Professional China Phosphated Steel Wire For Optical Cable Strengthening - Polybutylene Terephthalate (PBT) for Optical Fiber Cable – ONE WORLD Detail:

1. Product Introduction

PBT(Polybutylene terephthalate) is a milky white translucent to opaque, crystalline thermoplastic polyester. It is a thermoplastic polybutylene terephthalate formed by polycondensation of terephthalic acid and butylene glycol under high temperature and catalytic conditions. PBT has excellent mechanical properties, electrical insulation properties, oil resistance, chemical corrosion resistance, easy shaping and low moisture absorption. It is the most commonly used extruding material for outdoor optical cable loose tubes.
In the communication optical cable, the optical fiber itself is very fragile. Although the mechanical strength of the optical fiber has been improved after the primary coating, it is still not enough for the requirements of the cable, so the secondary coating is required which is the most important mechanical protecting method for optical fibers in the manufacturing process of optical cables, because coating not only provides further mechanical protection against compression and tension, but also creates excess length of optical fibers. Because of its good physical and chemical properties, PBT is usually used as the extrusion material for the secondary coating of optical fibers in outdoor optical cables.
We can provide OW04A, OW02 and other grades of PBT materials. Our PBT materials have the following characteristics:
1) With excellent mechanical strength, it can ensure that the produced loose tube has high strength without being crushed;
2) With excellent thermal stability, dimensional stability, chemical resistance and good compatibility with fiber paste and cable paste;
3) With good processing performance and stable molding performance, it is suitable for high speed extrusion. Among them, OW02 type PBT has better processing fluidity and is suitable for higher-speed extrusion production. Its excellent lateral pressure resistance is also suitable for the processing and production of micro-optical cables.

2. Application

It is suitable for the production of secondary coating loose tube for outdoor communication optical fiber cable.
