What Is PEEK Plastic ?

PEEK Plastic (Polyether Ether Ketone ) is a high polymer composed of repeating units containing one ketone bond and two ether bonds in the main chain structure, and is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a type of semi-crystalline polymer material and can be used as high temperature resistant structural materials and electrical insulation materials.

Why Use PEEK Plastic?

PEEK Plastic is an aromatic crystalline thermoplastic polymer material with a melting point of 334°C. It has high mechanical strength, high temperature resistance, impact resistance, flame retardancy, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance and good electrical properties.

Advantages of PEEK plastic

The Benefits

It has a high glass transition temperature (Tg=143°C) and melting point (Tm=343°C), its load heat distortion temperature is as high as 316°C, and its instantaneous use temperature can reach 300°C.

Rigid and flexible, especially the fatigue resistance under alternating stress is very outstanding, comparable to alloy materials.

It has excellent sliding properties and is suitable for occasions that strictly require low friction coefficient and wear resistance, especially PEEK, which is modified by mixing carbon fiber and graphite in a certain proportion, has better self-lubricating performance.

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

It is self-extinguishing, even without adding any flame retardant, it can reach the 94V-0 level of UL standard.

It has the characteristics of good high-temperature fluidity and high thermal decomposition temperature, and can be processed in a variety of ways: injection molding, extrusion molding, compression molding, and melt spinning.

The stripping resistance is very good, so it can be made into thinly coated wires or magnet wires, and can be used under harsh conditions.

It has the best fatigue resistance among all resins.

The ability to withstand high radiation is very strong, surpassing the polystyrene with the best radiation resistance among general-purpose resins. It can be made into a high-performance product that can still maintain good insulation ability when the gamma irradiation dose reaches 1100 Mrad.

PEEK and its composite materials are not chemically affected by water and high-pressure water vapor, and products made of this material can still maintain excellent characteristics in continuous use in high-temperature and high-pressure water.

PEEK has the lowest smoke among plastics.

 It has good electrical insulation properties and maintains to a high temperature range. Its dielectric loss is also very small at high frequencies.

It has excellent dimensional stability characteristics, which is very important for some applications. Changes in environmental conditions such as temperature and humidity have little effect on the size of PEEK parts, which can meet the requirements for use under relatively high dimensional accuracy requirements.
