Polymers development yields
high tenacity multifilament yarn
Diolen, a JV of Ticona Engineering Polymers and Kureha Corporation, offers
first high tenacity multifilament yarn using Fortron PPS.
High-performance fiber application for Fortron polyphenylene sulfide
- Diolen Industrial Fibers is offering the first high-tenacity multifilament
made with Fortron* polyphenylene sulfide (PPS), which is produced by Fortron
Industries LLC, a joint venture of Ticona Engineering Polymers and Kureha
Corporation. This high-performance yarn, called Diofort**, is inherently
flame-retardant, has high durability, toughness and chemical resistance,
and withstands extremely hot environments that can stress conventional
multifilaments to their performance limits.
Diofort multifilament is used to reinforce hydraulic oil hoses in power
steering systems where it helps to reduce vibration and noise. It also
can be applied in other vehicle systems, such as fuel lines and charge-air
coolers, to provide resistance to high pressure and temperature while
allowing for hose flexibility. Other possible applications range from
industrial filter systems for flue gases and aggressive liquids to composites
for aerospace systems.
Diolen makes Diofort yarn in a multi-stage process. After plasticizing
and extruding Fortron PPS in a multifilament extruder at the desired diameter,
individual filaments undergo controlled stretching in a well-defined temperature
range. This yields a high-tenacity multifilament yarn having excellent
mechanical properties for use as reinforcement or in fabrics, nonwovens
or other textiles. The yarns can be combined with glass, carbon and other
fiber polymers to yield blended fabrics.
Fortron PPS gives the Diofort yarns and their fabrics excellent chemical
resistance to withstand aggressive media, low water absorption, high strength
to 190°C (about 375°F) and flame retardancy.
Diolen Industrial Fibers is a leading European polyester company with
an international reputation for developing and manufacturing Diolen**
PET yarns and Diofort PPS yarns, both of high-tenacity, and high-quality
chips of various polymers. Diolen yarns are used to build and strengthen
a wide variety of industrial applications where safety and reliability
are key factors, including tires, seat belts, tarpaulins, billboards,
roofing constructions, hoses and mooring ropes.
Diolen customers worldwide are served from two production plants, in Germany
(Obernburg) and the Netherlands (Emmen). In addition to these plants,
Diolen has its own research institute in Emmen and sales offices in Arnhem,
the Netherlands and Scottsboro, AL, USA. The company’s headquarters
is located in Arnhem. Diolen Industrial Fibers employs some 1.000 specialists
worldwide.
Announced last year at this time, The Fortron Industries LLC PPS resin
manufacturing & compound sales plant located in Wilmington, North
Carolina USA, is on schedule and is to be completed in the third quarter
of 2007. The $65 million expansion of the resin manufacturing plant will
double the plant's Fortron* PPS (polyphenylene sulfide) capacity to 15,000
metric tons per year.
Ticona, the engineering polymers business of Celanese Corporation, produces
and markets a broad range of high performance products.
