What is ColorRx® PSU-1000RX

ColorRx® PSU-1000RX is a medical-grade polysulfone (PSU) particle launched by Americhem, specifically designed for medical care and related precision applications. This material not only possesses the consistent heat resistance and hydrolysis resistance of polysulfone resin, but also has passed the biocompatibility certification, making it safe for use in medical devices and care products.

01 | Material Properties

Medical-grade certification: Complies with the safety and biocompatibility standards required for medical devices.

High-temperature resistance: The heat deflection temperature can reach up to 345℉ (approximately 174℃), maintaining stable performance in high-temperature environments.

Mechanical stability: Tensile strength of 10,000 psi, flexural modulus of 390,000 psi, balancing toughness and rigidity.

Chemical and hydrolytic stability: Water absorption rate as low as 0.30%, suitable for long-term contact with cleaning agents and disinfectants.

Flexible processing: Melt index 6.5g /10min (300℃/1.2kg), supports injection molding, which is conducive to efficient production.

02 | Typical Uses

ColorRx® PSU-1000RX is widely used in:

  ・Medical care supplies: infusion instruments, dialysis equipment shells, monitor accessories.

  ・Reusable sterilizable components: high-pressure steam sterilization handles, medical operation components.

  ・High-temperature nursing equipment: ventilator components, operating room instrument casings.

03 | Process compatibility

Método de procesamiento: Injection molding, with good fluidity, suitable for complex thin-walled parts.

Suggested forming parameters: The barrel temperature should be around 300℃, and the mold temperature should be controlled within 150℃ to ensure the stability of appearance and dimensions.

Post-treatment: To ensure performance, it is recommended to dry it moderately before use to avoid moisture causing bubbles or a decline in mechanical properties.
