Peek Plastic Material Features

PEEK Introduction

PEEK(Polyetheretherketone) is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy cnc machining and high mechanical strength. It can be manufactured and machined into various mechanical parts, such as automotive gears, oil screens, shifting start disks. ;

PEEK Material Features

High temperature resistance

PEEK has a high glass transition temperature (Tg = 143 ℃) and melting point (Tm = 334 ℃). Its thermal deformation temperature under load is up to 316 ℃, and its long-term use temperature is 260 ℃. Instantaneous The use temperature can reach 300 ℃. Polyetheretherketone

PEEK Machining Properties

PEEK machining properties has rigidity and flexibility, especially the fatigue resistance under alternating stress is very outstanding, and can be comparable to alloy materials.

Self-lubricating property

PEEK has excellent sliding characteristics, which is suitable for the occasions with strict requirements for low friction coefficient and wear resistance, especially the sliding grade PEEK modified with carbon fiber, graphite, and PTFE. superior.

Corrosion resistance

In addition to concentrated sulfuric acid, PEEK is insoluble in any solvents and strong acids and alkalis, and is resistant to hydrolysis and has high chemical stability.

Flame retardancy

PEEK has self-extinguishing property, even without any flame retardant, it can reach UL standard 94V-0.

Ease of machining

Because PEEK has the characteristics of good high-temperature fluidity and high thermal decomposition temperature, a variety of machining methods can be used: injection molding, extrusion molding, compression molding, and melt spinning. ( Polyetheretherketone ) PEEK Machining method of polyetheretherketone: Use a hard alloy knife to process and add a cooling liquid to prevent material stress.
