Optical Cable FRP Strength Member Resin
LC-5940

Precision-engineered pultrusion resin for manufacturing high-strength, non-conductive FRP rods used as central strength members in fiber optic cables. Delivers exceptional dimensional stability and dielectric performance for global telecommunications networks.

The Backbone of Global Communications

LC-5940 is a specialized unsaturated polyester resin formulated specifically for the high-speed pultrusion of FRP strength members in fiber optic cables. These non-metallic rods provide the tensile strength needed to support delicate optical fibers during installation and service, while their inherent electrical insulation protects against lightning strikes and electromagnetic interference. The resin's optimized reactivity enables pultrusion speeds up to 80 meters per minute, while maintaining tight diameter tolerances (±0.01mm) critical for cable assembly automation. With superior glass fiber wetting and low water absorption, LC-5940 ensures long-term mechanical stability in aerial, duct, and submarine cable installations.

High-speed pultrusion capability (60-80 m/min)
Excellent dielectric properties for lightning protection
