What is PESU Polymer

As advanced manufacturing continues to pursue high-temperature stability, structural strength and long-term reliability, PESU polymer (polyethersulfone) is gradually moving out of laboratory and aerospace-grade applications and into more automotive, electrical and precision industrial fields. Among them, Dimension E0510 G9 SW 10112 launched by BASF, as a 45% glass fiber reinforced PESU material, has excellent performance in heat resistance, mechanical properties, electrical insulation and other aspects, and is becoming a high-end option that has attracted much attention in the engineering plastics market.

1. The technical core of PESU Polymer: Why does the industry choose it?

PESU (Polyethersulfone) is a high-temperature polyarylether thermoplastic, which belongs to the "super engineering plastics" category with PPSU, PEEK and other materials. Its molecular structure is highly rigid and resistant to oxidation, giving it the following characteristics:

  ・Excellent thermal stability: heat deformation temperature can reach 210°C, melting temperature is as high as 340~390°C, and it can be used for a long time in high temperature environment;

  ・Excellent dimensional stability: linear expansion coefficient is as low as 1.25E-5 cm/cm/°C, which is conducive to precise processing and matching;

  ・Excellent electrical performance: CTI value reaches 125V, meeting the needs of demanding electrical isolation scenarios;

  ・Excellent chemical and hydrolytic stability: tolerant to most polar solvents and hot water.

2. In-depth E0510 G9: Using data to tell the dual balance of strength and toughness

Compared with conventional PESU polymer material, the biggest difference of E0510 G9 is its glass fiber reinforcement ratio (GF45) of up to 45%. This formula brings not only an increase in strength, but also a further evolution of structural design:

It is particularly worth mentioning that its impact performance at low temperature (-30°C) is still stable, suitable for components operating in extremely cold environments, such as electrical connectors and aviation interior parts in high latitudes.

Electric vehicles and electronic connection systems

Against the backdrop of the accelerated development of new energy vehicles, the demand for heat-resistant electrical insulation materials is growing rapidly. With its high CTI value and excellent dimensional stability, E0510 G9 is very suitable for high-voltage connector housings, sensor housings, electronic control module brackets, etc.

Industrial automation equipment

E0510 G9 can operate continuously under high temperature and high load conditions, and is especially suitable for high-frequency mechanical fixtures, transmission components and motor housings, meeting the trend of "long life + maintenance-free" in industrial automation.

Medical and analytical instruments

Although this model does not specifically emphasize biocompatibility, PESU has a broad foundation as a medical material, and the mechanical and thermal properties of E0510 G9 are also suitable for structural support components of precision medical equipment.

04 | Comparative advantages with other high-performance polymers

In actual selection, PESU often competes with PPSU, PEEK, PAI and other materials. The following is a comparative analysis of E0510 G9:

PESU E0510 G9 has outstanding performance in cost-effectiveness and multi-performance balance. It is an "efficient choice" without sacrificing structural strength and thermal stability.

05 | Technical processing suggestions and precautions

Injection temperature setting: It is recommended to control the mold temperature at 160180°C and the barrel temperature at 360390°C to avoid uneven distribution of glass fiber due to insufficient temperature;

Screw shear control: Control the medium shear rate to reduce material degradation;

Demolding treatment: For high-density materials, attention should be paid to mold exhaust and demolding slope design.
