What is TECASON™ S Polysulfone

 

When engineers and designers look for materials that can handle heat, mechanical stress, and electrical insulation, TECASON™ S Polysulfone (PSU) often comes up as a reliable choice. In our experience, buyers appreciate it for injection molding, especially when complex geometries, high-precision parts, or critical structural components are involved. It’s used widely in electronics, high-temperature piping, medical devices, and other demanding applications.

TECASON™ S Polysulfone

 

01 | Core Advantages

 

Heat resistance and dimensional stability

TECASON™ S Polysulfone keeps its shape even under medium- and high-temperature conditions. Its heat deflection temperature reaches up to 181°C (0.45 MPa), and the low linear expansion coefficient of 5.6E-4 cm/cm/°C helps reduce warpage. Many engineers note that this makes designing complex molds much less stressful.

Reliable mechanical properties

With a tensile strength of 70.3 MPa, flexural strength of 106 MPa, and elongation of 100%, it provides a nice balance of stiffness and toughness. The Izod notched impact strength of 69.4 J/m means it can handle complex stresses. You might notice that even thin-walled parts or high-load components perform consistently when molded with this material.

Electrical insulation

Its dielectric constant is 3.1, volume resistivity 5E16 Ω·cm, and dielectric strength 16.7 kV/mm. This makes TECASON™ S ideal for high-voltage electronic parts such as switches, relays, and connectors. In practice, the low dissipation factor (0.001) ensures long-term stable operation, which is something our clients often highlight.

Processability and molding efficiency

Granular form, friction coefficient of 0.37, and Rockwell hardness of R120 allow high-precision injection molding. Many designers tell us that this combination reduces defects and improves production efficiency.

Resistencia química

It stands up to a wide range of chemicals, making it suitable for lab equipment, medical devices, and chemical pipelines. In some cases, clients have reported years of trouble-free operation in harsh chemical environments.

 

02 | Industry Applications

 

Medical equipment – Syringes, filters, dialyzers, and lab devices that need repeated sterilization and high-temperature resistance.

Electronics and electrical – Ideal for insulating switches, connectors, and relay housings.

Aerospace and automotive – Pipes, valves, and structural components that must endure extreme temperatures and mechanical stress.

New energy applications – Electric vehicles, charging stations, and high-temperature electrical systems.

Sostenibilidad – Recyclable and reusable, aligning with green manufacturing trends. Many engineers appreciate that it fits modern environmental standards.

 

03 | Practical Recommendations

 

Complex geometries – Works well for thin-walled or intricate parts. Proper mold design is key to reducing shrinkage and warpage.

Electronic insulation – Low dielectric constant and high resistivity make it reliable for high-voltage parts.

Medical and lab equipment – Excellent resistance to repeated sterilization.

High-temperature piping and valves – Chemically resistant, suitable for continuous high-temperature operation.
