Available since 1987, Technora® is a very strong para-aramid fiber developed and produced exclusively by Teijin Limited. This aromatic copolyamid (co-poly-paraphenylene-oxydiphenylene terephthalamide) is ideal for dynamic performance applications involving significant motion.
The polymer is closely related to DuPont's Kevlar®.
High tensile strength - Strong and light: weight for weight, Technora® is 8 times stronger than steel and 3 times stronger than fiberglass, polyester or nylon yarns.
Fatigue resistance - Shows little loss of strength even during repeated abrasion, flexing and stretching.
Dimensional stability - Stiff and highly oriented molecular structure leads to a high modulus of elasticity, low creep and low stress relaxation. Low thermal shrinkage, i.e., excellent dimensional stability.
Heat resistance - Thermal decomposition threshold of 500ºC, so Technora® can be used at 200ºC for long periods. At 250ºC, it maintains more than half of its room-temperature tensile strength.
Chemical resistance - Highly resistant to acids, alkalis and organic solvents; not vulnerable to damage caused by steam or sea water.
