Features & Benefits

Biocompatible & Sterilization-Ready

Makrolon® 2558 meets ISO 10993-1 standards for bio-compatibility and endures repeated ETO/steam sterilization cycles. This ensures patient safety and reduces device replacement costs in hospitals.

Effortless Injection Molding

With medium viscosity and smooth mold release, it minimizes production delays and defects. Ideal for complex parts like surgical housings or IV connectors, cutting cycle times by 15-20%.

High Clarity & Durability

It delivers 88% light transmittance (3mm thickness) and >130% strain at break. Perfect for clear surgical instruments or impact-resistant casings that stay crack-free in cold environments (-30°C).
