Application

  • Medical Device Housings: MRI-safe equipment casings, ventilator components.
  • Surgical Instruments: Transparent scalpel handles, forceps.
  • Diagnostic & Fluid Management: Blood filters, IV connectors, dialysis parts.
  • Implantable Prototyping: Biocompatible trial components.

Features & Benefits

Radiation-Resistant Sterilization

It withstands high-energy radiation (e.g., gamma/E-beam) without degradation, ideal for reusable surgical tools or implantable devices requiring repeated sterilization cycles.

Biocompatibility Assurance

It meets ISO 10993-1 standards for bodily contact, reducing regulatory hurdles for IV connectors, dialysis housings, and diagnostic equipment.

High Lipid & Chemical Resistance

It resists oils, lipids, and cleaning agents, preventing cracks or cloudiness in fluid-handling parts like transfusion chambers or drug delivery systems.
