High-Performance TPU-Vinyl Alloys for Medical and Specialty Applications

VYTHENE® by Alphagary is a specialized line of thermoplastic polyurethane (TPU) compounds alloyed with vinyl, designed to meet the rigorous demands of medical and specialty applications. These materials are engineered to be tough and kink resistant, designed for applications that require the components to bend, flex, and recover repeatedly.  

Why VYTHENE®

Why VYTHENE®

The unique TPU-vinyl alloy composition of VYTHENE compounds provides a balance of toughness and processability. Additionally, these transparent compounds are formulated to withstand various sterilization methods, including ethylene oxide (EtO), autoclave, and radiation, making them an ideal candidate for a variety of healthcare applications. 

 

Characteristics and Properties

VYTHENE® compounds are ideal for environments involving repeated mechanical stress including flexing, compression, and movement. Key characteristics and properties include:​

  • Built for repeated flexibility and recovery: maintains mechanical integrity under continuous use and cyclic deformation.
  • Tough and kink-resistant: supports reliable performance and helps maintain flow paths in tight/dynamic configurations.
  • Transparent: enables visual inspection and fluid visibility; supports clean aesthetics in healthcare devices.
  • Resilient under repeated mechanical stress: performs well in environments involving flexing, compression, and movement over service life.
  • Vinyl + Polyurethane alloy platform with strong processing advantages: bridges flexibility and toughness, good flow properties and no-pre-drying required.
