What is PES Polyethersulfone

In high-precision manufacturing fields such as electrical appliances, printing equipment, and industrial structural components, a composite requirement of "lightweight + high strength + thermal stability + flame retardancy and environmental protection" is put forward for materials. PESU 2010 G4, as a 20% glass fiber reinforced pes polyethersulfone material developed by BASF, is becoming an important force in the field of engineering plastics with its outstanding mechanical, electrical and thermal properties.

01 | Why is PESU 2010 G4 of greater strategic value in the current industry?

With the continuous enhancement of demands for high-temperature durability, high-frequency insulation, and structural reliability, materials are no longer merely "qualified in performance". They must meet the requirements of multi-dimensional working conditions for coordinated adaptation

  ・High rigidity and structural strength: tensile modulus up to 6900 MPa, tensile strength up to 130 MPa, suitable for load-bearing structural parts such as electrical components, brackets and housings;

  ・Excellent thermal stability: The heat distortion temperature can reach up to 222°C, and the long-term temperature resistance of RTI can be as high as 190°C, making it suitable for continuous high-temperature environments.

  ・Flame retardant grade V-0:1.5mm and 3.0mm thickness of UL94 V-0, no halogen environmental protection;

  ・Electrical safety and reliability: volume resistance 1E15Ω ·cm, CTI grade 125V, meet the insulation requirements of medium and high voltage electrical appliances;

  ・Strong dimensional stability: low shrinkage (0.36% in flow direction, 0.61% in lateral direction), suitable for parts with high precision requirements.

These advantages make the PESU 2010 G4 a reliable choice for printing equipment core components, electrical enclosures, industrial heat connectors and other scenarios.

02 | Typical Application Scenarios: Specifically designed for printing equipment and electrical structural components

PESU 2010 G4 is widely used in the following occasions:

  ・Printer components: including guide rails, gear brackets, support beams and other structural parts that require high rigidity and thermal stability;

  ・Electronic and electrical components: Suitable for long-term energized structures such as circuit breaker housings, terminal seats, and insulating bases;

  ・Industrial precision parts: They are also widely used in structural support or snap-fit components where dimensional stability is required.

Due to the material's excellent processability and low warpage characteristics, it is particularly suitable for batch injection molding, meeting the efficiency requirements of high-speed production lines.

03 | Processing and Usage Suggestions

  ・Recommended process: Injection molding. It is suggested that the mold temperature be controlled at 120-160°C and the melt temperature be around 360°C.

  ・Drying recommendation: drying at 120°C for at least 4 hours before molding to reduce the influence of water absorption;

  ・Mold design: due to the high strength of the material, the mold should have good wear resistance, and appropriately increase the demoulding slope;

  ・Post-processing application environment recommendation:Avoid long-term exposure to high humidity and strong acid environments. Although the material is heat-resistant, the water absorption rate is below 1.6% at saturation.
