Testo del prodotto
Implantable grade polyether ether ketone resin for permanent implants

VESTAKEEP® i2 G is a natural colored, standard viscosity polyether ether ketone (PEEK) that is especially designed for long term implantable medical devices. This grade is often used for injection molding processing technologies due to its good flowability.

Proven Biocompatibility of VESTAKEEP® i-Grades
The extra high purity and extended quality measures make VESTAKEEP® i-Grade materials an excellent choice for permanent implants.

For VESTAKEEP® i2 G, biocompatibility has been tested following ISO 10993-1 recommendations for permanent tissue/bone contact and USP Class VI.

VESTAKEEP® i2 G complies ASTM F2026 “Standard Specification for Polyetheretherketone (PEEK) Polymers for Surgical Implant Applications”.

A summary of biocompatibility test results is available upon request.

Biocompatibility tests available for i2 G


Processing of VESTAKEEP® i-Grades
VESTAKEEP® i2 G can be processed by common melt processing techniques like injection molding and extrusion.

We recommend a melt temperature between 360°C and 380°C during the injection molding process. The mold temperature should be within a range of 160°C to 200°C, preferably 180°C.

Our technical experts would appreciate to give you support regarding the special requirements for the processing of VESTAKEEP® i2 G.

Delivery of VESTAKEEP® i-Grades
VESTAKEEP® i2 G is supplied as cylindrical pellets in 10 kg boxes with moisture-proof polyethylene liners.
