Zylon® / PBO

Back to top

Zylon® Polybenzyloate (PBO) is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet spinning process.

Zylon / PBO was first developed in the 1980’s and studies suggest the mechanical strength to be more than two times stronger than any other commercialized synthetic fiber. It is also the first organic fiber whose cross-sectional strength outperforms both steel and carbon fiber. Its high creep resistance and tensile strength potentially makes Zylon / PBO as one of the strongest synthetic fibers in the overall fibers market.

The strength of ZYLON® / PBO decreases in the condition of high temperature and high humidity. To maintain its mechanical properties, the fiber should be stored free from exposure to light, high temperature and humidity.

The manufacturing costs involved with the production of Zylon / PBO are also very high, therefore PBO fibers are used mainly in demanding applications such as strength members in defense-application products.

Features / Benefits

  • Excellent strength & modulus properties
  • Good flame resistance
  • Excellent thermal stability
  • Excellent resistance to creep
  • Good chemical resistance

Disadvantages

  • Very poor UV resistance
  • Poor compressive strength
  • Strength loss in exposure to strong acids

Applications

  • Strength member
  • Defense and military applications

Toro 12×12

Back to top

Toro™ 12×12 is a 12-strand braided rope in which each of the 12 strands is, in turn, a 12-strand rope, or braided primary strand. Toro is manufactured from high tenacity High Modulus Polyethylene (HMPE).

This patented construction addresses the most critical properties of the fibers to provide a very high strength translation efficiency for larger ropes. This design allows for long lay lengths, making rope that is more flexible for bending applications, easy to inspect, and can be quickly spliced using standard 12 strand splicing techniques. Toro 12×12 is supplied with our standard polyurethane finish, although other coatings can be applied to suit specific applications.
