PEEK semi-finished products
PEEK semi-finished products explained: sheets, rods, films and tubes – properties and applications. For design, development and production.
PEEK is one of the most high-performance engineering plastics. Several semi-finished product forms are available for design, manufacturing and demanding applications, differing in structure, tolerances and fields of application.
Each form has its own advantages – and significantly influences subsequent machining. This article provides an in-depth overview and also refers to relevant product pages so that you can find the right version directly.
PEEK sheets
PEEK sheets are the basis for highly precise milled parts. They offer excellent dimensional stability and are ideal for components that are permanently exposed to high temperatures or media. Typical applications are carrier plates, covers, coupling segments or components with tight tolerances.
In our range you will find, among other things, PEEK sheets natural: PEEK sheets natural (Shop) These sheets are characterised by high purity and a consistent material structure. They are preferably used in mechanical engineering, in medical technology and in high-temperature environments.

PEEK rods
PEEK rods are mainly used for components produced by turning. They are suitable for bushes, sliding guides, bearings, insulating sleeves or components that are exposed to high tribological loads.
In the shop you will find, among other things:
Both variants have excellent strength and friction values and are optimised for precise turned parts.
Technical basics: Material PEEK
PEEK films
Films made of PEEK are thin, flexible and yet extremely resilient. They are used in electronic assemblies, insulation, sensor applications and sealing elements. Their temperature and media resistance significantly exceeds that of most engineering films.
Typical application advantages:
- extremely low tolerances
- high purity
- resistant to oils, chemicals and heat
Background on development is provided by the PEEK history.
PEEK tubes
Tubes made of PEEK combine high rigidity with low weight and are ideal for media lines, spacers, insulating sleeves or components in the fluid and high-temperature sector. The extruded structure ensures precise inner and outer diameters.
Technical basis of production: Extrusion technologies
Selecting the right semi-finished product
The right choice depends on:
- required mechanics (turning, milling, cutting)
- tolerances and component geometry
- chemical and thermal load
- economic factors (offcuts, material utilisation)
For a complete material classification, the PEEK material science is recommended, which explains the structure, properties and limits of the material.
FAQ
Which PEEK semi-finished products are there? Sheets, rods, films and tubes in different tolerances and formats.
When do I use which semi-finished product form? Sheets for milled parts, rods for turned parts, films for insulation, tubes for media and structural components.
Are there PEEK semi-finished products in natural and black? Yes, in particular rods and sheets are available in both variants.
Why is PEEK so much in demand as a semi-finished product? Because it meets high temperature, media and wear requirements and can be machined with excellent precision.
