Material and Polymer Product Testing

We meet specific customer requirements with high quality, no constraints on quantity, competitive prices and fast dispatch.

Our highly skilled and knowledgeable staff are specialists in all elastomeric polymers, continually pushing the boundaries of modern materials and processes.

If you know what you want from a seal, an oxygen/supply hose, lightweight ducting, cable tie or toilet float, we will design a new product, enhance an existing one, or develop a new polymer hybrid or blend that will give you exactly what you need.

Give us the most open spec...
'I just need something that will do this and I need it in a week'; or tell us what material and shape and weight it absolutely has to be; or just say 'I need you to make this for no more than 6p per unit'.

Our expertise in the polymer material range, capability and attributes means we can develop new polymer blends and hybrids that will add to the lifetime of a product, and reduce the cost of replacement, the out-of-service time, labour costs associated with frequent replacement, and inventory costs, to name but just a few.

We process and manufacture all polymer materials, including:

  • fluorosilicone
  • silicone
  • polychloroprene
  • fluorocarbon
  • EPDM
  • polyurethane
  • natural rubber
  • hybrids and blends

The extreme environments within which aerospace polymer products such as rubber seals, fluorosilicone seals, fuel lines and nose cones operate mean failure is simply not an option. The materials and material compounds must be tested to the limits and beyond of the extremes they will encounter; the components themselves must also be tested to their own limits, which may be different.

We have fully-equipped testing facilities which enable us to perform a wide range of testing in-house and to provide qualification and test data to many different specifications.

Test equipment includes many advanced features to give enhanced accuracy, reliability and test conditions that are relevant to product service requirements.

Testing includes:

  • Tensile strength
  • Compression Set
  • Hardness
  • Tear Strength
  • Heat ageing
  • Fluid compatibility
  • Fire resistance
  • Pressure testing
  • Electrical resistance
  • Dynamic Testing

Specialised Polymer Engineering provides a wide range of material/compound and component testing. Our standard tests include;

Mechanical Testing
E.g. density, tensile strength, tensile impact

Thermal Analysis/Characterisation Testing
E.g. thermal expansion coefficient, melt flow index (MFI)

Optical Testing
E.g. opacity, colour

Fire Resistance Testing
E.g. spread of flame, limiting oxygen index

Durability Testing

  • E.g. oven ageing
  • thermally accelerated ageing
  • fatigue testing
  • tensile creep
  • compressive creep
  • torsional creep
  • hydrostatic creep

Chemical Testing

  • E.g. FT-IR (Infrared Analysis), which is the finite analysis using infrared.
  • DSC (Differential Scanning Calorimetry)
  • TGA (Thermo Gravimetric Analysis), which is used to analyse the ingredients of a product.

Individual Component Testing
Component testing can give quite different test results from material or compound testing, as the material is subjected to heat, torque, stretching etc. It is vital, therefore, that both take place to ensure 100% quality and accuracy to spec.

Component failure Testing

  • E.g. incorrect material selection
  • chemical & environmental interactions
  • response to long term loads
  • processing errors
  • inappropriate design

A client needed a seal to withstand a very broad range of temperatures but remain flexible; it also had to be very tough and longwearing, which silicone itself isn't.

So SPE created a SI/Polyurethane hybrid, which gave the resistivity to a wide temperature range, plus the toughness needed (and made it impermeable to H20 which polyurethane usually isn't).

So instead of the seal being replaced every 15 flights, it only needs to be replaced every 60 flights which means money was saved on lower replacements, less inventory, less downtime and it was visually more appealing than having seals coming apart.
