Technora® Para-Aramid Physical Properties

Technora® offers a multitude of great properties that make it an excellent choice for various applications. Their exceptional strength-to-weight ratio and high break strength provides high tensile strength and modulus, making them ideal for applications requiring robust and durable materials. Co para-aramid fibers like Technora® are great solution for applications where the fiber will be under constant load or a high cycle count, taking advantage of low elongation and creep properties.

Technora® Para-Aramid Resistance Guide

Technora® exhibits excellent resistance to high temperatures, maintaining it's mechanical properties even at elevated temperatures. Technora® maintains 90% of its heat resistance at continued exposure to 200°C.  This heat resistance makes them suitable for applications in thermal insulation and protective clothing. Additionally, Technora® demonstrate improved chemical resistance than standard para-aramids, enabling them to withstand higher exposure to acids, alkalis, and many organic solvents without significant degradation.  Finally, Technora® provides better inherent yarn on yarn abrasion in comparison to standard para-aramid fibers, ranking it as the top fiber in the aramid family.

This fiber will degrade with prolonged UV light exposure. These fibers will brown and weaken over time.  T240B has better UV resistance than the other types, but not recommended for prolonged UV exposure.  Please keep this fiber stored away in a dark room and in the UV protective bag the fiber was shipped in.

Technora® is better than standard para-aramids, but will still absorb atmospheric moisture up to 2% in weight. This fiber should be stored in a cool, dry room with low humidity. A desiccant bag was included with this fiber to prevent regain during transit and short-term storage at your facility.

Acid: Prolonged exposure to concentrated strong acids will cause degradation
Alkali: Degrades with prolonged exposure to Sodium Hypochlorite and other concentrated bases
Organic Solvent: Moderate degradation in Carbon Tetrachloride and Ethylene Glycol

Continuous Operating Temperature Range (°C): -200 to 200
Short Term Exposure (°C): 420
Degradation Temperature (°C): 500

Technora® Para-Aramid Performance Properties

  • High strength: At 25-28 grams per denier tenacity, Technora® fibers are some of the strongest available on the market.
  • Durability: These fibers offer high modulus, making them resistant to impact, puncture, and abrasion.
  • Lightweight: Technora® fibers offer very good strength-to-weight ratios, enabling the creation of lightweight products without compromising on durability.
  • Heat resistance:  Technora® fiber possesses excellent resistance to heat, allowing them to maintain their strength and integrity in even high-temperature environments than standard para-aramids.
  • Chemical resistance: These fibers very good resistance to various chemicals, including acids and solvents, making Technora® suitable for applications with chemical exposure.  Standard para-aramids however, these fibers will degrade with prolonged exposure to concentrated acids and bases, especially in high temperatures.
  • Flame resistance: Technora® offers excellent flame resistance, providing added protection in environments where fire hazards are a concern.
  • Dimensional stability: Co-para-aramids like Technora® fibers maintain their shape and structural integrity even under prolonged stress, ensuring long-term dimensional stability in applications like composites.
  • Energy absorption: These fibers have the ability to absorb and disperse energy, making them effective in reducing the impact force in applications such as ropes and cables.
  • Low Electrical Conductivity: Technora® is non-conductive, making them well suited for applications in electrical insulation and protective gear.
