INTERCORE

What It Is

INTERCORE is a manufacturing process that bonds the sheath and core of a kernmantle rope into a single, integrated structure using a proprietary thermoplastic-based bonding system. Applied during construction, INTERCORE prevents the sheath from migrating independently of the core — a phenomenon known as sheath slippage that reduces rope lifespan and safety. The result is a rope that retains its handling characteristics and structural integrity over a long service life, achieving 0% sheath slippage in pull-through testing.

Why It Matters

Sheath slippage causes bunching that creates uneven diameter and feeds poorly through devices

Slipped sheaths expose core fibers to abrasion, UV, and contamination — accelerating degradation

Better force distribution between sheath and core means the entire rope cross-section shares the load

Extends service life significantly in high-friction applications like rope access and tree care

How It Works

The rope passes through a sizing die where it is uniformly compressed inward, and a proprietary thermoplastic-based bonding agent is integrated at the sheath–core interface during manufacturing. The gaps between the core and the sheath are compacted and chemically bonded, leaving no room for relative movement. The resulting bond increases internal cohesion and prevents core–sheath slippage during use — without reducing rope flexibility.
