What is Twaron®? Twaron® is Teijin Aramid’s flagship para-aramid. This highperformance material is known for its robust mechanical properties, chemical resistance, and thermal stability. Twaron® stands out in numerous industries for its exceptional durability. With over 30 years of expertise in aramid production, we offer a technically advanced product as well as the ability to customize Twaron® in partnership with our customers to meet diverse application needs. Twaron® para-aramid yarn excels in demanding environments, from ballistic defense to heat and cut protection. It serves critical roles...

Twaron® stands apart from other synthetic yarns with its unique blend of features: High strength: exceptional strength-to-weight ratio High modulus for stiffness and rigidity Dimensional stability: low creep and negative thermal expansion Excellent thermal stability, even at high temperatures High cut resistance for improved durability Good resistance to chemicals Low flammability for enhanced safety Electrically non-conductive Long, predictable lifetime Polyparaphenylene terephthalam

How is Twaron® produced? Dedicated specialists closely oversee Twaron® production, a three-stage process: polymerization, spinning into continuous filament yarn, and converting. 1. Polymerization In the first stage, monomers are combined to form a robust, fine-grained para-aramid polymer, known for its heat resistance and chemical resilience. This fine powder improves the quality of the plastic components. However, at this point, it does not possess the unique mechanical properties of yarn or pulp. 2. Continuous filament yarn spinning In the second stage, we dissolve the polymer in sulfuric acid,...

What types of Twaron® do we offer? Twaron® filament yarn Twaron® filament yarn comes in a variety of mechanical properties, categorized simply as: • Standard modulus with high elongation High modulus

Tailored for high performance Finishes and color options Twaron® has proven its value across a wide We apply a water-blocking finish to high- range of applications, including optical fiber modulus Twaron® yarn for optical fiber cables cables, hoses, tires, rubber goods, ballistic and use adhesion-activated fibers for rubber protection, protective clothing, ropes and products. While Twaron® typically comes in its cables, composites, and belts. Our yarns, natural yellow, we also offer black yarns for available in linear densities from 400 to applications where appearance is key, such as 800 dtex,...

Twaron® staple fiber Twaron® staple fibers are ideal for making gloves and apparel that protect against heat and cuts. These fibers come in both the standard yellow para-aramid color and black. We offer several specific lengths (40, 50, 60 mm) and a range of cut lengths from 76 mm to 100 mm. Choose from linear densities of 0.9, 1.7, and 2.5 dtex. For black fibers, options include 1.7 and 2.5 dtex densities. Beyond staple fibers, Twaron® is also available as stretch-broken yarns. Twaron® short-cut fiber Twaron® filament yarn can be processed into short-cut or dipped chopped fibers, ranging in...

Twaron® pulp To create Twaron® pulp, we cut the filament yarn, suspend it in water, and then fibrillate it. The pulp’s unique qualities, like fibril length and specific surface area, define its level of fibrillation. Thanks to its chemical and physical properties, Twaron® pulp increases stability and boosts the strength of the compounds it’s added to. We offer both dry and wet pulp in various fibril lengths and degrees of fibrillation, catering to a wide array of applications. These include friction products, sealing materials, and specialty papers, ensuring our customers have the best solutions...

A unique combination of properties Mechanical properties Twaron® yarns boast exceptional strength, with tensile strength two to three times higher than polyester and polyamide yarns, and up to six times higher than steel, when compared weight for weight. They maintain their key mechanical properties over a broad temperature range, ensuring durable reinforcement for a well-defined product lifetime. This lifetime varies based on load and temperature – higher loads and temperatures may shorten it. However, with proper safety factors, Twaron® significantly extends the economic lifespan of products....

Dimensional stability Dimensional stability is critical for many expansion coefficient of just a few ppm/°C applications, and the high modulus of Twaron® further improves stability under temperature ensures minimal deformation under load. variations. Additionally, Twaron® resists With very low and rapidly diminishing creep, shrinkage when exposed to hot air, maintaining products reinforced with Twaron® retain their the integrity of the final product in demanding dimensions over time.
