Product Description

Quick Overview

LCP fiber, also known as Liquid Crystal Polymer Fiber, supplied in selected D grades from 50D to 400D.
The product range provides different modulus levels for cable reinforcement, optical fiber cable reinforcement and braiding applications.
High modulus type: generally used for optical fiber cable reinforcement.
High strength type: suitable for ordinary wire reinforcement and braiding.
The supplied property sheets provide standard values and measured values for elongation, modulus and finishing oil.
The supplied data also include thermal, physical and high-frequency electrical properties.

Product Introduction

LCP Fiber is designed for engineered reinforcement applications that require low moisture absorption, thermal stability, dimensional stability and defined electrical performance. The available material grades in the supplied specification files are 50D, 130D, 200D, 300D and 400D.

For application selection, high modulus grades are generally considered for optical fiber cable reinforcement, while high strength grades are suitable for ordinary wire reinforcement and braiding. Final grade selection should be confirmed against the cable construction and processing requirements.

Application Guidance

High Modulus Type for Optical Fiber Cable

High modulus LCP fiber is generally used in optical fiber cable reinforcement where the design requires a higher modulus level.

High Strength Type for Wire Reinforcement and Braiding

High strength LCP fiber is suitable for ordinary wire reinforcement and braiding applications where the material needs to support the cable structure and braiding process.
