OEM / ODM

Customized to your cable design

Standard products cover the majority of cable and reinforcement designs. Where a construction requires a non-standard specification, we manufacture to your requirement under OEM or ODM terms.

  • Custom linear density (denier / dtex) and filament count
  • Assembled, twisted and plied constructions to specified twist level (TPM)
  • Specified tenacity, modulus and elongation windows
  • Custom bobbin, carton and pallet configurations, including private-label packaging
  • Agreed specification, CoA format and release criteria per order

Applications

Where our aramid yarn is used

Fiber optic cableCentral and peripheral strength members, stranded or served reinforcement layers in indoor, outdoor and all-dielectric cable constructions.
Tire & rubber reinforcementTire cord, sidewall and cap-ply reinforcement, hoses, belts and rubber goods — a lightweight skeleton replacing steel wire.
Conveyor belts & hosesLong-distance, high-load conveying with over 50% skeleton weight reduction versus steel cord, around 30% energy savings and up to 2× service life.
Friction materialsAsbestos-free brake pads and clutch facings with stable high-temperature friction performance and wear resistance.
EV battery protectionImpact-resistant para-aramid fabrics as the protective skeleton of battery enclosures — thermal-runaway and crash safety, extending to eVTOL.
Protection & infrastructureBallistic vests and helmets, structural strengthening of bridges and columns, deep-sea mooring ropes and industrial textiles.
