Characteristics of polyether ether ketone

2019-09-07

High temperature resistance -- PEEK has a high glass transition temperature (Tg=143 ° c) and melting point (Tm=334 ° c), and its thermal deformation temperature under load is up to 316 ° c, long-term service temperature is 260 ° c, and instantaneous service temperature is up to 300 ° c. Polyether ether ketone

Mechanical properties of PEEK are rigid and flexible, especially for the alternating stress of fatigue resistance is very prominent, can be comparable to alloy materials.

Self-lubricity -- PEEK has excellent sliding characteristics, suitable for occasions with strict requirements for low friction coefficient and abrasion resistance, especially with carbon fiber, graphite, PTFE modified sliding brand PEEK abrasion resistance is very superior.

Corrosion resistance -- apart from concentrated sulfuric acid, PEEK is insoluble in any solvent and strong acid and alkali, and is hydrolytic resistant, with high chemical stability.

Flame retardant - polyether ketone PEEK self-extinguishing, even without any flame retardant, can reach UL standard 94v-0.

Workability -- due to the characteristics of high temperature and good fluidity, and high thermal decomposition temperature, PEEK can be processed in a variety of ways: injection molding, extrusion molding, molding and melt spinning.

The processing method of polyether ether ketone (PEEK) : processing with hard alloy knife and adding cooling fluid to prevent the material from producing stress.
