In response to strong customer demand, Solvay has added Veradel® HC A-301 polyethersulfone (PESU) to its portfolio of high-performance healthcare polymers. The medical-grade polymer retains transparency and stiffness at high temperatures and offers processing advantages over other commercial high-heat, transparent polymers. Veradel® HC A-301 PESU has been tested under ISO 10993 biocompatibility standards and a Master Access File (MAF) is on record with the U.S. Food and Drug Administration (FDA). The material is expected to pass USP Class VI testing. These well-documented compliance records can facilitate the design and regulatory application process for medical device OEMs, thereby accelerating product time to market.

Veradel® HC A-301 PESU retains its transparency and toughness at high temperatures and offers processing advantages over other commercial transparent polymers.

Typical Applications

  • Housings and internal structural components for medical diagnostic equipment
  • Monitoring and filtration equipment
  • Biopharma processing applications such as sight windows and quick-connects

Alternative to PEI

Veradel® HC A-301 PESU exhibits properties similar to those of polyetherimide (PEI) for strength, stiffness, transparency, dimensional stability, and inherent flame resistance as well as compatibility with steam sterilization and chemical sterilants.
