- Applications
Technora® filament yarn adds value to numerous applications – including power-transmission belts for automotive, industrial and agricultural applications, as well as hoses, ropes and cables, flexible pipes, rubber products, protective clothing and composites – and is available in a wide range of linear densities and surface treatments.
- Applications
- 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® 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.
- 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.
- The superior hydrolysis of Technora®, combined with its excellent thermal, chemical and fatigue resistance, is increasingly valued in the offshore oil & gas industry
Properties
- Physical Form
- Typical Properties
- Properties
All Technora® filament yarns offer several high-performance properties, including exceptional strength and a thermal decomposition threshold of up to 500ºC.
- Properties
Unlike other high-performance aramids, Technora® offers both excellent primary properties, such as tenacity and strength, and secondary properties, such as heat and abrasion resistance.
- Mechanical Properties
- Technora® yarns have a very high strength, offering a tensile strength that is three to four times higher than polyester and polyamide yarns and eight times higher than steel on a weight-for-weight basis.
- Technora® yarns not only offer excellent fatigue resistance, with the ability to absorb dynamic loads for long periods of time, they also deliver very good abrasion resistance compared with many fibers, including other aramid solutions.
- The effects of temperature on the lifetime of Technora® yarn are relatively limited.
- Dimensional Stability
The dimensional stability of the reinforcing material is often key in many applications. The high modulus of Technora® ensures that the end-use product shows minimal deformation under a wide range of loading conditions.
- Thermal Properties
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.
- Chemical Resistance
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.
