What is PEEK Plastic?

PEEK (polyetheretherketone) is a highperformance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. It offers hydrolysis resistance to steam, water, and sea water. PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338oF (170oC). This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, and semiconductor.

Some of Peek’s material properties:

=> Chemical resistance: PEEK displays high resistance amidst a wide range of chemical environments, even including high temperatures. It can only be dissolved in concentrated nitric acid or sulphuric acid.

=>Long life: It is a hard, stiff and strong polymer. It displays good friction as well as wear properties.

=>Hydrolysis resistance: PEEK material can be exposed for a long period of time to high pressure water and steam without exhibiting any serious degradation.

=>High temperature resistance: When the process temperatures go beyond the limit of what conventional plastic materials can withstand, it is advisable to go for PEEK.

The common PEEK material options:

1) Virgin PEEK (unfilled)– is naturally abrasion resistant.
2) Glass-Filled PEEK offers enhanced mechanical and thermal properties over those of basic PEEK, plus excellent resistance in harsh chemical environments and is electrically insulative.
3) Bearing Grade PEEK– has enhanced bearing and wear properties. TECAPEEK PVX is an ultra high performance bearing material with wear enhancing additives.
4) FDA Compliant PEEK– grades available that meet FDA requirements.

Application of the PEEK products:

PEEK is widely used for:

1) Aerospace:

PEEK is ideal for exterior aerospace conditions where the material comes into contact with atmospheric particles and low temperatures. The material is also favored because it is light weight, chemically inert, and relatively inexpensive.

2) Filter Manufacturing:

Biodiesel fuel filters: Biodiesel has been recognized worldwide as an alternative channel of energy because of its immense benefits. However, biodiesel degraded the standard filters as these were prepared from PA. PEEK is not effected by biodiesel and hence provides good sustainability for a long time.

Membrane spacer-battery: This is a mixed material which is used to separate different layers in a battery. PEEK, with a thickness of 50 microns, is thinner than the conventionally used polypropylene at 195 microns. Again, due to good resistance to acid and chemicals along with controlled porosity, PEEK is considered a high quality material to produce modern products.

Vacuum belt filters: Vacuum belt filtration is a process where chemicals are de-watered and dried. The drying process is accomplished by running the chemicals through a filter on a belt. Different kinds of chemical manufacturers like to use PEEK to make the filter itself more than polyester, which is less durable.

3) Healthcare:

Implant Material: PEEK is quite flexible, durable and strong in nature. It does not harm body or skin so it is very useful to repair soft tissues and grafts.

Dialysis pump filter: In dialysis, malfunction of the pumping mechanism causes severe problems and hence a good pump is required which is not effected by heat or cold. For this reason, PEEK, which has a high temperature resistance and low moisture absorption, is an apt choice.

4) Food and Beverage:

Food drying: Processes requiring dehydration for the production of powders, pastes and granules demand temperatures as high as 150°C. Currently PET fabrics are used but when temperatures as high as 190°C are required along with the same characteristics and shrinkage level as PET, Polyetheretherketone is a very good option.

Feed drying: At the end of production, some animal foods are dried on a belt which reaches a temperature of 150°C. PEEK is the material often used in this application because of its high temperature resistance.

5) Chemical and Pharmaceutical:

Pharmaceutical products including centrifuges and disc filters: Medical equipment is cleaned at temperatures reaching up to cleaned 150°C. Many plastic materials such as PA, PET, E-CTFE, PVDF can’t sustain such a high temperature. PEEK is extremely suitable for this kind of filter as it stays the same even at high temperatures and provides good flexibility. Moreover, it is less susceptible to contamination and is also available at an affordable price.
