PEEK Features and Benefits

1、 Material Overview

PEEK and PI are high-performance materials synthesized by Wiggs in the UK and DuPont in the US, respectively, and hold invention patents. PEEK and PI have excellent comprehensive performance in high-performance polymers that cannot be compared to other general-purpose plastics, and have excellent performance suitable for various harsh environments. They have been successfully and widely used in various industries such as aerospace, automotive, electronic semiconductors, electromechanical, and other demanding occasions. It is the preferred material for users to develop new products, improve product service life and reliability.

2、 Features and advantages

◆ High temperature resistance
The long-term use temperature certified by UL in the United States is 260 ℃. Even when the temperature reaches 300 ℃, good mechanical properties can still be maintained

◆ Wear resistance
In many extremely harsh application environments such as high temperatures, high loads, and strong corrosion, PEEK polymers and their composite materials have good wear resistance.

◆ Self lubrication
It has a low coefficient of friction and can achieve oil-free lubrication, and can work in medium such as oil, water, steam, weak acid and alkali for a long time.

◆ Corrosion resistance
Insoluble in ordinary solvents, it has good corrosion resistance to various organic and Inorganic chemistry chemical reagents.

◆ High strength
It has good mechanical strength in plastics. It also has high rigidity and surface hardness.


Easy to process
Parts can be directly processed using injection molding technology. It can be used for turning, milling, drilling, tapping, bonding, Ultrasonic welding and other post-processing.

◆ Resistance to hydrolysis
PEEK products can still work continuously for thousands of hours without significant performance degradation when soaked in steam with a temperature exceeding 250 ℃ or in high-pressure water.

◆ Flame retardancy
Without the use of any additives, the flammability level of the 1.45mm thick PEEK sample is UL94 V-0.

◆ Low smoke and non-toxic
The amount of smoke and toxic gas during combustion is particularly low.

◆ Electrical performance
Stable and excellent electrical performance can still be maintained over a wide temperature and frequency range.

◆ Radiation resistance
Has extremely strong resistance to high doses γ The performance of radiation and mechanical properties can be fully preserved, and can be used as radiation resistant parts in nuclear equipment.

◆ Stable size
shortcoming
The injection process is demanding and the machining process requires high requirements.
