GFC PETSTRAND® Binder Yarn is used for binding of SZ-stranded optical fibers at high speed. They are available in Low Shrinkage (LS) and Ultra Low Shrinkage (ULS) versions.
With optical fiber cable designs becoming more and more compact, GFC supplies low shrinkage binder yarn as a standard. PETSTRAND® Binder Yarn can be supplied as dual-end versions. Two parallel yarns are pulled simultaneously resulting in increased process speeds up to 50%.
Standard Low Shrink
Shrinkage levels lower than 3% and Ultra levels as low as 0.50%.

Driven by innovation. Designed by experts. Proven through performance.
PETstrand® InstantDry Core™ is an advanced spun polyester water-blocking yarn engineered for fiber optic cable buffer tube and core applications. Designed for rapid moisture management and long-term reliability, it helps protect critical fiber components while supporting efficient cable manufacturing and consistent field performance.
PETstrand FR is a flame-retardant polyester binder yarn engineered for telecommunications cable applications requiring enhanced fire performance without sacrificing high tenacity, low shrinkage, or processing efficiencies
​
Built on the proven PETstrand platform, PETstrand FR is designed to support cable constructions that target improved flame behavior, structural integrity, and long-term durability across a range of indoor installation environments.​
​Designed for Modern Network Environments
From dense urban deployments to hyperscale data centers, PETstrand FR supports cable designs that prioritize safety, reliability, and long service life. As network infrastructure expands into more complex environments, reinforcement materials must contribute not only to strength — but to overall system resilience.
