Send a drawing or a sample and we will match to a suitable grade, or work to the specification your customer requires (BS 7531, DIN 3754, ASTM F104 and similar).
Specialist Grades
Aerospace, defence and space grade materials
Many of our customers operate in regulated sectors where material certification and full traceability are mandatory. We mould to customer-supplied specifications and can source compounds qualified to the standards your industry demands.
Aerospace & Defence Specifications
We supply materials qualified to DTD, AMS-R-25988, MIL-DTL-25988 and wider AMS standards. Certificates of conformance, batch traceability and test reports are available on request. If your drawing calls for a specific spec, we will source and mould to that exact grade.
Coatings, Primers & Adhesives
Bonded inserts, coated seals and primed surfaces are routine for us. We work with a range of surface treatments and adhesive systems to meet adhesion, corrosion resistance and environmental sealing requirements.
Space Grade Materials
Low outgassing, radiation-resistant and ultra-high vacuum compatible elastomers for satellite, launcher and deep-space applications. Material data packs including outgassing test results can be provided where required.
