What is Polyethersulfone Material - BASF 3010 P MR

Under extreme working conditions of high temperature, high pressure and high corrosion, whether the material can stand the test of time is more crucial than the parameters. PESU 3010 MR, as a high-viscosity polyethersulfone launched by BASF, not only possesses core advantages such as stress crack resistance, high toughness, and thermal stability, but is also highly suitable for application scenarios with extremely high reliability requirements, including medical, electrical, and industrial fields.

We will guide you to quickly understand the technical value of this polyethersulfone material and tell you why choosing an experienced material trader is far more efficient and worry-free than directly contacting a brand.

01 | Material Introduction: Non-enhanced high-viscosity PESU, breaking the boundaries of traditional formulations

PESU 3010 MR Is a non-reinforced high-viscosity polyethersulfone material with a flame retardant grade of UL94 V-0, and it has the following core properties:

  ・Non-reinforced design: No addition of glass fiber, yet achieving high toughness and good dimensional stability;

  ・High stress crack resistance: Effectively resizes the propagation of microcracks caused by stress concentration during long-term use.

  ・Excellent chemical stability: It has outstanding resistance to acids, alkalis, organic solvents, etc.

  ・Dual processing method compatibility: Suitable for both injection molding and extrusion processes simultaneously.

This material structure design concept offers a new solution for manufacturers who pursue high toughness and chemical resistance applications without reinforcement.

02 Thermal, mechanical and electrical performance, suitable for multi-industry demanding applications.

In the actual performance test, PESU 3010 MR Demonstrated an all-round excellent performance:

The mechanical properties are balanced, with both toughness and rigidity coexisting

  ・The tensile modulus is 2650 MPa, which is sufficient to meet the rigidity requirements of most structural components.
  ・The tensile strength is 85 MPa, ensuring the structural integrity of the product during use.
  ・The notched impact strength (from -30°C to 23°C) is 8.0 kJ/m², demonstrating its excellent low-temperature toughness.
  ・The notch-free impact value of the NB grade simply supported beam indicates that the material has an extremely high fracture energy and almost no brittle cracking occurs.

It has strong thermal stability and excellent high-temperature resistance

  ・The heat distortion temperature (HDT) reaches 207°C, maintaining structural stability in high-temperature environments.
  ・The coefficient of linear expansion is only 5.2E-5 cm/cm/°C, which is significantly better than most engineering plastics and has strong dimensional stability.

Outstanding electrical insulation performance

  ・The volume resistance and surface resistance are both in the 10¹⁵ Ω grade, suitable for high insulation requirements.
  ・The insulation strength is as high as 34 kV/mm, making it safe and reliable in high-voltage environments.
  ・With a stable dielectric constant (3.80-3.90), it can be widely used in the packaging or isolation of electronic components.
