DOW WIRE & CABLE COMPOUNDS DEVELOPS HIGH-PERFORMANCE
SOLUTIONS FOR FIBER OPTIC CABLE APPLICATIONS
|
HOUSTON, Texas - Dow Wire & Cable Compounds,
a business group of The Dow Chemical Company and its subsidiaries,
now offers new materials for fiber optic telecommunications cables
that provide improved performance, cost efficiencies and manufacturing
cost savings. Novel products based on developmental INSPIRE* performance
polymers feature high melt strength and a balance of high stiffness
and toughness. They also offer good potential to advance overall
cost and performance improvements in key optic cable applications.
For buffer tube use, these high stiffness/high toughness materials
contribute substantially improved crush resistance and cable grease
compatibility versus conventional IMPP (impact modified polypropylenes)
currently in use, as well as physical properties approaching or
superior to those of polybutylene terephthalate. Enhanced compatibility
with the less expensive buffer tube filling gels offers system cost
advantages in addition to clearly superior physical properties,
compared to conventional IMPP, which requires higher-viscosity and
higher-priced gels.
For fiber optic core tube (center tube) and slotted core applications,
Dow's high melt strength polymers offer good extrusion characteristics
with minimal sag, while providing the desirable high modulus and
corresponding crush resistance of conventional polypropylene materials.
These materials have also demonstrated the necessary balance of
other performance characteristics such as good surface smoothness,
low post-extrusion shrinkage contributing to excess fiber length
and signal attenuation, and sufficient cold-impact performance for
outdoor installation and use in cold climates.
As the world's leading global producer of polyolefin-based wire
and cable materials, Dow Wire & Cable Compounds, a business group
of The Dow Chemical Company, brings more than 50 years' experience
to the power, telecommunications, flame retardant and end-user markets.
Our polyethylene compounds are used as insulation and jacketing
materials, providing a unique combination of mechanical strength,
flexibility, electrical properties, aging stability and processability.
Dow Wire & Cable Compounds, www.dowwireandcable.com, creates value
for global customers by supplying material and compounding solutions
that are backed by solid research and development, product development,
engineering and market validation expertise.
