What is Technora®?
Premium para-aramid for long-term performance
Technora® is a high-performance para-aramid developed and produced by Teijin Aramid in Japan. Its unique copolymer structure provides long-term strength, thermal stability, and resistance to fatigue and chemicals. Trusted in offshore mooring and industrial belts and hoses, Technora® supports reliable operation in industries where materials are pushed to their limits.
How does Technora® perform?
Engineered to perform in the toughest environments
Technora® combines high tensile strength with resistance to heat, fatigue, and chemicals, making it a trusted choice for components that operate under constant load and environmental stress. The sections below detail how Technora® performs across key properties to support reliable performance over time.
High strength with stable performance under load
Technora® delivers a tensile strength of 3.1 to 3.6 GPa, offering high load-bearing capacity at low weight. With a modulus between 66 and 84 GPa, it provides the stiffness needed to limit elongation under stress. This balance of strength and dimensional stability supports reliable performance in applications where mechanical loads are constant or variable over time.
Stress-strain behavior
The stress-strain curve for Technora® shows a combination of high tensile strength and limited elongation. Compared to other high-performance fibers, Technora® maintains flexibility without compromising structural integrity. This makes it well suited for reinforcements that must absorb tension without failing, such as belts, cables, and composite structures.
Resistance to deformation
Technora® is engineered to maintain its shape under sustained load. It resists creep, shows no shrinkage in hot air, and maintains structural consistency across a wide temperature range. These properties contribute to long-term dimensional stability in components exposed to tension, pressure, or elevated heat.
Resistance to cyclic loading
Technora® maintains structural performance under repeated flexing, bending, or vibration. Its unique copolymer structure provides excellent fatigue resistance, supporting durability in applications where materials are subjected to dynamic stress over long operating cycles.
Thermal aging and creep performance
Technora® retains its strength over long periods at elevated temperatures. At 90°C, it maintains performance for over 10 years, compared to just 0.3 years for standard para-aramids. At 60°C, its projected lifespan exceeds 400 years. This resistance to thermal degradation reduces loss of mechanical properties and supports long-term performance in heat-exposed systems.
| Temperature | Standard para-aramids | Technora® | |
|---|---|---|---|
| 40 °C | 104 °F | 20 y | |
| 60 °C | 140 °F | 3 y | 400 y |
| 90 °C | 194 °F | 0.3 y | 10 y |
| 100 °C | 212 °F | 3.6 y | |
| 140 °C | 284 °F | 40 d | |
Thermal resistance in extreme environments
Technora® performs reliably across a wide temperature range. It has no melting point and decomposes only at 500°C (932°F). In continuous use, it maintains strength up to 200°C (392°F) and can tolerate short-term peaks of 400°C (752°F). Long-term exposure tests show that Technora® retains approximately 50% of its original strength after 54 days at 250°C (482°F), supporting durability in systems exposed to sustained heat.
Low-temperature stability
Technora® remains structurally stable at temperatures as low as –200°C (–328°F). It does not become brittle in subzero conditions, making it suitable for applications that operate in cold climates or experience rapid thermal cycling.
Flame resistance and fire behavior
Technora® is inherently flame resistant. It does not melt or drip when exposed to fire and is self-extinguishing. A high limiting oxygen index (LOI) further supports safe performance in high-temperature or flame-prone environments. Its low thermal conductivity also helps reduce heat transfer within layered systems.
Resistance to chemicals and solvents
Technora® offers strong resistance to a wide range of industrial chemicals, including hydrocarbons, organic solvents, acids, and alkalis. Its copolymer structure and closed filament morphology limit chemical penetration, helping the fiber maintain integrity in corrosive environments.
Stable across harsh conditions
Technora® is stable across a wide pH range, though exposure time and chemical concentration can influence resistance. These properties make it a reliable choice for reinforcement in oil and gas systems, chemical processing lines, and marine applications where material degradation poses a risk to long-term performance.
Environmental durability
With low moisture uptake and high dimensional stability, Technora® retains its properties under fluctuating humidity and exposure to environmental stress. It supports consistent performance in applications where materials must resist both mechanical load and chemical exposure over time.
Note on UV exposure
Technora® is not UV-stabilized and should be protected from direct sunlight in long-term outdoor applications. Surface degradation may occur with prolonged exposure.
Consistent performance across critical properties
Technora® combines the core advantages of high-performance para-aramids with enhanced resistance to fatigue, heat, and chemicals. Its copolymer structure supports long-term durability in environments where materials are exposed to mechanical load, thermal cycling, and chemical stress.
Benchmarking against commonly used materials
Internal testing shows that Technora® offers a well-balanced profile across key performance metrics. Compared to materials such as steel wire, carbon fiber, UHMWPE, and conventional para-aramids, it delivers strength, dimensional stability, and fatigue resistance while maintaining thermal and chemical integrity over time.
Supporting reliable material selection
This combination of properties makes Technora® a dependable choice for reinforcement in high-performance applications. It supports consistent performance over time and helps reduce material degradation in systems exposed to dynamic, thermal, or chemical challenges.
