The unique mechanical properties of Technora® make it suitable for use in applications over a very wide temperature range. In particular, Technora® has no melting point, and only starts to decompose once the ambient temperature reaches 500 °C (932 °F). For heat-resistant applications, exposure to temperatures above 250 °C (482 °F) is not recommended, to ensure fit-for-use strength retention. Furthermore, Technora® mostly maintains its mechanical properties at very low temperatures of – 200 °C (-328 °F) or below. The thermal isolation behavior of Technora® products is excellent due to the very low heat conductivity of the yarn. Furthermore, the high limiting oxygen index (LOI) of Technora® means that, when exposed to fire, the material ceases to burn as soon as it is removed from flame.
The unique molecular and crystalline structure of Technora®, in conjunction with the closed morphology of its filaments, prevents chemicals from penetrating the polymer structure of the material. Resistance to organic chemicals is therefore excellent, while resistance to inorganic chemicals varies according to pH value. Concentrated solutions of strong acids and strong bases will result in hydrolytic degradation, especially at elevated temperatures.
In a changing world, the core objective of Teijin Aramid remains the same: to make sure Teijin Aramid continues to be the leading aramid company in the world. Sustainable value creation and cost-efficiency are critical factors in our success and are strongly embedded in our company’s strategy. This means that, at Teijin Aramid, they strive to deliver products that meet our customers’ needs as efficiently as possible, while enabling them to reach the highest standards for performance.
Applications of Technora®
Technora® yarns excel in end products where the application is subjected to highly demanding conditions. In particular, demanding application environments require reliable reinforcement materials where the risk of failure is minimized. On the next pages key examples of applications are shown where Technora® offers the solution to these challenges.
Technora® provides short-cut fiber compound reinforcement, as well as twisted cords and fabrics, in a wide range of power-transmission belts for automotive, industrial and agricultural applications. Specifically, Technora® enhances a number of key rubber compound characteristics, such as resistance against abrasion, fatigue, puncture and tears, while also improving strength and hardness. Technora® also allows a low strain in the compound and ultimately helps in reducing energy loss. This makes Technora® ideal for high-end transmission belt applications in tough conditions.
Technora® is used as a hose-reinforcing yarn in a wide range of automotive hose applications, including radiator hoses, transmission-oil-coolant hoses, air-conditioning hoses and fuel hoses. Technora® is a unique material for automotive hoses due to its combination of high strength and superior heat resistance, including chemical resistance and dimensional stability. The overall outcome is superior end-product performance, improved reliability and extended product lifetimes with reduced maintenance.
Ropes and cables
With its unique combination of properties, Technora® yarn has a proven track record in challenging and demanding fields – including the mining, offshore and leisure industries – reinforcing and strengthening ropes and cables and making them safer and easier to use.
In particular, Technora® helps support key application qualities, such as fatigue life, and resistance to abrasion, heat, chemicals and seawater. Unlike steel, Technora® is not susceptible to corrosion. It also enables reduced weight and long-term dimensional stability.
Umbilicals and flowlines
The superior hydrolysis of Technora®, combined with its excellent thermal, chemical and fatigue resistance, is increasingly valued in the offshore oil & gas industry. Today, offshore oil companies around the world are using Technora® as a crucial reinforcement agent in umbilicals, in anti-bird caging tapes in flowlines, and other vital deepwater applications. Technora® is available in different grades and linear densities, further enhancing the essential properties needed to drive performance in deep-sea environments.
Sustainable value creation: Durability
The aramid products in Teijin Aramid’s portfolio are intrinsically capable of enabling sustainability. Technora® makes light- weight, long-lasting, durable solutions possible. In this way, it contributes to a reduction in carbon footprint, while allowing customers to conserve scarce raw materials and reduce the lifecycle cost of their applications. Furthermore, Teijin Aramid is optimizing its product offering in order to enable the reduction of aramid waste at their customers’ production sites. Remaining aramid waste is reused to create value-added products.
Research & Development
Innovation and cooperation are key drivers of sustainability and cost-efficiency. Because of this, Teijin Aramid has several dedicated research and development sites around the world, as well as customer support facilities. These facilities allow them to further develop standard aramid products to meet even the most demanding customer requirements. Improvement in understanding the behavior of aramid products under the actual application conditions contributes to the most effective use of their products.
In addition, combining their extensive knowledge of aramid products with their capacity for end-product design allows them to support their customers in the most optimal way. Their R&D facilities also allow them to react rapidly to urgent customer requests and business continuity issues. Working closely with their customers and partners across the value chain in this way allows them to fulfill their strategic objectives of creating and optimizing sustainable, cost-efficient solutions for existing markets as well as new ones.
Quality, Health, Safety & Environment (QHSE)
Across their global operations, staying ahead of relevant laws and regulations is integral to Teijin Aramid’s way of working, particularly when it comes to standards for environmental protection and for health and safety.
