SYNX is ARMBURY's anti-slippage technology. A controlled inter-layer friction treatment is applied to the sheath–core interface during the braiding process, dramatically increasing the grip between the two layers. The result is minimal sheath slippage under load, more consistent handling, and a noticeably prolonged rope service life. SYNX is distinct from INTERCORE: INTERCORE is a true sheath-core bonding technology, while SYNX relies on physical inter-layer friction.
