Toho Tenax (東邦テナックス, Tōhō Tenakkusu) is an international company that supplies customers throughout the world with carbon fiber under the trade name Tenax.
Toho Tenax has been a member of the Teijin Group since 2000.
Since May 2018, Toho Tenax was integrated to its subsidiary Teijin, and all of the group's subsidiaries were renamed after Teijin.
Toho Tenax has production units in Japan, the US and in Germany. The main products are carbon fiber, oxidized poly-acrylic-nitrile (PAN) fiber and advanced composite material.
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components.
Carbon fibers or carbon fibres are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, motorsports, and other competition sports. However, they are relatively expensive compared to similar fibers, such as glass fiber, basalt fibers, or plastic fibers.
Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, as an asbestos substitute, and in various lightweight consumer items ranging from phone cases to tennis rackets.
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
Twaron is a para-aramid. It is a heat-resistant and strong synthetic fibre developed in the early 1970s by the Dutch company Akzo Nobel's division Enka BV, later Akzo Industrial Fibers. The research name of the para-aramid fibre was originally Fiber X, but it was soon called Arenka. Although the Dutch para-aramid fiber was developed only a little later than DuPont's Kevlar, the introduction of Twaron as a commercial product came much later than Kevlar due to financial problems at the AKZO company in the 1970s.
Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack. PPS is used in filter fabric for coal boilers, papermaking felts, electrical insulation, film capacitors, specialty membranes, gaskets, and packings. PPS is the precursor to a conductive polymer of the semi-flexible rod polymer family. The PPS, which is otherwise insulating, can be converted to the semiconducting form by oxidation or use of dopants.
Ultra-high-molecular-weight polyethylene is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.
Teijin Limited is a Japanese chemical, pharmaceutical and information technology company. Its main fields of operation are high-performance fibers such as aramid, carbon fibers & composites, healthcare, films, resin & plastic processing, polyester fibers, products converting and IT products.
Sailcloth encompasses a wide variety of materials that span those from natural fibers, such as flax, hemp or cotton in various forms of sail canvas, to synthetic fibers, including nylon, polyester, aramids, and carbon fibers in a variety of woven, spun and molded textiles.
SGL Carbon SE is a European company based in Germany. It is one of the world's leading manufacturers of products from carbon.
Technora is an aramid that is useful for a variety of applications that require high strength or chemical resistance. It is a brand name of the company Teijin Aramid.
Tenax is the brandname of Toho Tenax owned by Teijin for a carbon fiber. Tenax-7R is an adhesive particularly suited for welding plastics.
Teijin Aramid, formerly known as Teijin Twaron, is a company in The Netherlands that produces various high-strength fibers for industrial purposes, most notably their para-aramid, Twaron. Twaron finds applications in numerous markets, such as automotive, aerospace, civil engineering, construction, leisure goods, protective clothing, optical fiber cables, friction and sealing materials and more. The company has been part of the Japanese Teijin Group since 2000, prior to this they were a division of Akzo Nobel, division Industrial Fibers. Next to Twaron, the company markets Technora, Endumax and Teijinconex as well.
Carbon fiber-reinforced polymers, carbon-fibre-reinforced polymers, carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic, also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications.
M5 fiber is a high-strength synthetic fiber first developed by the Dutch chemical firm AkzoNobel. It is produced in the United States by the Magellan Systems International, which became a division of DuPont.
Unitika Ltd is a Japanese company based in Osaka. Primarily, the company produces various textiles, glass, plastics, and carbon fiber products. They are also known for their films, which are used in consumer products like athletic apparel and food packaging.
Oberbruch Industry Park, is a former 110-hectare (270-acre) site of Akzo Nobel in Heinsberg, Germany's most western district, near the Dutch border. It was founded in 1891 as a location for fiber industries. It is the birthplace of the German rayon and man-made fiber industry. Today, it is a diversified multi-user site, hosting companies from fields of industry such as high-performance fibers and energy technologies as well as from industrial biotechnology. Oberbruch Industry Park is the competency center for carbon (fiber) technology in North Rhine-Westphalia (NRW). Since 2000, the industry park has been operated by the Dutch energy company Nuon, the first independent industrial park operator not to come from the chemical industry. Since January 7, 2009 N.V. Nuon Energy has been part of Vattenfall.
Phormium is a genus of two plant species in the family Asphodelaceae. One species is endemic to New Zealand and the other is native to New Zealand and Norfolk Island. The two species are widely known in New Zealand as flax or their Māori names wharariki and harakeke respectively, and elsewhere as New Zealand flax or flax lily, but they are not closely related to the Northern Hemisphere's flax, which is native to the region extending from the eastern Mediterranean to India and has been used by humans since 30,000 B.C.
The Kasumigaseki Common Gate are twin tower buildings located in Kasumigaseki, Chiyoda, Tokyo, Japan. The buildings consist of East Tower and West Tower. Together with the adjacent Kasumigaseki Building, the first modern office skyscraper in Japan, the twin towers are landmarks in the Toranomon and Kasumigaseki area. The buildings are directly connected to Toranomon Station of Tokyo Metro Ginza Line.
