PEEK MATERIAL PROPERTIES

MATERIAL GRADE

ARKPEEK-1000: 100%PEEK 01

Produced from virgin polyetheretherketone resin and offers the highest toughness and impact resistance of all types.

ARKPEEK-CF30: 30% Carbon Fiber + 70% PEEK 02

Carbon fiber reinforcement lends the material a high level of rigidity and creep strength, high mechanical strength and heat conductivity values.

ARKPEEK-GF30: 30% Glass Fiber + 70% PEEK 03

Glass filled PEEK exhibits increased mechanical strength and high rigidity. improved creep strength and dimensional stability are achieved by this glass filled PEEK. These properties make this material suitable for use in parts which are exposed to high static loads over long periods in high temperature conditions.

ARKPEEK-MOD: 10% Carbon Fiber + 10% PTFE +10% Graphite 04

High performance engineering plastic with product characteristics including excellent sliding and abrasion & wear resistance, high mechanical strength and high dimensional stability. The long term service temperature range of PEEK Rod is from -30°C to 250°C and has a short term maximum service temperature of 310°C.
