Veradel® HC PESU
Solvay Expands Offering for Healthcare Polymers
In response to strong customer demand, Solvay added Veradel® HC A-301 polyethersulfone (PESU) to its portfolio of high-performance healthcare polymers. It is the industry’s first PESU polymer to offer an FDA Master Access File (MAF) for medical devices.
Veradel® HC A-301 PESU retains its transparency and toughness at high temperatures and offers processing advantages over other commercial transparent polymers.
- Housings and internal structural components for medical diagnostic equipment
- Monitoring and filtration equipment
- Biopharma processing applications such as sight windows and quick-connects
Based on biocompatibility testing as defined by ISO 10993, Veradel® HC A-301 PESU demonstrates no evidence of cytotoxicity, sensitization, intracutaneous reactivity or acute systemic toxicity. The material is expected to pass USP Class VI testing that is currently underway. These well-documented compliance records along with FDA Master Access File (MAF) support can facilitate the design and regulatory application process for medical device OEMs, thereby accelerating time to market.
Veradel® HC A-301 PESU helps balance Solvay’s portfolio of transparent, sulfone-based healthcare polymers, which have a long history of proven performance in advanced healthcare applications. Radel® polyphenylsulfone (PPSU) is a super-tough, transparent polymer that can withstand more than 1,000 cycles of steam sterilization without significant loss of properties.
Veradel® HC A-301 PESU offers heat resistance that is on par with Radel® PPSU. The material’s high flow rate makes it particularly suited for injection molding thin-walled parts and components with complex geometries. Its stiffness is the highest of all medical-grade sulfone polymers.
Udel® polysulfone (PSU) is a tough, high-strength transparent polymer that offers higher heat resistance and better hydrolytic stability than polycarbonate.
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.
