Aramids are man-made fibers with enhanced structural properties, known for their incredible tensile strength. They are used in advanced products where light weight, yet high strength is needed.
Aramid fibers are made from long-chain synthetic polyamides. The chemical composition of para-aramid is poly para-phenyleneterephthalamide (PPTA). This polymer is composed of alternating benzene ring and amide groups, leading to a rigid, rod-like structure.
Characteristics of aramid fibers
Aramids fibers show resistance to many solvents and salt, but can be weakened by strong acids. While they are difficult to dye and sensitive to UV light, they are hard to burn, and instead of melting, they decompose.
The premium para-aramid. It’s six times as strong as steel, with great heat and chemical resistance, ideal for industrial and reinforcement applications.
Mechanical properties
Exceptional tensile strength, 2 – 3 times stronger than polyester and up to 6 times stronger than steel.
Dimensional stability
Shows minimal deformation or shrinkage under a wide range of conditions.
Thermal properties
Twaron® and Technora® are heat resistant up to 190°C (374°F) and 210°C (410°F) respectively. Both demonstrate excellent thermal stability and low heat conductivity.
Chemical resistance
High resistance to organic chemicals.
Other properties
Provides a long economic lifetime for the end product. Technically well-established flagship product.
Applications where aramids are used
Thanks to their high strength, heat resistance and lightweight properties, aramid fibers have made a major impact across a wide range of industries.
