产品描述
Implantable grade polyether ether ketone resin for permanent implants
VESTAKEEP® i4 G is a natural colored, high viscosity polyether ether ketone (PEEK) that is especially designed for long term implantable medical devices. This grade is often used for extrusion processing technologies.
Proven Biocompatibility
The extra high purity and extended quality measures make VESTAKEEP® i-Grade materials an excellent choice for permanent implants.
For VESTAKEEP® i4 G, biocompatibility has been tested following ISO 10993-1 recommendations for permanent tissue/bone contact and USP Class VI.
VESTAKEEP® i4 G complies ASTM F2026 "Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implant Applications".
