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. All of the aircraft manufacturers have chosen to benefit from the use of polymers where alloys were previously used, to a significant extent. We have a wide range of materials that are tested and approved in accordance with aerospace customer’s specifications. Furthermore, Ensinger's materials can be tested, certified and approved to meet your specific, exacting requirements – from raw material inspection through to final inspection of the machined or semi finished aerospace components.

Solutions for the space industry

As a supplier to the space industry, Ensinger plastics are specified for many applications. In satellites, parts are used for applications such as solar array deployment systems, cable insulating blocks and platform systems.

Ensinger materials undergo the specific testing required by the end user to meet their arduous requirements for aerospace supply. Typical requirements met by Ensinger materials supplied to the space industry are high strength under severe vibration, low/ultra-low outgassing in vacuum, and resistance to high radiation levels. Ensinger has experience working with companies such as Airbus Defense and Space as well as with several space institutes/universities.


Benefits FOR Aerospace

AS/EN 9100 expertise at your disposal

Ensinger operates four machining plants that are certified according to AS/EN 9100: in France, Great Britain, China and USA. These have approvals for various machining processes from leading companies in the aerospace industry.

In addition, common materials such as PEEK, PA, POM, PEI, are specified by well-known OEM and Tier-1 suppliers.

Plug and play

Our global team of highly skilled staff will make sure that your components, however complex, arrive with you fit for purpose.

When the going gets tough

Outdoor applications are exposed to strong weather influences. With a weatherproof and UV resistant plastic material, which can withstand the negative impact of ultra-violet rays, the lifetime of the application is prolonged.

Optimised operating economy

Finished parts do not need additional protective treatment – correctly selected materials are resistant to all of the main greases and fuels used and are not prone to corrosion in the operating environment.

On time in full

Cost-effective in production, because your parts can be manufactured from readily available stock, which are produced commercially in high volumes, with short lead times. 

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 also keep high under high 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. Different requirements for the materials, like thermal and mechanical properites, density or flammability, apply to different areas of applications. Material specifications are thus developed individually.

Many of our materials are validated by leading aircraft manufacturers:

Aerospace CASE STUDIES

Thermal spacer

made of TECASINT

With Bepi Colombo to Mercury

Ensingers TECASINT material is part of Europe's first mission to Mercury with BepiColombo. The spacecraft for the mission are dependent on the function of the thermal control system (TCS), which keeps all the spacecraft's component systems within an acceptable temperature range during every phase of the mission. One part of the TCS is a thermal spacer, which functions as a barrier to high temperatures and radiation. This thermal spacer is a ring shaped plate made of TECASINT.
 

Heat sink

Cost-efficient greasing of your landing gear

Aircraft landing gear supports the entire weight of an aircraft during landing and ground operations. All of the articulating struts and rods in the landing gear require lubrication to ensure safe operation.
