Application Note

Amorphicity and Crystallization of PEEK

Introduction

PEEK (polyetheretherketone) is a common polymeric material used for a variety of applications. Normally it is supplied as an amorphous material. Normally it is supplied as an amorphous material. This material, when examined in a PerkinElmer® DMA 8000, shows classic relaxation behavior with a sharp and defined glass transition. The material also displays a recrystallization after passing through the Tg. This application note demonstrates the ability of DMA 8000 to investigate both relaxation events and recrystallization in a polymeric sample.
