PEEK Advantages

1. What is PEEK ?

Poly (ether ether ketone)(PEEK) is a linear polymer whose main chain is composed of Aryl, ketone and ether bonds. PEEK has a large number of benzene rings in its molecular chain, so its heat resistance can match that of polyimide, while two ether chains and a renegade group provide the material with flexibility and excellent workmanship.

2. PEEK unfilled, a popular choice, why?
UNFILLED PEEK has excellent physical and chemical properties in its own right. Its characteristics of high strength, high toughness, corrosion resistance, high temperature resistance, good insulation, high purity basically meet most of the industrial environment.

3. PEEK and types of its modification
In addition to the unfilled PEEK, we will modify it as needed. In order to satisfy the different use case, we carry on the PEEK according to the filler and the modified characteristic.


1、Is JUNHUA PEEK different from other commercial PEEK?
Not all PEEK materials are the same, different manufacturers of PEEK will be different. But for PEEK material of the basic mechanics, thermodynamics and electricity, with the continuous improvement of Peek polymerization process, in fact, have not much difference. For example, the performance of Junhua Peek is similar to that of VICTREX PEEK450G, Keaspire PEEK and VESTAKEEP 5000G, with 95 per cent of the product applications being essentially the same. It’s more about the fluidity of the material.

2、What is the natural color of JUNHUA PEEK material?
PEEK natural color close to Khaki or Brown, Khaki, etc. . We often use two kinds of natural color and black, according to different needs, we can also produce different color particles.

3、What is the chemical solvent resistance of JUNHUA PEEK?
JUNHUA PEEK chemical resistance is very good, we often say that chemical resistance is also known as corrosion resistance. Peek contains a large number of benzene ring structure, so that it can withstand most of the chemical drugs, such as gasoline, kerosene, lubricants, formic acid, acetic acid, hydrochloric acid, caustic soda, hydrogen peroxide and so on. Only strong oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, aqua regia, chlorine, etc. are not tolerated.
More information request, please send us inquiry for JUNHUA PEEK chemical resistance DATA SHEET

4、Does JUNHUA have certification for the PEEK grades?
YES, we have full certification, please send us inquiry for request.

5、What do you need to pay attention to when you keep PEEK?
As with most commercial PEEK, the ability to withstand UV light is skewed, so care should be taken to avoid light and ambient temperature during storage.

6、What should be paid attention to during injection molding of PEEK?
The first step is to check whether the temperature of the injection machine can reach 400 °C and that of the mould can reach 230°C. Secondly, we need to choose suitable flowing PEEK raw materials according to the structure of the products. The PEEK3600G with high fluidity is suitable for making thin-walled products, and the PEEK5600G with medium fluidity is suitable for making normal products, the PEEK7600G with low fluidity is suitable for making products that require high toughness, such as screws.
