESU 2010 HC is not just a "transparent material", its comprehensive performance fully meets the requirements of industrial-grade structural components:

Outstanding thermal stability:

  ・HDT reaches 205°C, long-term use temperature is up to 180°C (IEC 60216), and short-term resistance can reach 220°C;
  ・Glass transition temperature is 225°C, dimensional stability after molding is strong, and anti-warping ability is better than most transparent materials;
  ・Linear expansion coefficient is only 5.2E-5, suitable for a variety of precision assembly requirements.

Excellent electrical performance:

  ・Insulation strength is 35 kV/mm, which can be used for transparent components under high voltage;
  ・Volume resistance and surface resistance reach 10¹⁵ Ω level, and can still maintain electrical isolation in humid or corrosive environments;
  ・CTI value reaches 100V, which meets the basic requirements of the electronic field for material breakdown path.

These properties enable PESU 2010 HC to form a differentiated competitive advantage in the fields of optics, electrical and instrumentation, and it is an industrial-grade material that is "transparent but not fragile".

03 | Popular application trends: high cleanliness, high recognition, and structural transparency

Currently, many high-value-added manufacturing industries are accelerating the "visual transparency" of structural parts to improve safety, convenience and user experience.

The following are the popular application trends of PESU 2010 HC:

Medical equipment visual components

  ・Applicable to visual areas such as hemodialysis, infusion pumps, and air sensor housings;
  ・The material itself is BPA-free and does not require the addition of color powder, meeting the non-toxic requirements;
  ・It has strong resistance to high-temperature steam sterilization and does not turn yellow or deform after repeated use.

High-end electronic and industrial detection windows

  ・Used for multi-functional transparent housings, measuring equipment windows, and laser instrument covers;
  ・Ensure electrical safety and mechanical strength while taking into account appearance aesthetics.

Aerospace transparent components

  ・Applicable to control windows and cover components in high-temperature and high-pressure environments;
  ・Under the requirements of lightweight and safety, it can replace glass or traditional PC materials.

04 | PES material procurement trends: Why choose professional traders instead of looking for brand manufacturers directly?

Although PESU 2010 HC comes from BASF, for end customers, simply "looking for a brand" is often far from enough.As a supplier focusing on high-performance engineering plastics trade for 24 years, we have observed the following procurement trends emerging:

  ・Material selection needs tend to be small batches, multiple types, and refined, while brand manufacturers focus more on standardized bulk supply;

  ・Multi-material comparison and application suggestions have become a rigid demand in the early stages of R&D, and traders can horizontally integrate multiple alternative models (such as PEI, PPSU, etc.);

  ・Response speed and delivery flexibility determine the pace of trial production, and high-quality traders can flexibly allocate resources and quickly deliver samples according to the development progress;

  ・Sustainability and compliance reviews are tightened, and suppliers need to provide multiple document support and traceability guarantees such as RoHS, REACH, FDA, and USP.
