Engineering Plastic PSU Natural Sheet

Availability:
Quantity:

JUTAIPSU®NA, a Polysulfone (PSU) Natural Sheet, is a high-performance, transparent engineering plastic known for its exceptional chemical resistance, thermal stability, and rigidity. Due to its unique molecular structure, PSU offers superior mechanical properties, resistance to various environmental conditions, and excellent dielectric performance. These characteristics make PSU an ideal choice for industries requiring materials that can withstand harsh environments and demanding operational conditions.


JUTAI offers large size PSU sheet, 1250mm width & 3M length; and 6mm thin PSU sheets.

Key Features of Engineering Plastic PSU Natural Sheet:


High Tensile Strength

Tensile Strength above 75 MPa, ensuring that the material can handle significant mechanical stress without failure. This makes it suitable for use in structural applications where strength is essential.


High Flexural Strength

Flexural Strength above 100 MPa, offering excellent resistance to bending and deformation, which is crucial for components subjected to flexural loads.


Excellent Thermal Load Capacity

The Heat Distortion Temperature is 174°C, indicating that PSU maintains its shape and strength under moderate to high temperatures, making it ideal for applications in environments exposed to heat.


Superior Flame Resistance

PSU has outstanding flame resistance and arc resistance, providing additional safety in applications where fire hazards are a concern.


Excellent Dielectric Properties

With excellent dielectric properties, PSU is an ideal material for insulation and electrical applications where minimal electrical conductivity is required.


Outstanding Dimensional Stability

PSU features excellent dimensional stability and a low coefficient of thermal expansion, ensuring that components made from this material maintain their shape and size even under temperature variations.


High Heat Resistance

Suitable for long-term use at up to 160°C, PSU remains stable and functional at elevated temperatures, making it ideal for applications that involve consistent exposure to heat.


Excellent Chemical Resistance

PSU exhibits high resistance to a wide range of acids, saline solutions, detergents, hot water, and steam, providing excellent durability in demanding environments where chemical exposure is common.


Outstanding Radiation Resistance

The material's resistance to radiation ensures that it remains stable and retains its properties in environments exposed to radiation, making it suitable for applications in medical and other radiation-sensitive industries.


Low Ionic Impurity Levels

PSU has low ionic impurity levels, which is especially important in industries like electronics, where the presence of ionic impurities can interfere with the functioning of sensitive components.



Food and Beverage Industry


Its resistance to hot water and steam makes it suitable for use in food processing and food packaging equipment that requires consistent performance under high temperatures and moisture conditions.


New industry/ Hydrogen electrolyzer Bipolar Plates



High performance plastics(PSU for AWE, PEI/PEEK/PPS for PEM ) are gradually replacing metals of bipolar frame in Hydrogen electrolyzer. Due to their corrosion resistance, lightweight properties, extended service life, excellent electrical insulation, and greater design flexibility.
