Features & Benefits

Sustainable Medical Compliance

This ISCC PLUS-certified resin uses bio-circular raw materials via mass balance, reducing carbon footprint while meeting strict medical safety standards (ISO 10993-1). Buyers gain eco-compliance without sacrificing performance.

Unmatched Sterilization Durability

It withstands high-energy radiation, steam (121°C), and ETO sterilization without degradation. Ensures longevity for reusable medical devices, cutting replacement costs.

High Chemical & Impact Resistance

Exceptional lipid/oil resistance (puncture energy: 70J at -30°C) and transparency. Ideal for surgical tools, lab equipment, and transparent housings exposed to harsh fluids.
