Plastic solutions that meet the high demands of the aerospace industry

At Ensinger we have many years of experience combining technical and commercial understanding, to meet the high demands on materials and solutions for the aerospace industry. Technical and high performance aerospace plastics contribute to making applications more efficient and competitive in many areas of industry.

The characteristics of Ensinger's high-performance and engineering plastic materials meet the technical requirements for many of the systems and subsystems used in today’s ultra-modern advanced composite aircraft. The advantages of using lower weight materials for producing fuel efficient and low emission aircraft are clear, but there may also be benefits gained from the longer service life of components. Additionally, our aerospace materials are not affected by corrosion in the aviation operating environment.

The impressive properties of high performance plastics include their low weight and high strength. Significant weight savings can be achieved by switching from aluminum/steel, as many of our high performance polymers have a density of around 1.3 g/cm3 – in comparison, aluminium which has a density of 2.7 g/cm3.

Aircraft material solutions

Working in close cooperation with many of the leading aerospace companies and system manufacturers, Ensinger's team has established an impressive track record over many years as an aerospace supplier, developing optimum high performance plastic solutions, approved for use in the aviation industry. Ensinger's experience in the industry includes working with the industry's preferred Tier 1 suppliers.

Ensinger supplies a vast range of airplane components that are used in aircraft landing gear systems.

Solutions for Aerospace

Plastics for aircraft interior applications

Our portfolio of aerospace plastics contains materials that meet fire behaviour standards in accordance with FAR 25.853. Our plastics are constantly tested for flammability, smoke and toxicity. Many materials are suitable for cabin interior applications.

Strong materials

When selecting aerospace plastics, specific strength is a key indicator for high mechanical performance materials. This determines the tensile strength of a material relative to its density and indicates the strength-to-weight ratio.

Radiation resistant plastics

Depending on their field of application, plastics may come into contact with different types of radiation. Applications such as outer plane covers or satellite parts are examples of applications where radiation resistance is important. 

Electrically insulating materials

For aerospace plastics used in propulsion elements, control units or landing gears, good electrically insulating properties are essential.

Conductive plastics

Dissipation of electrostatic charge is essential for aerospace applications where highly sensitive electronic components are present.

Heat resistant plastics

Many aerospace plastic applications require thermally resistant materials, which at the same time have a good resistance to ageing.

Low outgassing plastics

Outgassing characteristics are very important when choosing materials in space applications where they will be subjected to a vacuum.

Finished and semi-finished parts FOR Aerospace

The complex machined parts for aerospace are produced in four Ensinger branches. They comply with precise standards concerning tolerances and surface finish. The companies in France, Great Britain, China and USA are certified according to AS/EN 9100.

For the aerospace industry the Ensinger injection moulding branches produce demanding precision parts and complete assemblies. In addition to insert and overmoulding, multi-component injection moulding is becoming increasingly important.
Thermoplastic profiles and tubes are produced in our headquarter in Germany. They are applied in many different places from cabin interiors to solutions for structural components.

For structural and semi-structural aerospace parts matrix materials such as PEEK, PEI and PPS are used for composites. Based on this the production of geometric complex parts is possible. The know-how of Ensinger opens up new opportunities in parts' design e.g. for clamps, cleats, leading edges and interior parts.

In the filaments you find the whole Ensinger expertise: from the compounds, which can be adjusted to customer requirements to the production of the filaments.

Strength, dimensional stability and creep resistance of parts made from TECASINT remain stable under extended mechanical strain and long service. High purity and low outgassing are more advantages of the non-meltable polyimides.

Stock shapes for Aerospace

Machinable plastics which are being used in aircrafts and aerospace must satisfy the detailed requirements of end customers and system suppliers in order to minimise the risks.
