Introduction

PEEK Materials Properties Guide

VICTREX PEEK polymer provides exceptional performance over a wide range of temperatures and extreme conditions. It is a linear, aromatic, semi-crystalline polymer widely regarded as one of the highest performing thermoplastics in the world. It provides a unique combination and range of high performance properties.


VICTREX PEEK polymers have prompted advances across industries. They remain a source of active innovation. As a metal replacement solution, these high-performance polymers help meet key engineering requirements in critical components.

PEEK PROPERTIES

A multi-talent with proven performance

PEEK polymers are well suited for extreme and demanding environments, whether in the form of powder, pellets, or compounds or forms and parts. The light thermoplastic can support multiple requirements at the same time – to solve material limitations in applications, often replacing metals, and to meet cost-efficiency and sustainability needs.
