What is PSU Plastic Material

On the stage of high-performance engineering plastics, psu plastic material (polysulfone plastic) is widely used in electronic and electrical, automotive, medical and industrial systems due to its excellent heat resistance, dimensional stability and chemical resistance. The PSU 905 TFE 15 launched by Antep, through 30% glass fiber reinforcement + 15% PTFE filling + V-0 flame retardant modification, has achieved a balanced upgrade in mechanical, lubricating and flame retardant properties, making it an ideal material for high-demand applications.

01 | Material Core Advantages

Reinforced Structure

  ・30% glass fiber filling → flexural modulus 7584 MPa, tensile modulus 8964 MPa.

  ・Ensures the stability of complex structural components under long-term loads and high-temperature environments.

Lubricity

  ・15% PTFE modification significantly reduces the coefficient of friction.

  ・Suitable for high-friction parts such as gears, bearings and pump bodies, it can extend the service life.

Flame retardant safety

  ・It complies with UL94 V-0 (3.0mm) and meets the fire protection standards for electronic and electrical products.

  ・The synergistic effect of flame retardants and glass fibers does not sacrifice mechanical strength.

Heat resistance

  ・The heat distortion temperature is 182℃, and it can maintain stable performance during high-temperature operation.

Low shrinkage rate

  ・The shrinkage rate is only 0.10%, with high molding accuracy, reducing warpage and dimensional errors.
