What is PESU Polymer

PESU 2010 MR is a polyethersulfone (PESU polymer) material for injection molding launched by BASF. It is favored by customers in the electronics, industrial equipment and structural parts industries for its strong dimensional stability, excellent fluidity and outstanding high temperature resistance.

As a supplier of plastic raw materials, we can provide original particles, sample testing, parameter information and related selection suggestions for customers with processing, modification and terminal injection molding needs.

01 | Core characteristics: not just high heat resistance

Starting from the material properties and combining actual test data, we analyze the outstanding performance of PESU 2010 MR in multiple key dimensions:

✅ Excellent dimensional stability

  ・The linear expansion coefficient is only 5.2E-5 cm/cm/°C, which is much lower than most engineering plastics, ensuring the precise shape of parts in high temperature environments;

  ・The shrinkage rate is small (0.82% in the flow direction and 0.86% in the vertical direction), which is particularly friendly to precision parts and insert structures with high tolerance requirements;

  ・Even in multiple thermal cycle environments, it can maintain structural stability and reduce deformation.

✅ Good fluidity and friendly processing

  ・The melt index is 70 cm³/10min, which is a medium to high flow level, which is conducive to the injection molding of complex structures and thin-walled parts;

  ・High molding efficiency, suitable for mass production scenarios that are sensitive to beats (such as plugs, precision modules, snap-on structures, etc.);

  ・No special mold structure is required, conventional injection molding equipment can be used for stable production.

✅ Strong thermal performance, adaptable to high temperature conditions

  ・The heat deformation temperature is as high as 205°C (ISO 75), and it can withstand continuous heat source or current heating;

  ・Pesu polymer can be used in high temperature load areas such as engine compartment interior, control module, electrical connection box, etc.;

  ・It still has good thermal deformation control ability without annealing conditions.

✅ Excellent electrical performance, suitable for high insulation applications

  ・Volume/surface resistance up to 10¹⁵ Ω, insulation strength 37 kV/mm;

  ・Stable dielectric constant (3.8 @1MHz) + low dissipation factor, suitable for RF/high frequency environment;

  ・Can be used for micro-electric devices, control modules, relay bases and other parts that are sensitive to leakage and creepage.

02 | Typical application direction of pesu polymer: serving high temperature and high precision requirements

03 | PESU Polymer Technical Highlights

04 | Regulatory and testing compliance: flame retardant and safety standards for global markets

  ・UL94 V-0 (1.5mm & 3.0mm) certification meets the mandatory fire protection standards for electronic and electrical components;

  ・Water absorption data is divided into saturation (2.2%) and equilibrium (0.80%). It is recommended to fully dry before molding to ensure stable electrical performance;

  ・CTI value is 100V, which can meet the basic anti-tracking requirements of industrial control cabinets and transformer structural components.

05 | Frequently Asked Questions (FAQ)

Q1: Is this model suitable for high-temperature and complex electronic components?

A: Absolutely suitable. It has high heat deformation temperature and good fluidity, and performs well in dimensional control and assembly.

Q2: Can it be used for modification processing?

A: Yes. PESU 2010 MR is a non-reinforced material, suitable as a flame retardant substrate, viscosity adjustment resin, compounding additive and other material solutions.

Q3: Does the mold need special treatment?

A: No. It is recommended to use high temperature resistant mold steel (such as S136, H13), and keep the mold temperature above 130°C to obtain better surface quality and dimensional control.

Q4: Is the material available in stock? Can I request a sample?

A: Yes, as a 24-year professional plastic raw material supplier, Juyuan has a stable supply channel and can provide sample testing, small batch delivery, parameter data package and other supporting services.
