- 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. 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.
Properties
- Typical Properties
- 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.
- 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.
