product description

Product Introduction

PBT is milky white or milky yellow translucent to opaque thermoplastic polyester particles. PBT has excellent mechanical properties, electrical insulation properties, oil resistance, chemical corrosion resistance, easy moulding and low moisture absorption, etc., and is the most commonly used material for optical fiber secondary coating.

In the optical fiber cable, the optical fiber is very fragile. Although the mechanical strength of the optical fiber is improved after the primary coating, the requirements for cabling are still not enough, so the secondary coating is required. The secondary coating is the most important mechanical protection method for the optical fiber in the optical fiber cable manufacturing process, because secondary coating not only provides further mechanical protection against compression and tension, but also creates excess length of optical fiber. Due to its good physical and chemical properties, PBT is usually used as an extrusion material for the secondary coating of optical fibers in outdoor optical fiber cable.

We can provide OW-6013,OW-6015 and other types of PBT material for secondary coating of optical fiber cable.
The PBT we provided has the following characteristics:
(1) Good stability. Small shrinkage scale, small volume changing in using, good stability in forming.
(2) High mechanical strength. Large modulus, good extension performance, high tensile strength. The anti-lateral pressure value of tube is higher than the standard.
(3) High distortion temperature. Excellent distortion performance under large load and small load conditions.
(4) Hydrolysis resistance. With excellent resistance to hydrolysis, making optical fiber cable more longer life than standard requirements.
(5) Chemical resistance. Excellent chemical resistance and good compatibility with fiber paste and cable paste, not easy to be corroded.

Application

Mainly used for the secondary coating production of the optical fiber of the outdoor loose-tube optical fiber cable.
